These are three fundamentally different ways to solve healthcare integration, and the right one depends entirely on your situation — control versus convenience, cost profile, scale, and how many systems you need to connect. Mirth Connect gives you maximum control and the lowest licensing cost but you run it. Redox offloads the operational burden as a managed platform. Custom direct integration gives total control at total responsibility. This guide lays out where each wins, how the costs really differ, and the hybrids in between. We build all three, so this is guidance, not a sales funnel for one. Get an Integration Platform Strategy Consultation (Free 45-Min Call) → (NDA-protected) Mirth specialist team · Redox specialist team · FHIR + HL7 expertise · healthcare integration credentials Three Fundamentally Different Approaches Mirth Connect (Open Source / NextGen Connect) Mirth Connect is a widely used interface engine — open source, now stewarded by NextGen (whose commercial edition is NextGen Connect) — that you host and operate yourself. See our Mirth Connect integration practice. Redox (Managed Integration Platform) Redox is a managed integration platform and network that handles much of the per-EHR connection burden as a subscription service. Custom Direct Integration Custom direct integration means building your own HL7 and FHIR interfaces to the systems you connect — maximum fit, maximum ownership. Cost Comparison Mirth Connect Cost Profile Low licensing cost (the open-source engine), but real cost in hosting, engineering, and ongoing operations — you own the running of it. Redox Cost Profile Subscription-based, trading higher recurring fees for far less operational overhead and faster multi-EHR reach. Custom Direct Integration Cost Profile Higher upfront build cost per integration, with cost concentrated in development and maintenance rather than licensing or subscription. Exact figures depend on scope, so we model them with you rather than quoting a generic number. Control & Customization Mirth: Maximum Control Mirth gives you deep control over transformations and routing, with the responsibility to build and maintain that logic. Redox: Minimum Maintenance Redox minimizes maintenance by standardizing connectivity, at the cost of working within the platform’s model. Custom: Full Control + Full Maintenance Custom gives total control over every behavior — and you maintain every line of it. Scalability & Performance Mirth at Scale Mirth scales well when engineered and operated properly; the constraint is your team’s capacity to run it reliably at volume. Redox at Scale Redox scales connectivity across many health systems without you operating the infrastructure, which is much of its appeal for growing SaaS products. Custom Direct at Scale Custom can be tuned for the highest performance on specific integrations, with scaling owned entirely by you. Use Case Decision Matrix When Mirth Connect Wins When on-premises is required, you want maximum customization, or you are cost-sensitive on licensing and have the team to operate it. When Redox Wins When you need speed to your first customer, you are building multi-customer SaaS needing many EHR connections, or you do not want the integration-operations burden. When Custom Direct Wins When you have a single strategic EHR relationship, the integration is performance-critical, or you have specific specialty requirements no platform serves well. Hybrid Approaches Hybrids are common and often optimal: Mirth + Redox (Mirth for on-prem/custom flows, Redox for breadth), Custom + Redox (custom where depth matters, Redox for reach), and Custom + Mirth (custom logic on top of a Mirth engine). We design the split deliberately. Migration Between Platforms We handle the realistic migration paths — Mirth-to-Redox, Custom-to-Redox, and Redox-to-Custom — mapping existing flows, validating parity, and cutting over without losing data continuity. See our software modernization practice. Our Recommendation Framework A simple decision tree: if on-prem or maximum control is non-negotiable, lean Mirth or custom; if speed and breadth across many EHRs matter most and you do not want to run infrastructure, lean Redox; if one deep, performance-critical EHR relationship dominates, lean custom. The most common mistakes are underestimating the operational cost of self-hosting Mirth, underestimating Redox cost at high volume, and building custom when a platform would have done. We help you avoid all three. Get an Integration Platform Strategy Consultation (Free 45-Min Call) → Frequently Asked Questions Is Mirth Connect dead now that NextGen acquired it? No. Mirth Connect is very much alive and widely deployed, available as open source with NextGen’s commercial NextGen Connect edition alongside it. Worth knowing: licensing terms changed for newer versions, which affects commercial use, while many organizations continue running established versions. We help you navigate the version and licensing question for your situation. Redox cost at scale? Redox’s subscription model can become a significant recurring cost as volume and connections grow, which is exactly the point where some organizations evaluate moving specific flows to custom or Mirth. Whether that is worth it depends on your volume and team — we model the crossover with you. Can we start with Redox and move to custom? Yes, and it is a reasonable strategy: use Redox for speed early, then move high-value or high-volume integrations to custom later. We design the architecture so that later move is manageable rather than a forced rebuild. What about 1upHealth, Particle, others? They solve adjacent problems — 1upHealth is FHIR-data-centric (strong for payer and aggregation), and Particle Health emphasizes network record retrieval. They can complement or substitute depending on your data model, and some stacks use more than one. We include them in the decision rather than forcing a three-way choice.

For a healthcare workload, all three major clouds — AWS, Microsoft Azure, and Google Cloud — are HIPAA-eligible under a BAA and fully capable. The real decision is rarely “which is most compliant”; it is which one fits your existing footprint, your EHR and vendor alignment, and the specific managed healthcare services you need. This comparison covers BAA coverage, the FHIR and imaging services, AI/ML, security tooling, and where each cloud tends to win. We build on all three and resell none, so this is selection guidance, not a push toward one. For the how-to of building a compliant architecture on these clouds, see our HIPAA-compliant cloud architecture guide; this page is the platform-selection comparison. Get a Healthcare Cloud Strategy Consultation (Free 60-Min Workshop) → (NDA-protected) Cloud engineering across AWS, Azure & GCP · HIPAA + BAA · healthcare cloud experience HIPAA BAA Coverage Comparison AWS HIPAA-Eligible Services AWS offers a broad list of HIPAA-eligible services under its Business Associate Addendum, covering the building blocks most healthcare workloads need. Azure HIPAA-Eligible Services Azure covers an extensive set of services under Microsoft’s BAA, with deep enterprise and identity tooling. GCP HIPAA-Eligible Services Google Cloud covers a wide range of services under its BAA, with particular strength in data and AI/ML. BAA Differences All three will sign a BAA and publish their covered-services lists; the practical differences are which specific services are in scope and how each structures the agreement. We confirm coverage for your exact architecture rather than assuming — see our HIPAA-compliant development practice. Healthcare-Specific Services FHIR & Healthcare Data Services All three build on the same FHIR standards. AI / ML for Healthcare These support our clinical NLP and healthcare AI work. DICOM & Medical Imaging Cost Comparison for Healthcare Workloads Cloud cost depends on your architecture, data volume, and commitments, and list prices shift — so any blanket “cheapest cloud” claim is misleading. The components that matter are compute, storage (with PHI retention and redundancy considerations), FHIR service pricing, and AI/ML inference cost (often the largest variable at scale). We model these for your specific workload rather than quoting generic figures. Security & Compliance Capabilities Each cloud has a strong native security posture-management tool: AWS Security Hub, Microsoft Defender for Cloud (formerly Azure Security Center), and Google Cloud Security Command Center. All three support the controls HIPAA expects; we implement them as part of any deployment — see our data security practice. Where Each Cloud Wins for Healthcare When AWS Is the Right Choice AWS often fits organizations that want the broadest service catalog and maturity, are already on AWS, or value HealthLake’s built-in ML. When Azure Is the Right Choice Azure often fits Microsoft-standardized organizations — deep Entra ID and Microsoft 365 integration — and those drawn to its enterprise and identity tooling. When GCP Is the Right Choice Google Cloud often fits data- and AI/ML-heavy workloads and teams that value its analytics and Vertex AI ecosystem. Multi-Cloud Considerations Multi-cloud can reduce lock-in and place workloads where they run best, at the cost of added complexity and operational overhead. It is a deliberate trade-off, not a default. Integration With Healthcare Vendors Epic on Each Cloud Epic can run on major clouds, and has notable ties with Microsoft Azure; the right host depends on your strategy and Epic’s current guidance — see our Epic integration work. Cerner on Each Cloud Since Oracle’s acquisition, Cerner (Oracle Health) aligns naturally with Oracle Cloud, though integration from other clouds remains possible. Major EHR Vendor Cloud Partnerships Vendor-cloud relationships evolve, so verify current specifics as part of your decision rather than relying on yesterday’s announcement. We help you confirm them. Migration Strategy Moving Between Healthcare Clouds Cloud-to-cloud migration of healthcare workloads is a real program — data, integrations, and compliance all move. See our software modernization practice. Multi-Cloud Architecture Where multi-cloud is warranted, we design clear workload placement and data-flow boundaries so it does not become unmanageable. Hybrid Cloud for Healthcare For organizations with on-premises constraints, we design hybrid architectures that keep sensitive workloads where they must live while using the cloud where it helps. Get a Healthcare Cloud Strategy Consultation (Free 60-Min Workshop) → Frequently Asked Questions Which is the most HIPAA-friendly? None is meaningfully “more HIPAA-friendly” — all three sign BAAs and offer extensive HIPAA-eligible services. Compliance depends on how you architect and configure the environment, not which logo is on it. The better question is which cloud fits your footprint, vendors, and needed services, which is what the workshop resolves. Can we run AI/ML on each? Yes. AWS (Comprehend Medical, SageMaker), Azure (Azure AI health capabilities, Azure ML), and Google Cloud (Vertex AI, MedLM) all support healthcare AI/ML. The right choice depends on your specific models, data gravity, and where the rest of your stack lives. On-premises vs cloud for PHI? Cloud is appropriate for PHI when configured correctly under a BAA, and most organizations run PHI in the cloud today. On-premises or hybrid still makes sense for specific data-sovereignty, latency, or contractual constraints. We design for your requirements rather than assuming one answer. BAA cost differences? The BAA itself is not a separate line-item charge on any of the three; cost differences come from the services you use and how you architect, not from signing the agreement.

For a healthcare mobile app, React Native and Flutter are both solid choices — and for many projects the decision matters far less than teams think. What actually moves the needle is how you implement HIPAA safeguards, device integration, and offline workflows, which both frameworks can do well. This guide focuses on the healthcare-specific tradeoffs — secure storage, biometric auth, health-device integration, and hireability — and is honest about where the choice is real and where it isn’t. One thing to settle up front: neither framework is “HIPAA-compliant” on its own. Compliance lives in how you implement encryption, storage, transport, logging, and your backend — not in the framework logo. Get Tech Stack Guidance for Your Healthcare App (Free 30-Min Call) → (NDA-protected) React Native + Flutter healthcare experience · mobile architect credentials · HIPAA + BAA The Comparison That Matters Most for Healthcare Healthcare-Specific Requirements Both Must Meet Both frameworks must support encryption at rest, secure storage, TLS in transit, biometric auth, audit logging, and integration with BAA-covered backends. Both can. The differences are in how, not whether. Where the Choice Actually Matters The choice matters most around your existing team and skills, specific device/SDK integrations, and whether you also need web from the same codebase. Where It Doesn’t For a standard patient-facing or clinician app, both deliver excellent results, and users cannot tell which framework built the app. Do not over-weight the decision. React Native — Healthcare Strengths and Weaknesses JavaScript / TypeScript Ecosystem React Native runs on the vast JavaScript/TypeScript ecosystem, so libraries, tooling, and patterns are abundant — useful when you are moving fast. Native Module Healthcare Integrations Its maturity means many native modules and wrappers already exist, including for common health integrations, reducing custom bridging work. HealthKit / Google Fit Integration Apple HealthKit and Google Fit integration are well-trodden in React Native, with established libraries. Hire-ability The JavaScript talent pool is enormous, so staffing a React Native team — including blending with web engineers — is typically easier and cheaper. Flutter — Healthcare Strengths and Weaknesses Performance Characteristics Flutter compiles to native and renders its own UI, giving consistent, high performance and pixel-identical UI across platforms — attractive for polished, animation-heavy apps. Single Codebase Including Web Flutter targets mobile, web, and desktop from one codebase, which can be compelling if a web client matters and you want true single-source UI. Native Module Maturity for Healthcare Flutter’s ecosystem is strong and growing but younger than React Native’s, so some specialized healthcare or device integrations may require more custom native work. Hire-ability Dart talent is growing but smaller than the JavaScript pool, so Flutter hiring can take longer, though strong teams exist. Healthcare-Specific Considerations HIPAA-Compliant Storage Implementation In both frameworks, PHI on-device should live in OS-backed secure storage (iOS Keychain, Android Keystore-backed) with encryption at rest — see our data security practice. Biometric Authentication Both support Face ID / Touch ID / fingerprint through platform plugins, appropriate for protecting PHI access. Background Health Data Sync Both handle background sync of health data, which matters for remote patient monitoring and wearables, with platform-specific background-execution limits to design around. Offline-First Healthcare Workflows Both support offline-first patterns essential where connectivity is unreliable, with encrypted local stores and sync-on-reconnect. HIPAA Implementation in Each Stack The HIPAA-relevant work is the same in both: encryption at rest via OS-backed secure storage, secure storage patterns that keep PHI out of insecure locations, audit logging of PHI access, and BAA-covered cloud services integration on the backend. We build these consistently regardless of framework — see our HIPAA-compliant development practice. Device & Sensor Integration Bluetooth Health Device Integration Both integrate Bluetooth/BLE health devices; React Native’s larger ecosystem sometimes offers more ready-made wrappers, while Flutter may need more custom work for niche devices. Wearable Integration Both integrate wearables and fitness platforms, feeding data into RPM and patient apps. Custom Medical Device SDK Integration For proprietary medical-device SDKs, either framework typically needs native bridging — the deciding factor is which platform the SDK supports best, not the cross-platform framework. Cost Differences Development cost is broadly comparable for similar scope. Maintenance cost depends more on architecture and team than framework. Hiring cost tends to favor React Native because of the larger JavaScript talent pool. For full cost context, see our healthcare software development cost guide. Our Recommendation Framework Choose React Native When You have or want JavaScript/web talent, value the largest ecosystem and easiest hiring, or need to share logic with a React web app. Choose Flutter When You want maximum UI consistency and performance, a single codebase spanning mobile and web, and your team is comfortable with Dart. When Native (Swift / Kotlin) Is the Right Answer Instead Go native when you need maximum performance, the deepest device and sensor integration, tight platform control, or you are building a regulated medical-device app where that control is part of the safety case — see our mobile app development practice for all three paths. Get Tech Stack Guidance for Your Healthcare App (Free 30-Min Call) → Frequently Asked Questions Which is more HIPAA-friendly? Neither is inherently more HIPAA-friendly — both can be made fully compliant, and both can be built insecurely. Compliance depends on your encryption, secure storage, transport, audit logging, and BAA-covered backend, all of which we implement the same way regardless of framework. Performance differences for telehealth video? For telehealth video, performance is driven mainly by the WebRTC/video SDK and your media architecture, not the cross-platform framework. Both React Native and Flutter integrate leading video SDKs and deliver strong results — see our telemedicine app development practice. Long-term maintainability? Maintainability comes from architecture, test coverage, and team continuity more than framework choice. Both are actively maintained and production-proven; the bigger long-term factor is keeping a team that knows your codebase. Which has better healthcare-specific libraries? React Native’s larger and older ecosystem currently has more ready-made libraries for common health integrations, which can reduce custom work. Flutter’s ecosystem is strong and growing; gaps are closable with native modules.

Choosing between Epic, Cerner (now Oracle Health), and athenahealth is one of the most consequential and expensive decisions a healthcare organization makes — and there is no single “best.” The right answer depends on your size, setting, specialties, budget, and integration needs. This comparison lays out where each platform tends to win, where each costs more, total-cost considerations, and migration realities. We are an EHR-vendor-neutral engineering firm: we do not resell any of these platforms, so this is guidance, not a pitch for one of them. For a focused two-way look, see our Cerner vs Epic article; this page adds athenahealth and the full decision framework. Get Independent EHR Selection & Implementation Guidance (Free 45-Min Consult) → (NDA-protected) EHR-vendor-neutral · integration experience across all three · BAA-ready · healthcare engineering credentials At a Glance — Quick Comparison Dimension Epic Cerner (Oracle Health) athenahealth Typical sweet spot Large health systems, academic medical centers Hospitals and health systems Ambulatory, independent and small-to-mid practices Delivery model Self-hosted or Epic-hosted Hosted / cloud (Oracle) Cloud-native, network-based Implementation effort High, multi-phase High for hospitals Lighter, faster for ambulatory Integration FHIR R4 + Connection Hub / App Orchard FHIR R4 + Code program FHIR R4 + Marketplace Best known for Integrated suite, MyChart Hospital breadth Cloud delivery, network services This is a high-level orientation; the sections below add the nuance, and your priorities determine the weighting. Epic — Strengths and Trade-offs Where Epic Wins Epic is strong for large, integrated health systems and academic medical centers — a broad, tightly integrated suite, a mature patient portal (MyChart), and deep adoption across big organizations. Where Epic Costs More That power comes with cost and effort: Epic implementations are large, multi-phase programs led by Epic, and the total investment is among the highest in the market. Best-Fit Organizations Large hospitals, academic centers, and integrated delivery networks that want one dominant platform and can fund the implementation. Cerner (Oracle Health) — Strengths and Trade-offs Where Cerner Wins Cerner has a large hospital footprint and strength across inpatient and health-system settings, with a long track record in acute care. Post-Oracle Acquisition Strategic Direction Since Oracle’s acquisition, some buyers weigh the platform’s evolving strategic direction and roadmap as part of the decision — a real consideration, though not inherently negative. Best-Fit Organizations Hospitals and health systems aligned with the platform’s direction, including organizations already invested in it. athenahealth — Strengths and Trade-offs Where athenahealth Wins athenahealth is cloud-native and network-based, with particular strength for ambulatory practices, independent groups, and small-to-mid organizations that value faster deployment and lower operational burden. Where athenahealth Doesn’t Fit It is generally a weaker fit for large inpatient and academic environments whose complexity favors the bigger hospital platforms. Best-Fit Organizations Ambulatory practices, independent and small-to-mid groups, and organizations that prioritize cloud delivery. Implementation Cost & Timeline Comparison Epic and Cerner hospital implementations are large, multi-phase programs typically measured in many months to multiple years, with correspondingly large budgets. athenahealth’s cloud model is generally faster and lighter to deploy for ambulatory settings. Exact cost and timeline depend heavily on your size, scope, and negotiation, so treat any single number with caution — we will model your specific case. Integration Capability Comparison FHIR API Maturity All three support FHIR R4, which US regulation mandates for patient-access and related APIs, so standards-based integration is possible with each — drawing on our FHIR API development work. Third-Party Marketplaces Each has a developer/marketplace program — Epic’s Connection Hub / App Orchard, Cerner’s Code program, and athenahealth’s Marketplace — with different access models and requirements. HL7 v2 Capabilities All three support HL7 v2 interfaces for traditional clinical integration, which remains essential in real environments — see our HL7 integration practice. Custom Integration Approaches Where the standard programs fall short, custom integration fills the gap. This is our core competency regardless of platform — see our Epic EHR integration work. Total Cost of Ownership (TCO) Considerations TCO is more than the license. It includes implementation, integration, training, ongoing support, and the hidden costs each platform carries — and those vary widely by organization and contract. Rather than quote misleading figures, we build a TCO comparison with you based on your size and scope, including the costs vendors do not advertise. Migration Considerations Moving Between These Platforms Migrations between these platforms are major programs. The data, integrations, and workflows all have to move — see our EHR migration services and dedicated Cerner-to-Epic migration practice. Migration Cost & Complexity Cost and complexity scale with environment size, integration footprint, and customization. We scope it precisely before you commit. Common Migration Triggers Consolidation, strategic-direction concerns, integration limits, and changing organizational needs are the usual triggers. Our Implementation & Migration Services Vendor-Neutral Guidance Because we do not resell any EHR, our selection guidance is independent — focused on the best fit for you, not a product we are paid to push. EHR Migration & Integration Where the EHR’s own configuration is led by the vendor, we own the surrounding work: migration between platforms (see EHR migration and Allscripts migration), and integration of your other systems with whichever EHR you run.

Get Independent EHR Selection & Implementation Guidance (Free 45-Min Consult) → Frequently Asked Questions Which EHR is best for a hospital, practice, or specialty? There is no universal best. Large hospitals and academic centers often favor Epic or Cerner; ambulatory and independent practices often favor athenahealth; specialty groups sometimes find none of the three fit well and consider a custom EHR. The right answer depends on your setting, specialties, budget, and integration needs — which is what a selection consult sorts out. Should we migrate from Cerner to Epic now? Only if there is a clear strategic reason — and the decision deserves a real evaluation, not a reflex. We give independent guidance on whether a move is justified and, if

Healthcare AI is the hottest budget line in the industry and one of the easiest to misjudge — the model is the cheap part, and the validation, integration, compliance, and ongoing inference are where the money goes.

Clinical NLP Specific use case $75K–$300K; platform / multi-use-case $300K–$1M+ — see our clinical NLP practice. Model Approach Cost Differences Foundation models (GPT-4, Claude, Gemini) + RAG are usually the fastest and lowest upfront path. Fine-tuning open source (Llama, Mistral) adds tuning and hosting cost but can lower long-run inference and enable on-prem. Custom model training is the most expensive and rarely necessary. Specialty-adapted models sit in between, tuned to your domain. We match the approach to your accuracy, cost, latency, and data-sovereignty needs rather than defaulting to the most expensive one. Deployment Cost Differences Cloud LLM provider (BAA-covered) is fastest to stand up; cost scales with usage. On-premises deployment has higher upfront cost but contains data and can lower per-inference cost at scale — see our on-prem LLM work. Hybrid balances the two. Edge / client-side suits specific low-latency or privacy cases. The right choice is as much a compliance decision as a cost one. Hidden Healthcare AI Costs The costs teams underestimate: LLM inference costs (recurring and easy to under-model at scale), clinical validation studies, FDA SaMD submission where applicable, bias and fairness testing, and continuous monitoring. We surface all of these up front so the budget is real, not just the build estimate. Compliance & Governance Cost Layers Budget for HIPAA-compliant deployment (see our HIPAA-compliant development and data security practices), audit-logging architecture, FDA SaMD where applicable, and AI governance and documentation — the controls that make healthcare AI defensible rather than just functional. ROI Calculation Framework We frame ROI around productivity gains (clinician and staff time recovered), cost avoidance (rework, errors, labor), and revenue acceleration (faster billing, captured charges). A pilot is the cheapest way to measure these on real data before committing to production scale. Get a Custom Healthcare AI Cost Estimate (Free 60-Min Workshop) → Frequently Asked Questions Should we start with PoC or production? Almost always a PoC or pilot first. For $50K–$150K you validate feasibility, accuracy, and value on real data before committing the much larger production budget — and if it does not work, you have saved the larger investment. We design pilots so the work feeds directly into production if it succeeds. Cloud LLM vs. on-prem cost? Cloud is cheaper and faster to start and scales with usage; on-prem has higher upfront cost but can lower per-inference cost at scale and keeps data in your environment. For many organizations the deciding factor is data sovereignty and compliance rather than cost alone. We model both for your volume. ROI timeline for healthcare AI? It varies by use case. High-volume, labor-heavy workflows (documentation, coding) tend to show return fastest; clinical and diagnostic AI takes longer because of validation and adoption. We build an ROI estimate with you so the timeline is grounded in your numbers. Can we use open-source models to reduce cost? Often, yes. Open-source models (Llama, Mistral) can reduce long-run inference cost and enable on-prem deployment, at the cost of more tuning and hosting work. Whether they lower your total cost depends on volume and accuracy needs, which we evaluate rather than assume.

“How much does a custom EHR cost?” is a fair question with an honest answer: it depends — on specialty coverage, integration depth, compliance path, and scale — and the range is wide. This guide breaks down real cost ranges by EHR type, the drivers that move the number, the compliance layers that add to it, and the ongoing costs after launch, so you can budget with eyes open. The figures below are typical ranges; your actual number depends on scope, which is exactly what a scoping call establishes. This page is about the cost to build a custom EHR. If you are budgeting for integrating with an existing EHR instead, see our EHR integration cost guide. For software cost more broadly, see our healthcare software development cost guide. Get a Detailed EHR Project Estimate (Free 45-Min Scoping Call) → (NDA-protected) EHR development experience · ONC certification capability · HIPAA + BAA · healthcare engineering team Why EHR Development Cost Varies So Widely Specialty Coverage A single-specialty EHR is far cheaper than one covering many specialties, because each specialty adds its own workflows, documentation, and rules. Multi-Site / Multi-Tenancy Requirements Supporting multiple sites or a multi-tenant SaaS model adds architecture and cost beyond a single-practice build. Integration Depth The number and depth of integrations — HL7, FHIR, lab, pharmacy, imaging — is one of the biggest cost drivers. Regulatory Path (ONC Certification, FDA) Whether you need ONC certification or fall under FDA regulation materially changes both cost and timeline. Cost Breakdown by EHR Type Specialty Practice EHR A single-specialty EHR (for example dermatology or orthopedics) typically runs $200K–$500K over a 6–12 month timeline — built on our custom EHR development practice. Multi-Specialty EHR A generalist EHR with multiple specialty modules typically runs $500K–$1.5M over 12–18 months. Enterprise / Hospital EHR An inpatient-plus-outpatient EHR with department modules is a major program, typically $1.5M–$5M+ over 18–36 months. Specialty Vertical EHR (Behavioral, Hospice, Home Health) A vertical EHR for behavioral health, hospice, or home health typically runs $300K–$800K over 9–15 months — see our behavioral health, hospice, and home health software practices. Cost Drivers The number moves with the number of user roles, the number of specialty workflows, the integration footprint (HL7, FHIR, lab, pharmacy, imaging), the reporting and analytics complexity, and the mobile app requirements (via our mobile app development practice). More of each means more cost. Compliance Cost Layers HIPAA (Baseline — Included) HIPAA safeguards are not an add-on in our work; they are built into every EHR as standard — see our HIPAA-compliant development practice. ONC Health IT Certification: $200K–$500K Add-On If you need certified health IT, ONC certification typically adds $200K–$500K depending on the criteria — see our ONC certification services. FDA SaMD Path (If Applicable): $300K–$1M Add-On If your EHR includes regulated software-as-a-medical-device functionality, the FDA path typically adds $300K–$1M depending on classification and validation needs. EHR Modernization vs. Build From Scratch Cost of Building New A new build gives you exactly what you want but carries the full cost ranges above. Cost of Modernizing Existing Legacy Modernizing an existing system can cost less than a full rebuild when the core logic is worth preserving — see our software modernization practice. When Modernization Saves Money Modernization usually wins when the existing system embodies hard-won, still-valid clinical logic and the problem is the technology, not the design. When New Build Is the Right Investment A new build wins when the existing system is fundamentally misaligned with where you are going, or when the modernization cost approaches the rebuild cost anyway. Ongoing Costs After Launch EHR ROI Considerations The case for custom is rarely just feature parity. It includes reduced vendor lock-in costs, the value of workflow customization (clinician time and satisfaction), integration flexibility you control, and long-term total cost of ownership versus off-the-shelf — where recurring license fees and workaround costs can close the gap with a custom build over time. Get a Detailed EHR Project Estimate (Free 45-Min Scoping Call) → Frequently Asked Questions Why so expensive vs. Athenahealth or Cerner Community? Those are licensed products whose development cost is spread across thousands of customers; you pay a recurring fee to use what they built for the general market. A custom EHR is built for you alone, so you bear the build cost — but you own the result, control the roadmap, and avoid the workarounds and lock-in that come with adapting your practice to someone else’s product. Can we phase the EHR build? Yes, and we usually recommend it. Phasing lets you launch a focused first release, validate it with real users, and fund later phases from a position of evidence rather than committing the entire budget up front. A discovery workshop defines those phases. How does cost compare to Epic implementation? They are different cost models. Epic is licensed and implemented rather than built, and for hospitals the licensing-plus-implementation cost is substantial and ongoing. A custom EHR is a build cost you own outright. Which is cheaper over time depends heavily on your size and how well a packaged system fits — we will model the comparison honestly for your situation. Will ONC certification be required? It depends on your customers and use case. If providers using your EHR need Certified EHR Technology (for example, for CMS programs), certification is required; many specialty and internal builds do not need it. We help you determine this early so it is budgeted correctly — see our ONC certification services.

When a healthcare platform is approaching a scale ceiling, planning a major new capability, or heading into modernization, the smartest first move is to understand the architecture you actually have. Taction Software performs healthcare software architecture reviews — scalability, reliability, security, integration, and compliance architecture — and delivers a risk-prioritized roadmap with effort and cost estimates and reference-architecture recommendations. It is a scoped, two-to-four-week engagement that turns architectural uncertainty into a plan. This is a system-level review.

Areas We Review Scalability & Performance Current-state capacity assessment, scaling bottlenecks, database architecture, and caching and CDN strategy — whether the system can grow with you. Reliability & Operations High-availability architecture, disaster-recovery posture, monitoring and observability, and incident-response readiness — whether it stays up and recovers. Security Architecture Identity and access architecture, PHI data-flow security, network segmentation, and encryption strategy, drawing on our data security practice. Integration Architecture EHR / HL7 / FHIR integration (via our HL7 and FHIR expertise), third-party integration, API architecture, and event-driven patterns — the connective tissue healthcare depends on. Compliance Architecture HIPAA technical-safeguards coverage, audit-logging architecture, and BAA boundary analysis, building on our HIPAA-compliant development practice. Deliverables You Receive You receive: an executive architecture summary, detailed findings with diagrams, a risk-prioritized roadmap, effort and cost estimates, and reference-architecture recommendations — enough to decide and to act. Review Format Stakeholder Interviews We interview the engineers and leaders who know the system, surfacing context no document captures. Documentation Review We review existing architecture and operations documentation for what is designed and what has drifted. Code & Configuration Inspection We inspect code and configuration to see how the architecture is actually implemented, not just described. Live Demos & Walkthroughs We walk through the running system to ground findings in reality rather than intent. Findings Workshop We close with a workshop that takes your team through the findings and roadmap so they are understood and actionable. Engagement Types We offer a standard architecture review (2–4 weeks), a focused domain review (security, scale, or integration), a pre-modernization architecture review, and an architecture validation for a major build decision — matched to your need. What Happens After the Review Continue With Us on Remediation / Modernization If you want execution, we can take the roadmap into remediation or modernization on our custom healthcare software foundation — but only if it serves you. Continue Independently — Deliverables Are Yours The deliverables are yours. You can hand the roadmap to your own team or another vendor; the review is genuinely vendor-neutral. Stakeholder Workshop to Operationalize Findings We can run a workshop — or support a fractional CTO engagement — to operationalize the findings and keep momentum. Schedule an Architecture Review Scoping Call → Frequently Asked Questions How long does an architecture review take? Two to four weeks for a standard review, shorter for a focused domain review, depending on system complexity and stakeholder availability. We scope it on the call. What access do you need? Typically architecture and operations documentation, time with your engineers and leaders, read access to code and configuration, and a walkthrough of the running system. We work within your access and security constraints, under NDA. Will you recommend specific vendors / technologies? Yes, where it helps — and our recommendations are vendor-neutral, based on your needs rather than what we sell. We are transparent that we can also build, but the recommendations serve you, and you are free to act on them however you choose. Confidentiality? Every review is NDA-first. Your architecture, code, and findings stay confidential, and any PHI is governed by a BAA.

A code audit answers a precise question: what is actually in this codebase, and what will it cost you? Taction Software performs healthcare software code audits — code quality, security, architecture, technical debt, and healthcare-specific PHI and integration patterns — for acquirers, investors, CTOs, and organizations inheriting a codebase. You get a risk-rated findings report with code references, remediation effort and priority estimates, and a refactoring plan — and, if you want it, a team that can fix what the audit finds. This is a codebase-level audit. For investor-facing deal evaluation, see our healthcare tech due diligence; for organization-wide security posture, see our healthcare security audit.

Inheriting a Codebase (Vendor Handoff, Team Transition) When you inherit a codebase from a departing vendor or team, an audit gives you a true map before you depend on it. Pre-Modernization Baseline Before modernizing, an audit establishes the baseline — what to keep, refactor, or replace — feeding directly into our software modernization work. Investor Tech Confidence For investors, a code audit converts technical uncertainty into a risk-rated picture they can act on. Healthcare Compliance Audit Preparation Ahead of a compliance review, an audit surfaces the PHI-handling, logging, and encryption issues that would otherwise become findings — see our HIPAA-compliant development practice. What Our Code Audit Covers Code Quality Static analysis across the codebase, code smell and anti-pattern detection, documentation quality, and a maintainability index — an objective read on how healthy the code is. Security Review OWASP-aligned security code review, healthcare-specific vulnerability patterns, secrets and credentials in code, and a dependency vulnerability audit — complementing our penetration testing and data security work. Architecture Assessment Architecture pattern adherence, coupling and cohesion analysis, scalability assessment, and technical debt quantification — whether the structure will hold up as you grow. Healthcare-Specific Review PHI handling patterns, audit logging implementation, HL7 / FHIR integration code (via our HL7 and FHIR expertise), and encryption implementation — the things a generalist code review simply does not check. Deliverables You receive: an executive code quality report, detailed findings with code references, remediation effort and priority estimates, a risk-rated issues list, and a recommended refactoring plan — enough to make a decision and to act on it. Engagement Types We offer a quick audit (1 week, single codebase), a comprehensive audit (2–4 weeks), a pre-acquisition diligence audit, and an inherited-codebase onboarding audit — matched to your situation and timeline. Code Audit + Remediation Path Audit Identifies Issues; Remediation Engagement Fixes Them The audit is independent and honest. If you then want the issues fixed, we can do that as a separate remediation engagement — audits frequently lead to remediation or modernization several times the audit’s value, and that is fine, but the audit stands on its own. Modernization-Focused Audits When the goal is modernization, we focus the audit on what to keep, refactor, or replace. Security Remediation Audits When the driver is security, we focus on the vulnerabilities and the path to closing them. Schedule a Code Audit Scoping Call (free, NDA-protected) → Frequently Asked Questions How long does a code audit take? From one week for a focused single-codebase audit to two to four weeks for a comprehensive one, depending on codebase size and depth. We scope it precisely on the call. Do you need our source code? Yes — a meaningful code audit requires access to the source, which is exactly why we work NDA-first and handle your code under strict confidentiality. We can work within your access and environment constraints. What languages do you support? We audit across the stacks common in healthcare software — Node.js, Python, Java, .NET, and PHP, plus mobile (Swift, Kotlin, React Native, Flutter). Tell us your stack on the call and we will confirm fit. Will you also fix the findings? We can. As healthcare software engineers we are able to remediate what we identify in a separate engagement, but the audit itself is independent — you are free to take the findings and fix them yourself or with another vendor. NDA? Always. Every code audit is NDA-first; your source code and findings stay confidential.

When you are evaluating a health-tech investment or acquisition, the technology and compliance risk is often the part your team can least afford to get wrong — and the part a generalist DD firm misses. Taction Software provides healthcare-specialized technology due diligence for VC firms, PE deal teams, and corporate acquirers: architecture and code-quality review, compliance and security assessment, scalability and team evaluation, and a risk-rated report your deal committee can act on — typically in two to three weeks, with expedited turnaround available. Schedule a Tech DD Scoping Call (we respond within 4 business hours) → (NDA-first) Healthcare DD specialization · independent, conflict-free findings · anonymized VC/PE references on request What We Evaluate Architecture & Technical Foundation Architecture quality and scalability, technology stack maturity, technical debt, and cloud / infrastructure cost efficiency — whether the platform can carry the thesis or will need expensive rebuilding. Code Quality Code review and quality metrics, test coverage, security practices, and documentation — what the codebase actually is beneath the demo. Compliance & Risk HIPAA and SOC 2 status (and any other frameworks the target should hold), a BAA inventory, penetration test history, and security incident history — drawing on our HIPAA risk assessment, SOC 2, penetration testing, and security audit expertise. Team & Operational Readiness Engineering team strength, operational maturity, vendor and tool dependencies, and key-person risk — because the team and operations are as much of the asset as the code. Deliverables You receive: an executive summary for the deal committee, a risk-rated findings report, remediation effort and cost estimates, a technology investment thesis validation, and a red-flag inventory — written for investors making a decision, not engineers reading a manual. Engagement Types We support pre-term-sheet due diligence, pre-close confirmatory diligence, portfolio company tech audits (post-investment), and bolt-on acquisition tech assessments — matching the depth to where you are in the deal. Why Healthcare-Specialized Tech DD Matters Healthcare-Specific Compliance Risks HIPAA exposure, missing BAAs, and unaddressed security obligations are liabilities a generalist DD will not weight correctly — and they can change valuation or kill a deal. Integration Complexity Buyers Often Miss Healthcare products live or die on EHR and data integration. We assess the real integration footprint and its fragility, which buyers routinely underestimate. Regulatory Roadmap Impact Looming requirements — interoperability rules, certification, FDA considerations — can impose major near-term cost. We surface them so they are priced into the deal. Clinical Workflow Reality vs. Demo A polished demo is not proof clinicians will use the product. We assess clinical-workflow fit and adoption reality, not the sales narrative. Timeline & Engagement Model Standard Turnaround: 2–3 Weeks Most diligence completes in two to three weeks, matched to deal timelines. Expedited (1 Week) Available When a deal is moving fast, we offer expedited one-week turnaround. Document Review + Stakeholder Interviews + Tech Demos We combine document and code review, stakeholder interviews, and technical demos to form an evidence-based view rather than a paper one. Confidentiality & Independence NDA-First Engagement Every engagement starts with an NDA. Discretion is a given in deal work. No Conflicts with Target Company We confirm we have no conflicts with the target before engaging, so our findings are credible to your committee. Independent Findings Our findings are independent and honest — including the inconvenient ones. That independence is the entire value of diligence, and we protect it even though we also do build work. Schedule a Tech DD Scoping Call (we respond within 4 business hours) → Frequently Asked Questions How long does a tech DD take? Two to three weeks for a standard engagement, with expedited one-week turnaround available when the deal requires it. We scope to your close date in the first call. What about confidentiality? We work NDA-first and confirm we have no conflict with the target before we engage. Deal information stays confidential, and our findings go only to you. Will you remediate post-close? Yes, if you want us to — through portfolio-company tech work, modernization, or a fractional CTO engagement. We keep that separate from the diligence itself so the findings remain independent and honest. See our software modernization practice. Do you support international diligence? Yes. We assess targets outside the US as well, accounting for the relevant data-protection and regulatory regimes alongside the technical evaluation.

Plenty of health-tech startups and healthcare organizations need senior technology leadership but cannot justify — or cannot yet find — a full-time CTO. A fractional CTO fills that gap: experienced healthcare technology leadership on a part-time, ongoing basis. Taction Software provides fractional CTO services for health-tech startups and healthcare organizations — technology strategy, architecture decisions, team building, compliance leadership, and board and investor communication — backed by a team that can also build what we recommend if you want it. Schedule a Free Fractional CTO Fit Conversation (45 min) → (no obligation) Senior healthcare technology leaders · HIPAA & healthcare credentials · references on request When Fractional CTO Services Make Sense Health-Tech Startup Without Senior Tech Leadership Early-stage health-tech companies often have strong engineers but no senior leader to set technical direction, make architecture and build-vs-buy calls, and own compliance. A fractional CTO provides that without a full-time hire. Healthcare Org With Vacant CTO Role When a healthcare organization’s CTO role is vacant, a fractional CTO keeps technology decisions moving and the team supported rather than drifting. Pre-Hiring Bridge for CTO Search A fractional CTO can bridge a CTO search — leading in the interim, and even helping define and evaluate candidates for the permanent role. Strategic Technology Decisions Need Senior Input Sometimes the need is episodic but high-stakes — a major architecture decision, a platform bet, an audit. A fractional CTO brings senior judgment to those moments. What Our Fractional CTO Services Include Strategic Technology Leadership Technology strategy and roadmap, architecture decisions, build-vs-buy decisions, and vendor and partner selection — the senior calls that shape everything downstream. Team Building & Management Engineering hiring support, engineering team coaching, and process and practice establishment so the team you have (and the team you build) performs. Compliance & Risk Leadership HIPAA and healthcare compliance leadership, security program oversight, and audit and certification strategy — drawing on our HIPAA-compliant development, HIPAA risk assessment, security audit, and ONC certification practices. Board & Investor Communication Board technology updates, investor due diligence support, and strategic communication that translate technology into terms boards and investors act on. Engagement Models We work in four common shapes: a monthly retainer (most common), project-based fractional CTO, bridge CTO during a search, and advisory CTO with equity for early-stage companies. Time Commitments We scale to the need: light (10–20 hours/month), standard (20–40 hours/month), heavy (40–80 hours/month), and full-time fractional for intensive periods. Who We’re a Good Fit For We are a strong fit for health-tech startups (pre-Series A through Series C), specialty practices building internal software, mid-market payers without a senior CTO, and healthcare investors needing CTO support for portfolio companies. Pricing Monthly Retainer Ranges Retainers scale with the time commitment — from a few thousand dollars a month for light advisory up to the $15K–$30K/month range for heavy or near-full-time engagement. Project-Based Fees For episodic needs, we scope a fixed project fee rather than a retainer. Equity Considerations for Early-Stage For early-stage companies, we can structure part of the engagement as equity where it makes sense for both sides. What Sets Our Fractional CTOs Apart Our fractional CTOs are senior healthcare technology leaders with real backgrounds in healthcare software, compliance, and engineering leadership — not generalists learning healthcare on your time. We share specific CTO bios, credentials, and references during the fit conversation so you can evaluate the exact person who would lead your engagement. Schedule a Free Fractional CTO Fit Conversation (45 min) → Frequently Asked Questions How is this different from consulting? A consultant advises and leaves; a fractional CTO holds the leadership role — owning technology decisions, leading your team, representing technology to your board, and staying accountable over an ongoing engagement. It is leadership, not a report. Can you also build the software you recommend? Yes — and we are transparent about it. Having a team that can execute is an advantage, but the fractional CTO’s job is your best interest. We will tell you honestly when building with us is the right call and when it is not, and you are always free to use other vendors. What about confidentiality and conflict of interest? We work under confidentiality and are upfront about the potential conflict that comes with also being a development shop. We manage it by giving you independent, honest recommendations, disclosing where our interests could be involved, and never steering you toward work that does not serve you. How long is a typical engagement? Fractional CTO engagements are usually ongoing and measured in months to years, though bridge engagements during a CTO search are shorter by design.
