SMART on FHIR Cost Estimator

Every estimate starts with hours. At our blended rate of $50 per hour, 400 hours costs $20,000 and 1,600 hours costs $80,000. Estimating hours for each component, then multiplying by the rate, gives a transparent budget that is easy to review and challenge.

Launch type, resources, write-back, interface and target EHRs must be decided before a reliable estimate is possible. Vague scope produces vague estimates. A short discovery phase that fixes these decisions is usually the cheapest way to avoid budget overruns later in the project.

Authorization, FHIR resource handling, data mapping and vendor testing often consume as much effort as building the interface itself. Teams that estimate only screens and features usually underestimate total cost significantly, especially for apps that must work across more than one EHR platform.

Supporting one EHR vendor is the baseline. Each additional vendor adds testing, configuration, program onboarding and sometimes code changes for differences in FHIR implementation, so multi-EHR apps cost more even though the core app logic stays the same across platforms.

Security, audit logging, encryption and HIPAA safeguards are part of every estimate rather than optional extras. Healthcare customers will review these controls before deploying the app, so leaving them out of early estimates only moves the cost later, usually at a higher price.

Early estimates are ranges because unknowns remain, such as vendor review timelines or customer-specific configuration. Ranges narrow as scope is confirmed. We present low, typical and high scenarios, so leadership understands both the likely budget and what could push the project toward the upper end.

A clinician-facing app that launches from one EHR and displays a summary from four to six FHIR resources typically takes 200 to 500 hours. It suits pilots, internal tools and early product validation where speed and a modest budget matter most.

A tool that reads patient data, applies clinical logic and presents recommendations inside the EHR workflow typically takes 500 to 1,200 hours. Clinical validation, clear explanations and possible regulatory review add effort compared with a simple data viewer. Regulatory status is checked.

An app that captures information and writes notes, observations or orders back into the EHR typically takes 800 to 1,800 hours. Write-back validation, permissions, vendor review and careful testing of every data element drive the higher range. Clinicians approve every write.

A patient app using standalone launch to show records, results and medications typically takes 600 to 1,600 hours. Mobile and web interfaces, patient authentication, accessibility and support for several health systems all influence where a project falls in this range.

A product sold to many health systems, supporting two or more EHR vendors with read and write features, typically takes 1,600 to 4,000 hours. Vendor programs, deployment tooling and support processes are significant parts of the total budget. Phased delivery helps.

An app that adds AI, such as chart summarization or documentation assistance, inside a SMART on FHIR launch typically takes 1,000 to 3,000 hours. Evaluation, guardrails and monitoring add effort. Our EHR AI integration work covers these builds. Model fees are separate.

Write down who uses the app, where it launches, what data it needs and what decisions it supports. A precise use case keeps scope stable. Our SMART on FHIR app development page explains common use cases that help frame this step.

List every FHIR resource the app will read or write, then estimate 20 to 60 hours for each, depending on complexity. Our glossary entry on SMART on FHIR explains how resources and launch context work together in practice. Fewer resources cost less.

Count screens and workflows, then estimate 20 to 40 hours per screen for design and development, more for complex interactive tools. Include accessibility and clinician usability testing, because apps that slow clinicians down are quickly abandoned regardless of their technical quality.

Add 40 to 120 hours per EHR vendor program, plus 60 to 160 hours for security controls, audit logging, encryption and security review documentation. Healthcare customers will request this evidence before deployment, so it must be included in any realistic estimate.

Add roughly 20 to 30 percent of development hours for testing across sandbox and customer environments, plus 20 to 100 hours per initial customer deployment. Testing often reveals vendor differences in FHIR behavior that must be handled before launch. Budget for both.

Add 15 to 25 percent contingency for unknowns, then multiply total hours by the hourly rate. At $50 per hour, a 1,000-hour estimate becomes $50,000. Compare this figure with our HL7 FHIR integration cost guide for broader context. Review assumptions regularly.

Starting with read-only access avoids write-back validation and extra vendor review in the first release. Many apps prove value with read-only features, then add write-back once users confirm which documentation steps would save the most time in practice. Feedback guides later phases.

Supporting one EHR vendor first reduces program onboarding, testing and configuration effort. Choose the vendor your first customers use, then add others once the core app is proven, reusing FHIR components to lower the cost of each additional platform significantly.

Every resource adds effort. Use only the resources the first release genuinely needs, and add others later based on user feedback. Narrow data scope also simplifies security review, because customers approve fewer permissions for the initial deployment of the app.

Authorization flows, FHIR clients, logging and security patterns can be reused across apps and vendors. Our FHIR API development team applies proven components, reducing development time compared with building every integration piece from the beginning. Reliability improves as well, because proven code has already been tested.

Preparing security documentation alongside development avoids delays when customers request it. Reusable documentation, covering architecture, encryption, access control and incident response, shortens every later customer review and reduces the internal time needed to answer lengthy security questionnaires. Deals close faster as a result.

For products sold to many health systems, configuration tools and deployment checklists reduce per-customer effort dramatically. Investing in tooling early costs a little more upfront but lowers the cost of every new customer deployment for the life of the product.
