SMART on FHIR is the open standard that lets your app launch from inside an EHR’s clinician workflow, read structured patient data, and write back to the chart — without each EHR vendor reinventing the wheel. The specification is the same across Epic, Cerner, Athena, Allscripts, MEDITECH, eClinicalWorks, and NextGen. The implementation is not. Each vendor has Epic-specific scope handling, Cerner-flavored search parameters, Athena-specific approval flows. Building a SMART on FHIR app that works against any of them requires the spec. Building one that works against all of them requires shipping experience.
Taction Software’s SMART on FHIR developers have shipped 80+ EHR integrations across the major vendors. Engagements use the productized sprint path or dedicated engineers at $8K per engineer per month.
Our experts are ready to understand your business goals.
SMART on FHIR sits at the intersection of three disciplines:
Hire FHIR developers or vendor-specific specialists like Epic integration developers, Cerner developers, or HL7 integration engineers at $8K per engineer per month.
Apps that launch from Epic Hyperspace, Cerner PowerChart, AthenaOne, and other EHRs using the same SMART on FHIR codebase with vendor-specific configuration.
AI-powered launch apps that surface clinical reasoning, treatment matching, or decision support inside the clinician workflow.
Real-time transcription apps that launch from EHR encounter context and write back via DocumentReference.
Apps launched from patient portals (MyChart, HealtheLife, athenaPatient, FollowMyHealth, Healow) with patient-launch scope.
Server-to-server FHIR data pipelines for population health, analytics, and predictive modeling using SMART Backend Services flow.

FHIR developers at $8K per engineer per month.
For estimates, use the healthcare AI cost calculator and the EHR integration calculator.
Discovery Sprint $45K to $50K, MVP Sprint $95K, Pilot-Ready Sprint $145K. Full pathway $285K to $290K over 24 weeks. Dedicated engineers are $8K per engineer per month.
Discovery to a working pilot inside an EHR typically takes 18 to 28 weeks depending on the EHR target and whether vendor marketplace submission is required.
Epic, Cerner / Oracle Health, Athenahealth, Allscripts / Veradigm, MEDITECH Expanse, eClinicalWorks, and NextGen Healthcare. The team has shipped 80+ EHR integrations.
Yes. Provider launch (from within EHR clinician workflow), patient launch (from patient portal), and Backend Services (server-to-server, no user context) are all standard.
Yes. Most production SMART on FHIR apps share a core codebase with vendor-specific configuration layers for scope handling, search parameter quirks, and write-back behavior.
FHIR R4 is the data layer — resource models, search parameters, REST API. SMART on FHIR is the authorization and launch layer that sits on top, handling OAuth 2.0, EHR context, and scope negotiation. Most production apps need both.
Yes. Every engagement begins with a BAA.
