The build-vs-buy question for an EHR is almost always asked with the wrong default. Teams assume "buy" is the safe, cheap option and "build" is the expensive, risky one. Sometimes that's true. Often it isn't — because the real choice isn't binary, and the expensive failures we get called to rescue usually come from picking the wrong end of a spectrum nobody mapped.
Here's the framework we use in the first conversation, before anyone has committed to anything.
The default answer is buy
If your organization delivers care and you need a system of record — scheduling, charting, orders, billing, a patient portal — you should buy. Epic, Cerner (Oracle Health), athenahealth, eClinicalWorks, and a dozen others have spent decades and billions encoding clinical workflows, regulatory edge cases, and payer integrations you do not want to rebuild. A from-scratch EHR is a 7-figure, multi-year commitment with an ongoing compliance burden that never ends.
We will talk you out of building a full EHR more often than into it. That's not modesty — it's where the math lands for most organizations.
What buying actually gets you
- Certified clinical workflows and a defensible compliance posture out of the box
- Payer and clearinghouse connections that already work
- A vendor accountable for keeping pace with regulatory change (USCDI, information-blocking rules, e-prescribing mandates)
- An ecosystem of integrations other vendors already support
Where off-the-shelf EHRs fail
The failure mode isn't the core EHR — it's everything the vendor won't build for you. The specialty workflow that doesn't fit their data model. The patient experience that ends at a 2009-era portal. The integration with the device or app that's central to your business. The analytics the reporting module can't express.
This is where teams make the expensive mistake: they either bend their entire operation to fit the vendor's assumptions, or they rip the whole thing out to build custom. Both are usually wrong.
The build case: three patterns
Custom development is the right call in three situations:
1. The product IS the software
If you're a digital health company and the clinical software is your product — not a back-office tool — you're building. A telehealth platform, an RPM service, a condition-specific care app: these have no off-the-shelf equivalent because the workflow is the differentiator.
2. A specialty or model the market ignores
Behavioral health, complex care coordination, home-based care, value-based contracts with unusual attribution logic — the long tail of care models that generic EHRs serve badly. Here a focused custom system, or a heavy custom layer, beats forcing a square peg into Epic.
3. Integration and experience, not records
Most "we need a custom EHR" requests are really "we need a great experience and a few workflows that the EHR can't deliver." That's not a build-an-EHR problem. It's a build-on-top-of-the-EHR problem.
The hybrid most teams actually need
The answer that fits the largest share of our healthcare clients is neither pure buy nor pure build. It's: keep the certified EHR as the system of record, and build the differentiated layer on top of it using SMART on FHIR.
- SMART on FHIR apps that launch inside the EHR for clinicians — your workflow, their chart, single sign-on
- A modern patient-facing experience that reads and writes to the EHR via FHIR R4
- Bidirectional integration (most teams stop at read; the value is usually in write-back)
- A custom analytics layer fed by bulk FHIR export, not the vendor's reporting module
You get the compliance and breadth of the bought system and the differentiation of custom, without owning a system of record you'll regret.
The TCO nobody quotes you
Both paths have costs the sales conversation hides. For buy: per-provider licensing that scales with growth, integration fees, implementation consultants, and the opportunity cost of workflows you can't change. For build: not the v1 cost but the ongoing one — security, compliance re-certification, keeping up with regulatory change, and the team you need to maintain it for as long as it runs.
A custom EHR isn't expensive because it's hard to build once. It's expensive because it's yours to maintain forever.
A decision checklist
- Is a system of record your product, or a tool that supports it? Product → lean build. Tool → buy.
- Can a certified EHR do 80% of what you need? If yes, buy it and build the other 20% on FHIR.
- Is your differentiation in the records, or in the experience and integrations around them? Almost always the latter.
- Do you have — and will you keep — a team to own compliance for the life of the system? If not, don't build the core.
- What's the cost of the workflows you'd have to give up by buying? Quantify it before deciding.
