Custom Clinic EMR vs Epic / Cerner: 2026 Buyer Comparison

The verdict in three sentences

A market suite such as Epic or Cerner runs at enterprise scale (six figures a year), with no ownership and a standardised patient journey, whereas a custom build costs 90,000-200,000 EUR plus 15 % maintenance/year. Custom wins on three fronts: zero booking commission, mastered HL7/FHIR interoperability, and full patient-data ownership. For a group of 15 practitioners or more, break-even sits between 4 and 6 years, with an owned asset at the end.

Market suite or bespoke build: the real comparison

The choice is not just the monthly price. The table below sets the two models against the criteria that bind a clinic for ten years.

For 20 practitioners at 110 EUR/month-equivalent, a mid suite is 26,400 EUR/year, over 132,000 EUR across five years without ever owning the platform.

Where break-even sits in 2026

The tipping point depends on practitioner count and amortisation period. Here is a 2026 projection for a custom build at 150,000 EUR (maintenance 22,500 EUR/yr) against a suite at 110 EUR/practitioner/month.

The purely financial threshold is around 35-40 practitioners over five years, but non-monetary gains (owned data, zero commission, interoperability) often bring the decision forward.

Mini case study

Dr. Reynolds leads a 30-practitioner medical group. On a market suite at 120 EUR/practitioner/month, the bill reaches 43,200 EUR/year, over 216,000 EUR across five years. A custom build at 170,000 EUR (maintenance 25,500 EUR/yr, hosting 900 EUR/month) totals 307,300 EUR over five years, apparently costlier, but removes all booking commission, makes the clinic the data owner and opens HL7/FHIR interoperability with the partner laboratory. Over eight years, custom moves ahead and the asset stays on the balance sheet.

FAQ

Do market suites charge a booking commission? Depending on the plan, certain booking or visibility features can be billed. A custom build eliminates any commission by design.

Does custom handle HL7/FHIR interoperability? Yes, and it is a major argument: a bespoke build natively embeds HL7/FHIR standards to exchange with labs, imaging and hospitals.

From how many practitioners is custom profitable? The five-year financial break-even is around 35-40 practitioners. Below that, non-monetary advantages (data, reversibility) sometimes still justify it.

What happens to patient data if you switch vendor? With a suite, reversibility is often limited. With custom, the clinic owns the data and its schema: reversibility is total.

How long to migrate from a market suite? Expect 4 to 7 months including historical migration, parallel running and training, to avoid any service interruption.
