The verdict in three sentences
Making a healthcare product interoperable in HL7/FHIR represents in 2026 an investment of 20,000 to 60,000 EUR in Dublin, including data mapping and secured exchanges. A realistic timeline runs 3 to 6 months, maintenance 500 to 1,200 EUR/month. The most tangible gain: -60 % re-keying and smooth connection to hospital systems.
What an HL7/FHIR integration involves
Interoperability is a project, not a button: identify the flows (admissions, results, reports), map data to FHIR resources, secure exchanges and test with target facilities. Cost depends mostly on the number of flows and source-data quality.
| Item | Content | 2026 range (EUR) |
|---|---|---|
| Flow scoping | Mapping, use cases | 3,000 - 8,000 |
| HL7/FHIR mapping | Transformation, resources | 8,000 - 24,000 |
| Exchange security | Auth, encryption, logging | 4,000 - 12,000 |
| Hospital system connectors | APIs, queues, ETL | 6,000 - 18,000 |
| Interoperability testing | Cross tests with facilities | 3,000 - 9,000 |
| Documentation + compliance | Specs, traceability | 2,000 - 6,000 |
Cost by number of flows and maintenance
Budget rises with the number of flows to connect and how standardized the data is. A clean FHIR flow costs little; a heterogeneous HL7 v2 flow needs more mapping. Here are 2026 orders of magnitude.
| Configuration | Number of flows | 2026 cost (EUR) |
|---|---|---|
| Single standard FHIR flow | 1 | 20,000 - 28,000 |
| Two mixed HL7/FHIR flows | 2 | 28,000 - 40,000 |
| Three to four flows | 3-4 | 40,000 - 52,000 |
| Five flows and more | 5+ | 52,000 - 60,000+ |
| Interoperability maintenance | - | 500 - 1,200 EUR/month |
| Certificates + monitoring | - | 150 - 500 EUR/month |
Mini case study
Liam, CTO of a healthcare software vendor in Dublin, connects his product to 3 hospital systems. His teams manually re-key reports: about 320 hours/month at 32 EUR loaded cost, or 10,240 EUR/month. He invests 46,000 EUR in an HL7/FHIR integration (3 flows) + maintenance 900 EUR/month. By removing 60 % of re-keying, he saves 6,144 EUR/month. Net of maintenance, the gain is 5,244 EUR/month: the integration pays back in under 9 months, while opening sales to facilities that required interoperability.

What does an HL7/FHIR integration cost in 2026?
Between 20,000 and 60,000 EUR depending on the number of flows and data quality. A standard FHIR flow stays around 20-28,000 EUR; five or more flows exceed 52,000 EUR.
What is the difference between HL7 v2 and FHIR?
HL7 v2 is a legacy message format, FHIR is a modern resource-based API. Many projects must handle both, which increases mapping and thus cost.
How long to connect my software?
3 to 6 months depending on the number of flows and facility availability for cross-testing. Interoperability testing is often the longest item.
Can you really cut re-keying by 60 %?
Yes when flows cover admissions, results and reports. Each removed re-keying is also one fewer source of error.
What does maintenance at 500-1,200 EUR/month cover?
Keeping connectors alive, FHIR version evolutions, exchange monitoring and support. Interoperability degrades without upkeep: maintenance is essential.
