The verdict in three sentences
Custom management software for a medical group practice in Montpellier costs between 30,000 and 50,000 EUR excl. VAT in 2026, excluding health-data hosting. Certified HDS hosting (2,000 to 5,000 EUR/year) and health GDPR compliance are not optional: they are legal prerequisites. The value of custom is the integrated multi-practitioner calendar and third-party payment, where vertical solutions impose their limits.
The budget module by module in 2026
Ranges for a practice of 5 to 12 practitioners in Montpellier (2026 order of magnitude).
| Module | Scope | Cost EUR excl. VAT |
|---|---|---|
| Multi-practitioner calendar | Booking, rooms, shared schedules | 6,000 |
| Patient record (HDS) | History, prescriptions, documents, timeline | 12,000 |
| Teleconsultation | Secure video, virtual waiting room | 5,000 |
| Billing & third-party payment | Care sheets, third-party payment, exports | 7,000 |
| Patient portal | Online booking, reminders, documents | 4,000 |
| Interoperability | Gateways, health-standard exports | 4,000 |
| Training & go-live | Data migration, training, go-live | 4,000 |
A calendar + patient record + billing core runs about 30,000 EUR excl. VAT; adding teleconsultation, the portal and interoperability pushes the total toward 45,000 to 50,000 EUR excl. VAT.
Recurring costs and compliance
Beyond development, plan for the annual costs tied to health data (2026 estimate).
| Recurring item | Annual range |
|---|---|
| Certified HDS hosting | 2,000 - 5,000 EUR/yr |
| Maintenance & upgrades | 3,600 - 6,000 EUR/yr |
| Backups & DRP | 1,000 - 2,500 EUR/yr |
| Support & on-call | 1,200 - 3,000 EUR/yr |
| GDPR & security audit | 1,500 - 3,000 EUR/yr |
HDS hosting is a regulatory obligation as soon as you process personal health data: it is the first item to secure.
Mini case study
Dr Sanchez coordinates an 8-practitioner practice in Montpellier. Before, the front desk handled ~180 calls/day for appointments, with a no-show rate of 14%. By deploying a patient portal with automatic reminders (4,000 EUR excl. VAT) plus a multi-practitioner calendar (6,000 EUR excl. VAT), no-shows drop to 6%. Across 8 practitioners doing 20 acts/day at 30 EUR, recovering 8 points of no-show is about 384 EUR/day, more than 90,000 EUR/year of recaptured slots. The 30,000 EUR investment pays back in under 5 months.

FAQ
Is HDS hosting really mandatory?
Yes, as soon as you store or process personal health data on behalf of others, hosting must be HDS-certified. Budget 2,000 to 5,000 EUR/year depending on volume.
What delivery timeline?
Budget 16 to 22 weeks for a calendar + patient record + billing scope, due to security requirements and compliance testing.
Does the software handle third-party payment?
Yes: care-sheet generation, third-party payment management and exports to insurers. Rules are configured with your administrator.
Can teleconsultation be integrated?
Yes, with secure video and a virtual waiting room. The module costs around 5,000 EUR excl. VAT and meets health confidentiality requirements.
How to guarantee interoperability with the health ecosystem?
By relying on exchange standards (HL7/FHIR) and standard exports. This avoids lock-in and eases future connections.
