The verdict in three sentences
A private clinic loses money on two invisible fronts: missed appointments and poorly optimised practitioner schedules. Market health SaaS (60 to 200 EUR/user/month) cover booking but struggle to fold billing, third-party payment and records into a single flow. Custom development between 45,000 and 95,000 EUR, hosted on HDS-certified infrastructure, aligns all these modules and cuts no-shows by 30%.
Health SaaS or custom: the tipping point
Health data hosting (HDS in France) is mandatory as soon as patient data is involved: it's not an option but a foundation. The question is how far your tool must fit your care pathways.
| Criterion | Health SaaS | Custom |
|---|---|---|
| Cost | 60 to 200 EUR/user/month | 45,000 to 95,000 EUR once |
| Annual cost (25 users) | 18,000 to 60,000 EUR | Maintenance 9,000 to 16,000 EUR |
| HDS hosting | Depends on vendor | Included and contractual |
| Practitioner scheduling | Standard | Rules per specialty |
| Third-party payment | Often an add-on | Built into billing flow |
| Appointment reminders (SMS/email) | Limited | Custom scenarios |
The scope of clinic software
Value lies in online booking, multi-practitioner scheduling, billing with third-party payment and the patient record. Automated reminders are the direct lever on no-shows.
| Module | Content | 2026 range (EUR) |
|---|---|---|
| Online booking + reminders | Calendar, SMS/email, waitlists | 12,000 to 22,000 |
| Multi-practitioner scheduling | Rooms, resources, specialties | 10,000 to 20,000 |
| Billing + third-party payment | Procedures, insurers, follow-ups | 10,000 to 22,000 |
| Secure patient record | History, documents, rights | 10,000 to 20,000 |
| HDS hosting + compliance | Infrastructure, backups | 6,000 to 14,000 |
Allow a 14 to 22 week timeline, HDS hosting and record migration included.
Mini case study
Dr Lefèvre runs a 25-practitioner private clinic in Nice. The no-show rate is 12% across around 4,500 monthly appointments, i.e. 540 lost slots. Valuing a slot at 45 EUR net margin, that's 24,300 EUR lost per month, close to 291,600 EUR a year. An automated reminder system cutting no-shows by 30% recovers 87,000 EUR a year. The custom investment of 80,000 EUR pays back in under twelve months.
