The verdict in three sentences
A vertical health SaaS (Doctolib Pro, Weda, Maiia and US equivalents) is cheap to start but its price scales with your provider count and locks you into its data model. Custom software requires 45,000 to 120,000 EUR up front, but becomes profitable once you pass 8 to 10 providers and want scheduling, EHR and billing in a single flow. In both cases, certified compliant hosting is not optional: it is a legal requirement costing 400 to 1,200 EUR/month.
What each option costs in 2026
The health software market is built around per-provider licenses. Here are 2026 orders of magnitude for a mid-sized private clinic.
| Item | Vertical SaaS | Custom |
|---|---|---|
| License / development | 90-350 EUR/month/provider | 45,000-120,000 EUR |
| Certified compliant hosting | included or 200-500 EUR/month | 400-1,200 EUR/month |
| GDPR/HIPAA compliance setup | 1,000-3,000 EUR | 4,000-9,000 EUR |
| Staff training | 500-2,000 EUR | 2,000-5,000 EUR |
| Maintenance (support) | included | 12-18 %/year |
| Time to go live | 2-6 weeks | 4-7 months |
SaaS wins on speed and initial cost. Custom wins on data control, no per-provider fee, and the ability to model your real processes (specific care pathways, complex insurance billing, third-party payment).
Total cost over 3 years, the only metric that matters
Compare a 12-provider clinic. SaaS at 180 EUR/month/provider costs 180 x 12 x 36 = 77,760 EUR over 3 years, before options and price hikes. Custom at 85,000 EUR plus support at 15 % (12,750 EUR/year) comes to 85,000 + 38,250 = 123,250 EUR, hosting on top.
| Scenario (12 providers) | 3-year cost | Avg cost/provider/month |
|---|---|---|
| SaaS 180 EUR/month | 77,760 EUR | 180 EUR |
| SaaS 250 EUR/month | 108,000 EUR | 250 EUR |
| Custom 85,000 EUR + support | 123,250 EUR | 285 EUR |
| Custom + hosting (800 EUR/month) | 152,050 EUR | 352 EUR |
Over 3 years SaaS is often cheaper for a small practice. Custom is justified only for specific flows the market does not cover, or a high headcount where per-provider pricing becomes punitive.
Mini case study
Laurent, director of a 9-provider private medical center, paid 210 EUR/month per provider on a SaaS, i.e. 22,680 EUR/year. His front-desk staff lost 12 hours/week re-entering appointments between the non-integrated calendar and billing. Moving to custom software at 72,000 EUR (compliant hosting at 600 EUR/month included the first year), he captures the 12 h/week gain (about 15,600 EUR/year of staff time) and eliminates double entry. Estimated payback: 34 months, after which he only pays support (10,800 EUR/year) versus 22,680 EUR in subscription.

FAQ
Is compliant hosting really mandatory?
Yes. Any personal health data must sit on a certified host (HDS in France, HIPAA-compliant in the US). Non-compliance exposes you to fines up to 4 % of annual revenue under GDPR or heavy HIPAA penalties.
Can I migrate my data from my current SaaS?
Yes, but budget 3,000 to 8,000 EUR for export, cleaning and re-import. Check your SaaS contract includes a reversibility clause with export in a standard format.
How long to build custom software?
Plan 4 to 7 months for a mid-sized clinic, with a functional MVP (scheduling + EHR) deliverable in 3 months, then billing and advanced modules by iteration.
Is custom compliant by default?
No, compliance is built: processing register, encryption, consent management, certified hosting. Budget 4,000 to 9,000 EUR for initial GDPR/HIPAA setup.
What productivity gain can I expect?
Clinics that integrate scheduling, records and billing into a single flow save on average 8 to 15 hours/week of front-desk time, a full part-time role in a 10-provider practice.
