The verdict in three sentences
A custom medical booking platform costs in 2026 between 40 000 and 110 000 EUR, versus a monthly or per-appointment commission charged by intermediary platforms. The real gain is not just escaping that commission: it is the 20 to 35 % no-show reduction driven by automated SMS reminders. For a health group beyond 15 practitioners, bringing it in-house pays off in 12 to 24 months.
Build cost vs intermediary commission
Third-party platforms charge either a per-practitioner subscription or a per-appointment commission. At high volume, the cumulative bill quickly exceeds the cost of owning a platform.
| Scenario | Intermediary model | Custom platform |
|---|---|---|
| Upfront cost | 0 EUR | 40 000 - 110 000 EUR |
| Monthly cost (20 practitioners) | 1 800 - 3 600 EUR | 400 - 900 EUR (host+maint.) |
| 3-year cost | 65 000 - 130 000 EUR | 55 000 - 140 000 EUR |
| Ownership of patient data | No | Yes |
| Journey customization | Limited | Full |
| Brand | Third party | Yours |
Beyond roughly 15-20 practitioners, the 3-year cost tips in favor of an owned platform, while recovering patient data and brand.
The no-show effect: the real ROI
The missed appointment is a practice's quietest source of loss. Automated reminders cut it sharply.
| Lever | Without platform | With automated reminders |
|---|---|---|
| Average no-show rate | 12 - 22 % | 6 - 12 % |
| SMS reminder D-1 | Manual/absent | Automatic |
| Email reminder D-2 | No | Automatic |
| One-click rescheduling | No | Yes |
| Freed slots re-filled | No | Auto waitlist |
| No-show reduction | — | -20 to -35 % |
For a clinic handling 8 000 appointments/month at 45 EUR average value, moving from 15 % to 9 % no-show recovers roughly 21 600 EUR/month of value.

Mini case study
Dr Sarr coordinates a 22-practitioner group in Lyon. The group was paying 2 900 EUR/month to a third-party platform, i.e. 34 800 EUR/year. It invests 68 000 EUR in its own platform (multi-practitioner scheduling, SMS reminders, waitlist) plus 700 EUR/month of operations. In the first year alone, saved commission plus the no-show drop (from 16 % to 10 %) generate over 90 000 EUR of recovered value. Payback in under 12 months.
FAQ
What do reminder SMS cost? Budget 0.04 to 0.08 EUR per SMS. For 8 000 appointments/month with two reminders, that is 640 to 1 280 EUR/month, easily offset by the no-show drop.
Can we keep our existing practice software? Yes, the booking platform connects to the EHR via API. Budget 6 000 to 14 000 EUR for calendar synchronization.
How long until launch? Between 3 and 5 months for a full version with reminders and automatic waitlist.
Will patients adopt online booking? Yes: depending on the practice, 40 to 70 % of appointments shift online within 6 months, easing the phone desk accordingly.
Do we need healthcare hosting? If the platform stores medical data, yes, certified healthcare hosting applies and adds 6 000 to 20 000 EUR/year.
