The verdict in three sentences
An online booking module integrated with practitioner calendars costs 8,000 to 25,000 EUR custom, or 30 to 120 EUR/month as health SaaS in 2026. The real gain is not the website: it is the 20-40 % cut in no-shows from SMS reminders and the drop in phone-call volume. For a mid-sized clinic, payback is measured in months, not years.
Anatomy of a booking module that works
A good module does more than display slots. It syncs each practitioner's calendar in real time, sends automated reminders, handles cancellations and re-lists freed slots. Here are the building blocks and their cost.
| Function | Custom cost 2026 (EUR excl. tax) | SaaS equivalent |
|---|---|---|
| Real-time slot engine | 3,000 - 7,000 | included |
| Automated SMS + email reminders | 2,000 - 5,000 | 0.05 - 0.09 EUR/SMS |
| Practitioner calendar integration | 2,000 - 6,000 | included/API |
| Cancellation + waiting list | 1,500 - 4,000 | add-on |
| Patient portal (account, history) | 3,000 - 8,000 | included |
SaaS launches faster; custom prevails as soon as you need to match specific scheduling rules (variable duration per act, shared resources, technical platform).
ROI: front-desk time freed
The most visible line item is phone time. A receptionist often spends 2-3 hours a day handling appointments. Here is the one-year impact for a mid-sized clinic.
| Metric | Before | After (with online booking) |
|---|---|---|
| Booking calls/day | 60 | 25 |
| Front-desk hours/day on booking | 3.0 | 1.2 |
| No-show rate | 18 % | 11 % |
| Lost appointments/month (1,500 base) | 270 | 165 |
| Value of lost appointments (55 EUR/act) | 14,850 EUR/mo | 9,075 EUR/mo |
That is about 5,775 EUR/month recovered on no-shows, plus 1.8 hours/day of front-desk time redeployed. The module typically pays for itself in 3-6 months.

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Ms Fall, medical director of a 12-practitioner clinic in Dakar, invests 16,000 EUR in a custom booking module with SMS reminders. Before: 18 % no-shows on 1,400 monthly appointments. After: 10 %, i.e. 112 no-shows avoided per month. At 45 EUR average act, that recovers 5,040 EUR/month, plus 1,000 EUR in fewer calls. Investment repaid in 3 months, and two half-time receptionists reassigned to physical reception.
FAQ
How long to set up online booking?
Between 2 and 4 months custom, or 2-4 weeks in SaaS. Integrating with the existing calendar is the item that lengthens the timeline.
Do SMS reminders really cut no-shows?
Yes: 2026 studies show a 20-40 % drop depending on the population. A D-2 and an H-3 reminder deliver the best results.
Does the module connect to our current software?
Yes via API in most cases. Budget 2,000-6,000 EUR to integrate with the practitioner calendar and EHR.
Do we need HDS hosting for a simple booking module?
As soon as you store data identifying a patient and a reason for consultation, HDS hosting applies. Expect 300-600 EUR/month for a small scope.
