The verdict in three sentences
To cut missed appointments and unclog the phone line, a practice has two options in 2026: a booking SaaS at 30-120 EUR/month or custom software at 12,000-30,000 EUR. Custom is justified as soon as you have several practitioners, complex slot rules or integration with your patient record. In both cases, SMS reminders are lever number one: they lower no-shows by ~25 % and free up to 15 front-desk hours per month.
SaaS vs custom: the 2026 comparison
SaaS is fast and cheap to start; custom becomes profitable as the practice grows and needs get specific.
| Criterion | Booking SaaS | Custom |
|---|---|---|
| Entry cost | 30 - 120 EUR/month | 12,000 - 30,000 EUR once |
| Setup time | 1 - 2 weeks | 6 - 10 weeks |
| Multi-practitioner calendar | Standard | Tailored (rooms, resources) |
| SMS reminders | Often a paid add-on | Built in, unlimited |
| Patient record integration | Rare | Native |
| Customization | Low | Total |
| 3-year cost (est.) | 1,100 - 4,300 EUR | 12,000 - 33,000 EUR |
Below two practitioners, SaaS almost always suffices. Beyond that, or if you want control over your data and to remove growing monthly fees, custom takes over.
The real cost of SMS reminders
SMS reminders are the operational line item not to overlook: they drive much of the ROI and vary by volume.
| Monthly volume | Unit SMS cost (est. 2026) | Monthly cost |
|---|---|---|
| 200 SMS | 0.07 EUR | 14 EUR |
| 500 SMS | 0.06 EUR | 30 EUR |
| 1,000 SMS | 0.055 EUR | 55 EUR |
| 2,000 SMS | 0.05 EUR | 100 EUR |
| 5,000 SMS | 0.045 EUR | 225 EUR |
In custom builds, these reminders are integrated into the calendar and triggered automatically (48 h and 2 h before the appointment), with a confirmation or cancellation link that immediately recycles the freed slot.

Mini case study
Dr. Martin shares a 3-doctor practice in Lyon. They handle around 1,200 appointments/month with 18 % no-shows, i.e. 216 lost slots. At an average consultation of 35 EUR, that is 7,560 EUR/month of lost revenue.
They commission a custom booking module at 18,000 EUR, with built-in SMS reminders. No-shows fall to 13.5 % (a 25 % reduction), recovering 54 slots/month, i.e. 1,890 EUR/month. Adding 15 saved front-desk hours (valued at ~300 EUR), the monthly gain approaches 2,190 EUR. The investment pays back in about 8 to 9 months.
FAQ
Isn't a SaaS enough to start? Often yes, for one or two practitioners. Custom becomes relevant when monthly fees climb, when you want to integrate the patient record or customize slot rules.
Do SMS reminders really reduce no-shows? Yes, a double reminder (48 h and 2 h before) typically cuts absences by 20 to 30 %, with a cancellation link that puts the slot back online automatically.
Can I integrate booking with my existing software? In custom builds, yes: synchronization with the patient record, cashier or an existing calendar via API. It is one of the main advantages over SaaS.
How long until it's operational? Budget 6 to 10 weeks for custom, including practitioner, room and reminder configuration, plus a short team training.
Can patients book online 24/7? Yes, via a portal or a widget on your site: the patient picks a slot, gets a confirmation and can cancel themselves, freeing the front-desk phone.
