The verdict in three sentences
A clinic booking app turns lost slots into honored appointments through an online doctor calendar and automatic SMS/WhatsApp reminders. Result: -35% no-shows and +25% filled slots. For an order of magnitude of 400,000 to 1,200,000 FCFA, with a day-before + 2-hour reminder, a mobile money deposit and a basic patient record, the clinic recovers revenue that is wasted today.
What drives no-shows down
No-shows are not inevitable: they are a reminder and commitment problem. Three levers fix it.
| Lever | Mechanism | Effect |
|---|---|---|
| Day-before reminder | SMS/WhatsApp the night before | -20% no-shows |
| 2-hour reminder | Message 2 h before | -15% more |
| Mobile money deposit | Financial commitment | -30% absences |
| One-tap confirm | Yes/no reply link | Slots freed early |
| Waitlist | Callback list | Cancelled slots refilled |
Combined, these levers move a typical no-show rate from 25-30% to under 15%, which mechanically fills the calendar.
2026 pricing and features
Price depends on the number of doctors and modules (deposit, patient record, waitlist).
| Plan | Price (FCFA) | Contents | Target |
|---|---|---|---|
| Base | 400,000 - 600,000 | Calendar + SMS reminders | 1-2 doctor practice |
| Standard | 600,000 - 900,000 | + MoMo deposit + WhatsApp | Mid-size clinic |
| Advanced | 900,000 - 1,200,000 | + patient record + waitlist | Polyclinic |
| Maintenance | 30,000 - 70,000/mo | Support + reminders included | All |
The mobile money deposit is the strongest lever: a patient who paid a 2,000 FCFA deposit almost always shows up. It is deducted from the consultation fee.

Mini case study
Dr. Ngo, who runs a clinic in Eldoret, has 40 slots/day, average fee 15,000 FCFA, 24 days/month, with 28% no-shows. She installs the Standard plan at 750,000 FCFA.
Before: 40 × 72% honored × 15,000 × 24 = 10,368,000 FCFA/month. With reminders and deposit, no-shows fall to 12%: 40 × 88% × 15,000 × 24 = 12,672,000 FCFA/month. Gain: ~2,304,000 FCFA/month. The app pays for itself in the first week, and a smoother calendar also improves patient satisfaction.
FAQ
Do reminders go by SMS or WhatsApp? Both: WhatsApp when the patient uses it (open rate ~90%), SMS as a fallback to guarantee delivery. The day-before then 2-hour combo is the most effective in 2026.
Is a deposit required to book? Your choice. Making it mandatory cuts no-shows by about 30% but may deter some patients; many clinics reserve it for high-demand slots.
Is the patient record compliant? The Advanced plan includes a basic record (appointment history, notes) with access restricted per doctor. For a clinic, we frame access and data retention from the start.
How long to deploy the app? An order of magnitude of 3 to 5 weeks: setting up doctor calendars, testing reminders, training the front desk. Schedules remain editable by the clinic afterwards.
