The verdict in three sentences
A no-show patient means a lost, non-billable doctor slot: without reminders, 20 to 30 % of appointments evaporate. An online booking app paired with automated SMS reminders brings that rate down to 8-12 % and fills the gaps through an auto waitlist. The return on investment lands within weeks, even for a small clinic.
The real cost of no-shows
Every empty slot is not just wasted time: it is a consultation that will never be billed, plus a waitlist patient who could have been treated. An SMS reminder costs a few shillings; a no-show costs thousands.
| Metric | No app, no reminder | With app + dual SMS |
|---|---|---|
| No-show rate | 20-30 % | 8-12 % |
| Phone call load | 100 % (baseline) | -40 % |
| Slots filled / day (20 slots) | 14-16 | 18-19 |
| Cost of one reminder SMS | — | 15-25 FCFA |
| Waitlist backfill | Manual | Auto |
| MoMo deposit at booking | Impossible | 2,000-5,000 FCFA |
What the app does
The mechanic is simple but powerful: the patient books alone, gets two reminders, and optionally pays a deposit that locks in the visit.
| Feature | Measurable effect |
|---|---|
| 24/7 online booking | -40 % front-desk calls |
| SMS reminder at 24h | -50 % no-shows on its own |
| SMS reminder at 2h | Catches last-minute forgetters |
| Auto waitlist | Fills a cancellation in < 15 min |
| MoMo deposit (Wave/Orange) | Near-zero no-shows on paid slots |
| Doctor dashboard | Day view + fill rate |
Mini case study
Take Dr Aminata, a gynecologist in Nairobi, 20 slots/day at 15,000 FCFA equivalent. At 25 % no-shows she loses 5 slots, or 75,000 FCFA/day. After the app, no-shows fall to 10 %: she loses only 2 slots (30,000 FCFA). Net gain: 45,000 FCFA/day, roughly 1,170,000 FCFA/month (26 days). The SMS cost? 20 patients x 2 reminders x 20 FCFA = 800 FCFA/day. The math speaks for itself.

How much does sending reminder SMS cost?
Budget 15 to 25 FCFA per SMS depending on the carrier in 2026. For 20 patients/day with two reminders, that is under 900 FCFA/day, negligible against the consultations recovered.
Is the mobile money deposit really useful?
Yes: on slots with a 2,000-5,000 FCFA deposit via Wave or Orange Money, the no-show rate drops near zero. A patient who has paid almost always shows up.
Will my older patients manage online booking?
The front desk keeps classic phone booking; the app mainly absorbs connected patients and frees the switchboard. Both channels feed the same calendar.
What happens on a cancellation?
The waitlist automatically offers the freed slot to the next patient by SMS, often filled in under 15 minutes instead of staying empty.
How long to deploy the app?
A standard clinic is live in 2 to 4 weeks: calendar, SMS reminders and MoMo payment included.
