The verdict in three sentences
An appointment booking app cuts no-shows by 30 % by combining automatic SMS reminders with a 5,000 FCFA deposit paid via mobile money at booking. Development costs between 900,000 and 4,500,000 FCFA depending on the tier, paid back in 4 to 9 months through recovered slots. For a Lagos clinic running 40 patients/day, it turns a paper diary into a chair-filling machine.
Why no-shows are so expensive
In Lagos, a missed appointment is not just an empty box: it is a doctor's slot paid for but never billed, a waiting patient who never got the spot, and a receptionist who spends the morning on the phone. An average consultation billed at 15,000 FCFA lost 12 times a week is 720,000 FCFA/month vanishing.
The mobile money deposit changes patient psychology: once you have committed 5,000 FCFA via a mobile wallet, you either show up or cancel early to get refunded. The 24-hour SMS reminder does the rest.
| Lever | Without app | With app |
|---|---|---|
| No-show rate | 28 % | 8 % |
| Patient reminders | Manual, random | Auto SMS D-1 and H-2 |
| Booking deposit | None | 5,000 FCFA mobile money |
| Front-desk time/day | 4 h on phone | 2 h |
| Slots recovered/week | 0 | 10 to 14 |
| Estimated monthly gain | — | 500,000 to 700,000 FCFA |
Features and development cost by tier
There is no point paying for modules the clinic will not use in year one. Here is our 2026 grid (ballpark) by facility size.
| Tier | Key features | Dev cost | Target |
|---|---|---|---|
| Essential | Online diary, SMS reminders, 1 practitioner | 900,000 FCFA | Solo practice |
| Growth | Multi-practitioner, mobile money deposit, light patient record | 2,200,000 FCFA | 3-6 doctor clinic |
| Premium | Teleconsultation, analytics, till integration, patient app | 4,500,000 FCFA | Polyclinic |
| Recurring | Hosting + SMS + maintenance | 75,000 FCFA/month | All tiers |
The SMS line item is real: budget 25 to 35 FCFA per SMS; for 40 patients/day that stays under 40,000 FCFA/month, easily covered by avoided no-shows.

Mini case study
Dr Konan runs a 4-doctor clinic. Before the app: 200 appointments/week, 28 % no-shows, i.e. 56 lost slots valued at 15,000 FCFA = 840,000 FCFA/week of theoretical lost revenue, of which roughly a third is truly recoverable.
After rolling out the Growth tier (2,200,000 FCFA): no-shows fall to 8 %, i.e. 16 lost slots. He therefore recovers 40 slots/week, of which he conservatively re-bills 15 = 225,000 FCFA/week or 900,000 FCFA/month. The app pays for itself in under three months, on top of the 2 hours/day of front-desk time redirected to reception.
FAQ
How long does development take? Budget 3 to 5 weeks for the Essential tier, 6 to 9 weeks for the Growth tier with mobile money deposit. The Premium tier with teleconsultation needs 10 to 14 weeks.
Does the 5,000 FCFA deposit discourage patients? On the contrary: it is deducted from the consultation and refunded on 24-hour cancellation. Clinics typically see the no-show rate drop by 20 points in the first month.
Can several mobile wallets run at once? Yes, a unified payment module handles the main mobile wallets. The patient picks their operator at booking; operator fees run around 1 to 1.5 %.
What happens during an internet outage? The app works in degraded mode: the receptionist reads the cached diary and syncs once the network returns. SMS reminders go out from the server, independent of the clinic's connection.
Is it compliant with health data protection? Patient data is encrypted and hosted with role-based access. We apply data minimisation and consent principles, aligned with the personal data protection frameworks in force locally.
