The verdict in three sentences
A mobile money deposit at booking turns a free, no-commitment appointment into a slot the patient has a real reason to honor. In practice, clinics see a no-show drop of 15 to 25 points within the first weeks, reclaiming slots that used to be wasted. The app pays for itself in under six months for a busy practice.
Paper diary vs booking app with deposit
The average practice's problem isn't a lack of patients: it's the patient who grabs a slot by phone and never shows. With no financial stake, cancelling costs nothing. A Wave, Orange Money or M-Pesa deposit of 2,000 to 5,000 FCFA changes the psychology.
| Criterion | Paper diary / phone | Booking app + momo deposit |
|---|---|---|
| No-show rate | 25 to 40 % | 8 to 15 % |
| Double booking | Frequent | Eliminated (locked slots) |
| Patient reminder | Manual, forgotten | Automatic SMS + WhatsApp D-1 and D-0 |
| Deposit collected | 0 FCFA | 2,000 to 5,000 FCFA / appt |
| Reconciliation | By hand, at night | Automatic, real time |
| Patient history | Notebook | Searchable database |
The automatic reminder matters as much as the deposit: a patient warned the day before on WhatsApp cancels in time, freeing the slot for someone else. Together these two levers drive the no-show collapse.
App cost and time to launch
A booking app with deposit sits in the advanced Vitrine tier or a health SaaS module. 2026 orders of magnitude in Senegal and Côte d'Ivoire:
| Item | 2026 order of magnitude |
|---|---|
| Booking + deposit app (build) | 500,000 to 1,200,000 FCFA |
| Shared SaaS version / month | 15,000 to 40,000 FCFA |
| Time to launch | 5 to 15 days |
| Momo fee on deposit | 1 to 2 % of amount |
| SMS reminders | 10 to 25 FCFA / SMS |
| WhatsApp reminders | Near zero (Cloud API) |
The practice sets the deposit amount: a GP often uses 2,000 FCFA, a specialist or dentist 5,000 FCFA, deducted from the final consultation.
Mini case study
Dr Fatou, a dermatologist in Dakar, runs 12 patients a day, 22 days a month, roughly 264 monthly appointments. With the paper diary, her no-show sits at 30 %: nearly 79 lost slots a month. At an average 15,000 FCFA consultation, that's 1.18 million FCFA of revenue evaporating.
After the app with a 3,000 FCFA deposit, her no-show falls to 10 %, or 26 lost slots. She recovers 53 extra honored slots per month, about 795,000 FCFA in added revenue. The app cost 900,000 FCFA: paid back in just over a month, then pure gain.

FAQ
How much does a booking app with deposit cost in 2026?
Expect 500,000 to 1,200,000 FCFA for a dedicated build, or 15,000 to 40,000 FCFA per month for a shared SaaS version. Launch takes 5 to 15 days.
How much does no-show actually drop?
Practices see a 15 to 25 point drop: a 30 % rate typically falls to around 10 %. The deposit and the D-1 WhatsApp reminder work together.
What deposit amount should I ask for?
Between 2,000 and 5,000 FCFA, deducted from the consultation. A GP often uses 2,000 FCFA, a specialist 5,000 FCFA. Too low and the deterrent vanishes.
Is the patient refunded on a timely cancellation?
You set the rule: automatic refund if cancelled more than 24 h ahead, deposit kept otherwise. Momo refunds take a few minutes via the API.
Do patients need to download a mobile app?
No. A web app opened from a WhatsApp link is enough and works on 3G. It avoids install friction and store costs.
