The verdict in three sentences
Without a deposit, a restaurant suffers roughly 22 % no-shows on its bookings, emptying reserved tables in the middle of service. A simple 5 000 FCFA deposit paid via mobile money cuts that rate to 6 % and lifts table turnover by 18 %. For a build cost of around 800 000 FCFA, the return on investment lands within three months.
The real cost of a no-show
An empty table that should have been filled is margin lost for good: the evening service never replays. For a 40-cover restaurant with an average ticket of 12 000 FCFA, each unreplaced no-show costs a full cover plus the food already prepped.
| Metric | Without deposit | With 5 000 FCFA deposit |
|---|---|---|
| No-show rate | 22 % | 6 % |
| Covers lost / night (of 40) | 8.8 | 2.4 |
| Table turnover | Base | +18 % |
| Average ticket | 12 000 FCFA | 12 000 FCFA |
| Margin lost / night | 63 000 FCFA | 17 000 FCFA |
| SMS reminder D-1 | No | Yes |
The deposit plays two roles: it commits the customer psychologically and it funds part of the cover even in case of a no-show. Deducted from the final bill, it is neutral for the honest guest.
What the app does
The app covers the whole journey: online booking, deposit payment via mobile money (Wave, Orange Money, M-Pesa in Nairobi), automatic confirmation and an SMS reminder 24 h before. The manager sees the floor plan in real time and blocks saturated slots.

Mini case study
Awa runs a 40-cover restaurant in Dakar, open 26 nights a month. Before the app, her 22 % no-shows cost roughly 63 000 FCFA of margin per night, or 1.64 million FCFA per month. With the deposit, the loss drops to 17 000 FCFA per night, or 442 000 FCFA per month: a saving of 1.2 million FCFA monthly. The 800 000 FCFA app is therefore paid back in under three weeks of net gain, well inside the three-month window.
FAQ
Do customers really accept paying a deposit? Yes, when the deposit is modest (5 000 FCFA) and deducted from the bill. Venues that display it clearly see no-shows fall from 22 % to 6 % with no meaningful drop in booking volume.
What happens with a legitimate cancellation? The app lets guests cancel free of charge up to a set deadline (for example 4 h before). After that, the 5 000 FCFA deposit is retained, which stays fair on both sides.
How much do the SMS reminders cost? About 15 FCFA per SMS. For 300 bookings a month that is 4 500 FCFA, negligible against the 1.2 million FCFA of recovered margin.
Should Wave and Orange Money both be integrated? Yes, offering both (plus M-Pesa in Nairobi) maximises deposit conversion. A single payment method loses the customers who don't use that wallet.
How long does the app take to deliver? A solid base is built in 3 to 5 weeks for around 800 000 FCFA, with the mobile money deposit, floor plan and SMS reminders live from launch.
