The verdict in three sentences
No-shows — guests who book then never come — cost a busy restaurant on average 15 to 25 % of evening revenue. An app with an anti no-show deposit and automatic WhatsApp/SMS reminders drops the absence rate from 22 % to 6 %, while optimising occupancy through a smart floor plan. The result: more covers served, fewer empty tables, and a room running above 90 % occupancy at peak hours.
The real cost of no-shows
A 40-cover restaurant that shows fully booked but suffers 22 % no-shows actually loses 9 covers a night. At an 8,500 FCFA check, that is 76,500 FCFA of revenue gone every evening, or roughly 2,000,000 FCFA a month. Those seats went unsold because they were held until the last minute.
The four levers of a reservation app:
- 24/7 online booking: guests book without calling, even at 11 pm.
- Floor plan: drag-and-drop tables, service management (6 pm, 8 pm, 10 pm).
- Anti no-show deposit: a mobile money deposit of 2,000 to 5,000 FCFA commits the guest.
- Automatic reminders: SMS or WhatsApp the day before and the day of, with a confirmation button.
Costed impact of deposits and reminders (2026 estimate)
| Metric | Without app | With app + deposit | Effect |
|---|---|---|---|
| No-show rate | 22 % | 6 % | -73 % |
| Occupancy rate | 78 % | 90 % | +12 pts |
| Lost covers / night | 9 | 2 | -78 % |
| Off-hours bookings | 0 % | 35 % | new channel |
| Time on the phone | 90 min/day | 20 min/day | -78 % |
| Reminder confirmation rate | — | 82 % | — |
These 2026 orders of magnitude depend on booking volume, but the deposit remains the most effective lever against absenteeism.
What a reservation app costs
| Item | 2026 range | Note |
|---|---|---|
| Reservation app + floor plan | 800,000 - 2,000,000 FCFA | Depends on features |
| Mobile money deposit module | included / 150,000 FCFA | Local wallets |
| SMS reminders | 15 - 25 FCFA / SMS | WhatsApp often free |
| Monthly maintenance | 40,000 - 100,000 FCFA | Support, updates |
| Website + Google widget | included | "Reserve" on your Google listing |
For a restaurant recovering 7 lost covers a night at 8,500 FCFA, the monthly gain exceeds 1,500,000 FCFA: the app pays for itself in one to two months.

Awa runs a 40-seat restaurant in Nairobi that is very busy at weekends. She suffered 22 % no-shows on Friday and Saturday, about 9 lost covers per service at 9,000 FCFA. By introducing a 3,000 FCFA deposit per person and WhatsApp reminders, her no-show rate falls to 6 %. She recovers 7 covers a night, or 63,000 FCFA/night. Over 8 weekend services a month, that is 504,000 FCFA recovered, not counting other nights. The app billed at 1,200,000 FCFA is paid off in roughly two and a half months.
FAQ
Won't a deposit scare guests away?
Not if it is reasonable (2,000 to 5,000 FCFA) and deducted from the bill. Field data shows the booking rate stays stable while no-shows collapse.
How do you handle a guest who cancels in time?
If they cancel within the set window (say 4 hours ahead), the deposit is refunded automatically via the mobile wallet. The rule is transparent from the moment of booking.
Is the floor plan really useful?
Yes. It prevents double-booking the same table and optimises placement by group size, which adds 10 to 15 % occupancy.
Are WhatsApp reminders automatic?
Yes, the day before and the day of, with a one-click confirmation button. Confirmation reaches about 82 %, which further cuts absences.
Can I connect booking to my Google listing?
Yes. A "Reserve" button appears directly on your Google Business profile, capturing guests who find you on Maps.
