The verdict in three sentences
The no-show is the restaurant's invisible theft: a booked table that never shows is a cover sold to nobody. A reservation system with SMS/WhatsApp reminders and a Wave deposit drops no-shows from 22-28% to under 8%. For a 90-seat restaurant, that means about 7M FCFA of recovered revenue per year and weekend utilization climbing from 68% to 85%.
Paper book vs digital system
Phone bookings written in a notebook have a structural problem: no reminder, no commitment, no visibility on table turnover. The digital system fixes all three.
| Criterion | Notebook / phone | Digital system |
|---|---|---|
| No-show rate | 22 - 28% | < 8% |
| Automatic reminder | no | SMS/WhatsApp D-1 and H-2 |
| Deposit / commitment | no | Wave 2,000-5,000 FCFA/cover |
| Table-turn visibility | none | real time |
| Friday/Saturday utilization | 68% | 85% |
| Customer history | lost | full customer DB |
The simple H-2 reminder already eliminates most forgotten bookings; the deposit turns a reservation into a real commitment, especially on weekends.
Cost and quantified gains in 2026
Here is the 2026 order of magnitude to deploy a reservation system versus the revenue recovered.
| Item | 2026 range |
|---|---|
| Reservation module | 250,000 - 700,000 FCFA |
| SMS reminder cost | 15 - 25 FCFA / message |
| Wave deposit (optional) | 2,000 - 5,000 FCFA / cover |
| Wave fee on deposit | 1 - 1.5% |
| Average recovered ticket | ~9,000 FCFA / cover |
If the system recovers 15 no-show covers per week at 9,000 FCFA, that's 135,000 FCFA/week, i.e. about 7M FCFA/year, for a marginal SMS cost of a few thousand francs per month.

Mini case study
Adjovi, manager of a 90-seat restaurant in Nairobi, suffered a 25% weekend no-show. On 60 covers booked Friday and Saturday, that was ~15 lost covers/week at 9,000 FCFA, i.e. 135,000 FCFA/week gone. She invests 450,000 FCFA in a reservation module with SMS reminders and a 3,000 FCFA/cover Wave deposit.
Result: no-shows fall under 8%, she recovers ~12 covers/week. Gain: 12 x 9,000 = 108,000 FCFA/week, i.e. ~5.6M FCFA/year. SMS cost (60 reminders x 2 x 20 FCFA = 2,400 FCFA/week) is negligible. The module pays back in about 4 weeks, and weekend utilization rises from 68% to 85%.
FAQ
How much does an anti no-show reservation system cost in 2026? Budget 250,000 to 700,000 FCFA for the module, plus 15 to 25 FCFA per SMS reminder; the Wave deposit is optional (2,000-5,000 FCFA/cover).
How much does the no-show rate drop? With automatic reminders and a deposit, it falls from 22-28% to under 8%, on our 2026 assumptions for a high-traffic weekend restaurant.
Does the Wave deposit scare off customers? No, a moderate deposit of 2,000 to 5,000 FCFA/cover, deducted from the bill, is well accepted on weekends and turns the booking into a commitment.
How much revenue does a restaurant recover? A 90-seat restaurant recovering ~15 no-show covers/week at 9,000 FCFA recovers on the order of 7M FCFA/year.
Does the system improve table turnover? Yes: real-time visibility on free tables raises Friday/Saturday utilization from 68% to 85%.
