The verdict in three sentences
A generic POS records the bill but smooths neither the kitchen nor the margins. A custom app (mobile order taking, kitchen display KDS, at-table mobile money payment, stock and per-dish margin tracking) costs 1.5 to 4 M FCFA and cuts errors from 5-10 % to under 2 %. For a high-volume restaurant, the faster service and lower waste pay for the app within a few months.
Generic POS vs custom app
| Criterion | Generic POS | Custom app |
|---|---|---|
| Kitchen transmission | Paper ticket | Real-time kitchen display (KDS) |
| Order errors | 5 to 10 % | Under 2 % |
| At-table payment | Counter only | Wave / Orange Money at table |
| Margin tracking | None | Per dish, real time |
| Stock management | Manual | Auto decrement per sale |
| Service time | Standard | Reduced (prioritised KDS) |
Quantified impact on service and margins
| Indicator | Before app | After app (est.) |
|---|---|---|
| Order error rate | 8 % | 2 % |
| Average service time | 28 min | 20 min |
| Covers served/service | 90 | 110 |
| Waste / stock losses | 6 % | 3 % |
| At-table payment share | 0 % | 40 % |
Fewer errors = fewer remade and comped dishes; faster service = more covers at the same capacity. App cost: 1.5 to 4 M FCFA, maintenance 50,000 to 150,000 FCFA/month.
Key app features
The waiter takes the order on mobile; it appears instantly on the kitchen display (KDS), organised by station (hot, cold, bar) and prioritised. The guest can pay at the table via Wave/Orange Money. The app decrements stock on each sale, alerts on shortages, and computes the per-dish margin to identify the most profitable recipes. The manager tracks revenue per service in real time.

Mini case study
Awa's restaurant serves 100 covers/service, average check 9,000 FCFA, 2 services/day. At 8 % error, about 8 dishes/service are remade or comped, a loss of around 72,000 FCFA/day. The app brings errors to 2 % and speeds service: the loss falls to 18,000 FCFA/day (saving 54,000 FCFA/day) and capacity rises to 110 covers. Over 300 days, the error saving alone exceeds 16,000,000 FCFA/year. The app at 3,000,000 FCFA + maintenance pays back in 2 to 3 months.
FAQ
Does the kitchen display replace paper tickets? Yes. Orders appear in real time by station, with a timer per dish. No more lost or illegible tickets, and the kitchen instantly sees the service priorities.
Is at-table payment secure? Yes. The guest scans a QR code at their table and pays via Wave or Orange Money; the bill is marked paid automatically, reducing till errors and counter queues.
How does the app track margins? Each dish has a recipe and a food cost. On each sale, the app computes the real margin, letting you adjust the menu and promote the most profitable dishes.
Does it work during an internet outage? Yes, in offline mode: orders continue locally and sync when the network returns, essential given frequent outages.
