The verdict in three sentences
A car wash with no booking suffers peak-hour queues and captures no recurring revenue. An app with booking slots and a monthly unlimited-wash subscription turns one-off revenue into a predictable flow and lifts customer lifetime value by 30 to 50%. The choice is between a custom app (900,000 to 2,800,000 FCFA) and a SaaS (10,000 to 35,000 FCFA/month).
Custom or SaaS: the 2026 cost
The pay-per-wash model lets the loyal customer slip away and clogs the station on Saturdays. Here is the 2026 order of magnitude for a station with 2 to 4 bays in Accra.
| Criterion | No app | Car-wash SaaS | Custom app |
|---|---|---|---|
| Upfront cost | 0 FCFA | 0 to 120,000 FCFA | 900,000 to 2,800,000 FCFA |
| Monthly cost | 0 FCFA | 10,000 to 35,000 FCFA | Hosting 12,000 FCFA |
| Booking slots | No | Yes | Yes, custom |
| Unlimited-wash subscription | No | Partial | Yes, native |
| Mobile Money payment | No | Yes | Yes, native wallets |
| Loyalty program | No | Basic | Yes, custom |
| Data ownership | You | The vendor | You |
The SaaS launches the subscription fast. The custom app makes sense once the station wants its own brand, several subscription tiers and a loyalty program tied to its client list.
What the subscription changes
The monthly subscription guarantees revenue even on quiet days and pushes the customer to come more often since each extra visit is already paid for.
| Indicator | Before (pay-per-wash) | After (app + subscription) |
|---|---|---|
| Peak-hour waiting time | 25 min | 8 min |
| Share of subscribed customers | 0% | 35% |
| Monthly recurring revenue | 0 FCFA | 1,400,000 FCFA |
| Visit frequency per month | 1.4 | 2.6 |
| Customer lifetime value (12 months) | 42,000 FCFA | 63,000 FCFA |
| Return-customer rate | 30% | 58% |
Slot booking smooths the crowd: the customer picks a time, the queue shrinks and the station handles more vehicles per day.

Within three months, 35% of his regulars subscribe, about 95 subscribers generating 1,425,000 FCFA in monthly recurring revenue. Visit frequency rises from 1.4 to 2.6 per month and the investment pays back in one month of recurring revenue.
