The verdict in three sentences
International PMS software charges 50 to 200 EUR/month plus OTA commissions, and stays poorly suited to Senegalese mobile payment. A custom hotel management app (PMS) costs 2,000,000 to 4,500,000 FCFA once, with no monthly subscription, and bundles room planning, a Booking/Airbnb channel manager and Wave deposits. For a 10-40 room hotel in Saly, the real win is anti-overbooking: zero double-booking, so no lost nights and no upset guests.
Foreign SaaS PMS vs custom app
The maths shift fast once you reason over 3 to 5 years rather than the entry ticket.
| Criterion | Foreign SaaS PMS | Kolonell custom app |
|---|---|---|
| Upfront cost | Low (often 0) | 2,000,000 - 4,500,000 FCFA |
| Subscription | 50 - 200 EUR/month | 0 (optional maintenance) |
| 5-year cost | 3,000 - 12,000 EUR | 2,000,000 - 4,500,000 FCFA |
| Wave/OM payment | rare or absent | native |
| Channel manager | yes (paid option) | included |
| Local fit | weak | total |
| Data | hosted abroad | under your control |
Over 5 years, a 120 EUR/month subscription is roughly 4,700,000 FCFA, more than a custom app you own outright.
The real cost of overbooking
A double-booking is not just a lost night: it is a relocation, a bad review and a lost guest.
| Consequence of an overbooking | 2026 estimate (FCFA) |
|---|---|
| Night to relocate elsewhere | 25,000 - 60,000 |
| Last-minute relocation surcharge | 15,000 - 40,000 |
| Bad review (booking impact) | hard to quantify, high |
| Goodwill gesture (discount) | 10,000 - 30,000 |
| Average cost per incident | 50,000 - 130,000 |

At 2-3 incidents/month in high season, that is 100,000 to 400,000 FCFA/month avoided by a synced channel manager.
Mini case study
Mr Diallo runs a 24-room hotel in Saly. He paid a foreign PMS 130 EUR/month (~85,000 FCFA) and suffered 2 double-bookings/month in season, about 160,000 FCFA in losses. A custom app at 3,200,000 FCFA removes the subscription and the overbooking: he saves 85,000 + 160,000 = 245,000 FCFA/month in high season. Payback in roughly 13 to 18 months, after which the tool costs nothing.
FAQ
Does the channel manager really prevent all double-booking? Yes: as soon as a room is booked on any channel (Booking, Airbnb, direct site), it is blocked everywhere in real time. The risk drops to near zero as long as sync runs.
Can I collect a deposit via Wave? Yes, the app generates a Wave/Orange Money payment link for the deposit at the time of direct booking, with automatic confirmation. This secures the night and cuts cancellations.
What happens to my data if I leave a foreign PMS? With a custom app, the data stays yours and hosted to your requirements; we plan the import of your booking history during migration.
Do I need a permanent connection? The channel manager needs internet to sync, but viewing the planning and data entry work locally and resync afterwards. An outage does not block the front desk.
