The verdict in three sentences
At 200 corporate bookings a month, a booking SaaS costs EUR 230 to 610 per month (150,000 to 400,000 FCFA on our Dakar reference grid), but it struggles with deposits, custom quotes and conflicts between rooms and equipment. A custom platform requires EUR 12,200 to 27,400 (8 to 18 million FCFA, about USD 13,200 to 29,700) and 3 to 5 months of development, then pays back in 18 to 30 months against a configured SaaS. The real criterion is not the monthly fee: it is how many bookings are still handled by hand on WhatsApp and spreadsheets.
SaaS, configured SaaS or custom: the three options priced
2026 orders of magnitude for a business renting 6 venues and an equipment fleet (sound, screens, furniture, generators). Prices reflect Kolonell's delivery from Dakar; Dubai-based agencies typically quote 1.5 to 2 times more.
| Criterion | Standard SaaS | Configured SaaS | Custom platform |
|---|---|---|---|
| Setup | EUR 0 to 460 | EUR 2,290 to 4,570 | EUR 12,200 to 27,400 |
| Monthly cost | EUR 230 to 380 | EUR 380 to 610 | EUR 230 to 460 (hosting + maintenance) |
| Local payment methods (cards, wallets, transfers) | Cards mostly | Manual payment links | Native, automatic deposit and balance |
| VAT-compliant quotes and invoices | Generic template | Partial | Complete, numbering and VAT |
| Room + equipment + staff conflicts | Single slot | Simple resources | Combined rules, real-time blocking |
| Time to launch | 1 to 2 weeks | 4 to 8 weeks | 3 to 5 months |
| Data ownership | Vendor, often hosted abroad | Vendor | You, hosting of your choice |
Standard SaaS works below 60 to 80 bookings a month with simple offers. Beyond that, the time spent working around the tool costs more than the subscription.
What custom actually delivers
The features that justify the investment are the ones that hit cash collection and schedule reliability directly.
| Feature | Without a fitting tool | With the custom platform |
|---|---|---|
| Deposit at booking | WhatsApp reminders, 10 to 15% of deposits late | 30 to 50% deposit paid online before the slot is locked |
| Double bookings | 2 to 4% of bookings in conflict | Under 0.2%, automatic blocking |
| Corporate quote | 30 to 45 min per quote | 5 min, price grid and per-client discounts |
| Key account purchase orders | Manual re-keying | Client portal with history and invoices |
| Equipment logistics | Paper list | Check-out and return slip per event |
| Dashboard | Spreadsheet updated on Fridays | Real-time occupancy and revenue |
Key accounts (banks, NGOs, embassies) often require a purchase order, a compliant invoice and payment by bank transfer. The custom platform runs all three flows while keeping instant mobile payment for smaller clients.
Timeline and project steps
A typical project runs 3 to 5 months: 2 weeks of scoping, 3 weeks of mock-ups validated with the sales team, 8 to 12 weeks of development, then 3 weeks of testing with real bookings. Migrating client history from spreadsheets takes 3 to 5 days. Plan one day of training for sales staff and event managers.

- Configured SaaS: EUR 3,810 setup and EUR 580 per month, plus about EUR 305 per month of admin time to reconcile payments by hand, so EUR 885 per month.
- Custom platform: EUR 18,300 (about USD 19,800), then EUR 320 per month for hosting and maintenance.
- Monthly gap: 885 - 320 = EUR 565. Extra upfront cost: 18,300 - 3,810 = EUR 14,490. Payback: 14,490 / 565 = about 26 months.
- Uncounted bonus: double bookings drop from 6 to under 1 a month, about EUR 760 of goodwill gestures avoided each month.
Including that last gain, payback falls below 12 months.
FAQ
How much does a custom B2B booking platform cost?
Budget EUR 12,200 to 27,400 (USD 13,200 to 29,700) depending on the number of resources, pricing rules and integrations (payments, accounting). Hosting and maintenance then add EUR 230 to 460 per month.
Isn't an international SaaS enough?
For fewer than 80 bookings a month with simple pricing, yes, at EUR 230 to 380 per month. But many handle neither split deposits nor key account purchase orders, and their invoices rarely match local VAT rules.
How do we prevent double bookings?
The platform checks combined availability of venue, equipment and staff in real time, and only locks the slot once the deposit is paid. Conflicts fall below 0.2% of bookings.
Can deposits be collected online?
Yes, card and wallet integrations allow a 30 to 50% deposit paid online with automatic confirmation. In West Africa, the same platform plugs into Wave and Orange Money at around 1% fees.
How long until it pays off?
Against a configured SaaS, payback sits between 18 and 30 months. Counting avoided double bookings and unpaid deposits, it often drops below 12 months.
