The verdict in three sentences
A payment gateway's fees are not just the commission: you must add the fixed fee per transaction and the payout/settlement fees, which weigh heavily on small baskets. Integration costs 2.5 to 8 M FCFA (3,810-12,200 EUR) in 3 to 7 weeks, at a daily rate of 250,000 to 450,000 FCFA. The most profitable 2026 lever is multi-gateway routing: sending each transaction to the cheapest channel lowers the average rate without changing the customer experience.
Breaking down the cost lines
A headline 2.5% rate often hides a higher real cost once fixed and payout fees are included. Example across baskets, at 2.5% + 100 FCFA fixed + 0.5% settlement:
| Basket | Commission | Fixed fee | Settlement | Real cost |
|---|---|---|---|---|
| 5,000 FCFA | 125 | 100 | 25 | 5.0% |
| 20,000 FCFA | 500 | 100 | 100 | 3.5% |
| 50,000 FCFA | 1,250 | 100 | 250 | 3.2% |
| 150,000 FCFA | 3,750 | 100 | 750 | 3.1% |
| 500,000 FCFA | 12,500 | 100 | 2,500 | 3.0% |
On small amounts, the fixed fee dominates: hence the value of grouping orders or routing micro-payments to mobile money.
Multi-gateway routing to lower the average rate
By connecting several gateways behind a single layer, you route each payment to the optimal channel. Typical gains:
| Lever | Effect on average rate | Setup cost |
|---|---|---|
| Card vs mobile money routing | -0.4 to -0.8 pt | 1-2.5 M FCFA |
| Volume negotiation with gateway | -0.2 to -0.5 pt | included |
| Auto failover on decline | +2-4% success rate | 0.5-1.2 M FCFA |
| Tokenization (recurring clients) | -0.1 to -0.3 pt | 0.6-1.5 M FCFA |
| PCI security & anti-fraud | -unpaid/disputes | 0.8-2 M FCFA |
Maintenance runs 250,000 to 700,000 FCFA/month: monitoring, PCI updates and dispute handling.

Mini case study
Serge, head of a B2B office-supplies SME in Cotonou, collects 180 M FCFA/year online, average basket 35,000 FCFA (≈5,143 orders), at an average real cost of 3.2%, i.e. 5.76 M FCFA/year in fees. By deploying multi-gateway routing and steering small baskets to mobile money, he brings the real cost to 2.4%, i.e. 4.32 M FCFA: a saving of 1.44 M FCFA/year. The 5 M FCFA integration + 400,000 FCFA/month maintenance pays back in about three years, with the higher success rate (auto failover) adding extra revenue.
FAQ
Why does my real cost exceed the headline rate? Because fixed and settlement fees add to the commission. On a 5,000 FCFA basket, the real cost can reach 5% despite a 2.5% headline.
Is multi-gateway routing complex? It requires an abstraction layer, but it's a 1 to 2.5 M FCFA investment that pays off every month. It also avoids vendor lock-in.
Is PCI compliance mandatory? As soon as you touch card data, yes. Using a certified gateway and tokenization sharply reduces your PCI scope and therefore cost.
How do we reduce B2B unpaid invoices? 3-D Secure, tokenization and anti-fraud reduce disputes. For large clients, credit limits remain the best risk-control tool.
How long is integration? 3 to 7 weeks for 2.5 to 8 M FCFA, depending on the number of gateways, security and reconciliation required.
