The verdict in three sentences

Choosing a payment gateway is not about the headline rate, but about the total cost relative to your average basket and your settlement delays. In 2026, budget 2.5 to 3.2% card commission, FCFA 500 to 1,500 per transfer and FCFA 2,000,000 to 6,000,000 for technical integration. For online revenue of FCFA 50,000,000 a year, the gap between two PSPs can reach several hundred thousand FCFA.

Understanding the fee structure

A gateway rarely bills a single line. You must add variable commission, fixed per-transaction fees, integration cost and settlement delay (which ties up cash).

Item2026 order of magnitude
Card commission2.5% - 3.2% of amount
Fixed fee per transactionFCFA 100 - 300
Bank transferFCFA 500 - 1,500 / transaction
Technical integrationFCFA 2,000,000 - 6,000,000
Settlement delayT+2 to T+7
Refund feeFCFA 0 - 500 / operation

Total cost by volume

For online revenue of FCFA 50,000,000 a year, the bill varies mostly with the card rate and the number of transactions.

In B2B, steering large amounts toward transfer rather than card noticeably reduces the variable commission.

Mini case study

Sarah, CFO of a wholesaler in London, does FCFA 50,000,000 online with a FCFA 100,000 average basket, i.e. 500 transactions/year. At 100% card and 3%, she pays FCFA 1,500,000 + FCFA 150,000 fixed fees = FCFA 1,650,000/year. Shifting 40% of volume to transfer (FCFA 1,000/transaction) drops the bill to ~FCFA 1,200,000/year, i.e. FCFA 450,000 saved. The FCFA 3,500,000 integration pays back much faster once you factor in fewer defaults and reconciliation automation.

FAQ

Is the lowest commission rate always the best?

No. A low rate paired with high fixed fees costs more on small baskets. Simulate total cost against your real volume and average basket.

How much is technical integration?

Between FCFA 2,000,000 and 6,000,000 in 2026 depending on complexity (simple payment, tokenization, recurring payment, automatic reconciliation).

What settlement delay should I target?

T+2 is ideal for cash flow; T+7 ties up more funds. For FCFA 50,000,000 revenue, each day of delay ties up about FCFA 137,000 on average.

How do I handle defaults and refunds?

Choose a PSP with a refund module and dispute handling. Refund fees range from FCFA 0 to 500 per operation depending on the provider.

Can we combine multiple gateways?

Yes, and it is recommended: an international card gateway plus a local transfer solution optimizes cost by order type.
