The verdict in three sentences
For a services SME in West Africa, a payment aggregator lets you accept cards and mobile money under a single contract, for 1.5% to 3.5% per transaction depending on payment method and volume. The full cost of integrating it into a customer portal runs 800,000 to 2,500,000 FCFA (about USD 1,400 to 4,300), including automated accounting reconciliation. The deciding factor is not only the headline fee but settlement time, withdrawal fees and webhook quality, and Stripe is not an option for a merchant incorporated in Benin.
The context of a Beninese services SME
Take an IT maintenance and security company in Cotonou with 25 staff and 140 business customers on annual contracts. Invoices of 150,000 to 2,000,000 FCFA are paid by bank transfer or cheque, with an average delay of 52 days. The manager wants a portal where customers see their invoices and pay in one click via MTN MoMo, Moov Money, Celtiis Cash or Visa and Mastercard, without signing separate contracts with each operator.
| Criterion | Beninese aggregator (FedaPay, KkiaPay) | Regional aggregator (CinetPay, PayDunya) | Pan-African (Flutterwave) | Stripe |
|---|---|---|---|---|
| Mobile money fee | 1.5% to 2.5% | 2% to 3% | 2% to 3.5% | Not supported |
| Card fee | 2.5% to 3.5% | 3% to 3.5% | About 3.5% | 2.9% + 30 cents (US entity) |
| Beninese operators covered | MTN, Moov, Celtiis | MTN, Moov | MTN, Moov | None |
| Settlement time | D+1 to D+2 | D+1 to D+3 | D+2 to D+3 | D+2 (supported countries) |
| Merchant KYC | 1 to 2 weeks | 2 to 3 weeks | 2 to 3 weeks | Requires a foreign entity |
| WAEMU multi-country coverage | Benin, Togo, Côte d'Ivoire, Senegal depending on plan | 8 to 10 countries | 30+ countries | No WAEMU entity |
| Withdrawal fee to bank account | 0 to 0.5% | 0 to 1% | Varies by currency | FX fees 1% to 2% |
These rates are 2026 ballpark figures, negotiable above 20 to 30 million FCFA collected per month. Always check the contractual grid before signing.
What integration costs
The aggregator provides the API, but it still has to be wired properly into your portal and accounting. 2026 ballpark in Cotonou:
| Component | Content | Indicative budget | Timeline |
|---|---|---|---|
| Simple payment button | Payment link per invoice | 800,000 FCFA (about USD 1,400) | 1 to 2 weeks |
| Customer portal integration | Invoice list, payment, PDF receipt | 1,500,000 FCFA (about USD 2,600) | 3 to 4 weeks |
| Webhooks and failure handling | Confirmation, retry, partial payment | Included or 300,000 FCFA | 1 week |
| Automated accounting reconciliation | Export to Sage or Odoo, matching | 500,000 to 700,000 FCFA | 2 weeks |
| Dual aggregator (failover) | Switch if one is down | 400,000 FCFA | 1 week |
| Full portal total | All components | 2,000,000 to 2,500,000 FCFA (USD 3,400 to 4,300) | 5 to 7 weeks |
Reconciliation is the most profitable item: without it, the accountant spends 2 to 3 days a month working out which MoMo payment matches which invoice.
Pitfalls to avoid
First pitfall: comparing only the rate. An aggregator at 1.8% that settles at D+3 and charges 1% on withdrawals costs more than a competitor at 2.2% settling at D+1 with no fee. Second pitfall: ignoring webhooks. A mobile money payment can stay pending for several minutes, and a portal that does not handle that status shows failure to a customer who has actually been debited. Third point: merchant KYC requires the RCCM trade register entry, IFU tax number, articles of association, manager's ID and bank details. Prepare them before development starts to avoid losing 3 weeks.

Firmin, manager of the Cotonou services company, collects 45,000,000 FCFA a month. He targets 40% online payments, or 18,000,000 FCFA, 80% via mobile money at 2% and 20% by card at 3%. Monthly fees: 14,400,000 x 2% + 3,600,000 x 3% = 288,000 + 108,000 = 396,000 FCFA. Full integration: 2,200,000 FCFA. In return, the average payment delay drops from 52 to 20 days on that 18,000,000 FCFA. With a bank overdraft at 11% a year, 32 days saved are worth about 174,000 FCFA a month, plus 2 days of accounting work saved, about 120,000 FCFA. Above all, the freed cash avoids an extra 19,000,000 FCFA credit line.
FAQ
Do we need a contract with each mobile money operator?
No, that is the whole point of an aggregator: one contract covers MTN MoMo, Moov Money and often Celtiis Cash. KYC takes 1 to 3 weeks depending on the aggregator.
Can the fee be passed on to the customer?
It is contractually possible in B2B, but it slows adoption. Most SMEs absorb 2% in exchange for being paid 30 days faster.
What if the aggregator goes down?
With a second aggregator configured for about 400,000 FCFA, the portal switches automatically. Outages rarely last more than a few hours but often hit at month end.
Are international cards accepted?
Yes, most aggregators accept foreign Visa and Mastercard, at a higher fee, often 3.5% to 4%.
How long until we are live?
Plan 5 to 7 weeks for a full portal, KYC included, if documents are ready from day one.
