The verdict in three sentences
For a B2B platform operating in Benin, Togo and Ivory Coast, choosing a gateway depends less on the headline rate than on three criteria: coverage of local payment methods in each country, a payout delay of D+1 to D+3 and the quality of the reconciliation data returned by the API. Aggregator fees range from 1.5 to 3.5% in 2026 and can be negotiated below 2% above 100 million FCFA collected a month. Budget 3 to 8 million FCFA (4,570 to 12,200 EUR) with a West African team, or roughly 40,000 to 90,000 GBP with a London fintech agency, for a clean integration with automatic per-country reconciliation, otherwise your finance team will spend every month-end ticking statements.
Payment methods to cover, country by country
A pharmacy in Lomé does not pay like a pharmacy in Abidjan. A gateway that covers Benin well but Ivory Coast poorly will force you to plug in a second one, with two contracts and two statement formats.
| Country | Dominant mobile money | Other expected B2B methods | Watch point |
|---|---|---|---|
| Benin | MTN MoMo, Moov Money | Bank transfer, card | Check mobile money limits for large baskets |
| Togo | Yas (formerly T-Money), Moov Money | Transfer, card | Coverage varies across aggregators |
| Ivory Coast | Orange Money, MTN MoMo, Wave, Moov Money | Transfer, card, cheques still common | Wave requires its own integration with some aggregators |
| Senegal (expansion) | Wave, Orange Money, Free Money | Transfer, card | Plan it in the architecture if expansion is 18 months away |
| All WAEMU countries | BCEAO interoperability (PI-SPI) being rolled out | Regional instant transfer | Track its opening to aggregators |
Gateway comparison criteria in 2026
Three families coexist: regional aggregators born in Benin or Ivory Coast, pan-African players and bank card gateways. The figures below are 2026 orders of magnitude observed on B2B contracts.
| Criterion | Regional WAEMU aggregator | Pan-African player | Bank gateway (cards) |
|---|---|---|---|
| Standard fees | 1.5 to 3% | 2 to 3.5% | 1.8 to 3% + fixed fees |
| Negotiated fees above 100M FCFA per month | 1.2 to 1.8% | 1.5 to 2.5% | 1.5 to 2.2% |
| Payout delay | D+1 to D+2 | D+2 to D+3 | D+2 to D+5 |
| Benin, Togo, Ivory Coast coverage | Good to very good | Varies by country | Cards only |
| Reconciliation data | Merchant reference, webhooks | Full API reports | Bank statements, often PDF |
| Partial payment and cash-out fees | Often possible | Depends on plan | Rarely |
Integration and reconciliation budget
| Component | Content | Budget (FCFA excl. VAT) | Timeline |
|---|---|---|---|
| One gateway integration | Payment, signed webhooks, status and failure handling | 1,500,000 to 3,000,000 | 3 to 5 weeks |
| Backup second gateway | Automatic failover if the first is down | 1,000,000 to 2,000,000 | 2 to 3 weeks |
| Automatic reconciliation | Matching payment, invoice and payout, flagged discrepancies | 1,000,000 to 2,500,000 | 3 to 4 weeks |
| Per-country accounting reconciliation | Journals per entity, local VAT (18% in Benin, Togo and Ivory Coast), export to accounting software | 800,000 to 1,500,000 | 2 to 3 weeks |
| Treasury dashboard | Collections, fees and expected payouts per country | 500,000 to 1,000,000 | 1 to 2 weeks |
| Typical total | One or two gateways, full reconciliation | 3,000,000 to 8,000,000 | 8 to 14 weeks |
Mini case study
Serge, founder in Cotonou of an ordering platform for 320 pharmacies across Benin, Togo and Ivory Coast, processes 384,000,000 FCFA of orders a month, 40% of which are paid by mobile money or card, i.e. 153,600,000 FCFA. His current aggregator charges 2.5%. By negotiating 1.8% with a regional aggregator with better coverage, he saves 0.7%, or 1,075,200 FCFA a month. Automatic reconciliation frees an accountant who spent 3 days a month per country ticking statements, worth about 400,000 FCFA a month. Total gain: nearly 1,475,000 FCFA a month (about 2,250 EUR). For a full integration at 6,000,000 FCFA, payback comes in just over 4 months.

FAQ
What fees should we expect for a WAEMU payment gateway in 2026?
Budget 1.5 to 3.5% per transaction depending on the aggregator and payment method. Above 100 million FCFA collected a month, a rate of 1.2 to 1.8% is negotiable.
Is one gateway enough for three countries?
It can be if it covers MTN MoMo and Moov in Benin, Yas and Moov in Togo, plus Orange Money, MTN and Wave in Ivory Coast. A backup gateway, at 1 to 2 million FCFA, secures peaks and outages.
Can we use Stripe from Cotonou or London?
Stripe does not open merchant accounts in WAEMU countries in 2026 and does not cover local mobile money. A London-registered entity can use it only to collect card payments from international customers.
How do we avoid gaps between payments and invoices?
Each payment must carry the invoice's unique reference and be confirmed by a signed webhook. A reconciliation module costing 1 to 2.5 million FCFA automatically flags amount or fee discrepancies.
How fast does the money reach the account?
From D+1 to D+3 depending on the gateway and country, sometimes D+5 for cards. That delay must appear in your per-country treasury dashboard.
