The verdict in three sentences
For a B2B business, whether run from New York or from an Abidjan subsidiary, that collects from clinics in Senegal, Mali, Burkina Faso and Côte d'Ivoire, the right answer is almost always a combination: a local aggregator for mobile money and cards, plus bank transfer with a unique reference for large amounts. Fees range from 1.5 to 3.5% per transaction, but the real gap between two gateways lies in limits, payout delay and the ability to match each payment to its invoice automatically. A full integration costs FCFA 1.5 to 4 million (about USD 2,500 to 6,700) depending on payment methods and accounting automation.
Fees and terms of payment options in 2026
The table compares the main solution families available to a B2B merchant collecting in the WAEMU zone. Rates are 2026 orders of magnitude, negotiable with volume. Note that local aggregators generally require a locally registered entity, which is why most US companies collect through a subsidiary or a distributor in Abidjan.
| Option | Fee per transaction | Limit per payment | Payout | WAEMU countries covered |
|---|---|---|---|---|
| Local aggregator (mobile money + card) | 1.5 to 3.5% | FCFA 1 to 2 M by mobile money, higher by card | 1 to 3 days | 4 to 8 countries |
| Wave Business (direct) | About 1% | Depends on payer profile | Same day to 1 day | Senegal, Côte d'Ivoire, Mali, Burkina Faso |
| Orange Money merchant | 1 to 2% | FCFA 1 to 3 M by country | 1 to 2 days | 4 to 5 countries |
| Card via international gateway | 2.9 to 3.5% plus fixed fees | High | 2 to 7 days | All, card only |
| Bank transfer with unique reference | FCFA 0 to 5,000 per transfer | No practical limit | 1 to 3 days (regional clearing) | All 8 countries |
| Payment link sent on WhatsApp | Aggregator fees | Aggregator limits | 1 to 3 days | Depends on aggregator |
For clinic orders of FCFA 500,000 to 5,000,000 (USD 830 to 8,300), mobile money limits often block large amounts: the site must switch to bank transfer automatically above a threshold.
The B2B features the gateway must support
A B2B site does not work like a consumer store. Clinic buyers ask for a proforma invoice, pay in installments and need compliant documents for their accounting.
| B2B feature | Why it matters | Indicative integration cost |
|---|---|---|
| Proforma PDF generated from the cart | Required for internal purchase approval | FCFA 300,000 to 600,000 |
| Partial payment (deposit then balance) | Equipment orders worth millions | FCFA 400,000 to 800,000 |
| Payment link per invoice | Easy follow-up on outstanding amounts | FCFA 200,000 to 400,000 |
| Automatic payment-to-invoice matching | No more manual entry in accounting | FCFA 500,000 to 1,200,000 |
| Webhooks with retry on failure | No order confirmed without confirmed payment | FCFA 300,000 to 600,000 |
| SYSCOHADA accounting export | Entries ready for the accountant or software | FCFA 200,000 to 400,000 |
The sum of these modules explains the FCFA 1.5 to 4 million range: a simple project covers one aggregator and webhooks, a full one covers everything.
How to compare two aggregators without mistakes
Ask for a simulation on your real volumes rather than a public rate card. Check four points: withdrawal fees to your bank account, often overlooked, the availability of a full sandbox, the quality of webhook documentation, and a commercial contact in Abidjan. Also request the list of countries where payouts are made in FCFA with no FX fee, which is the case across the whole WAEMU zone. If funds must reach a US account, add the cost of the FCFA to USD conversion, typically 1 to 2%.

David, CFO of a New York medical equipment company selling through its Abidjan subsidiary, books FCFA 1.2 billion (about USD 2 million) of online sales per year to clinics in four countries. Moving from a card gateway at 3.2% to a mix of local aggregator at 2% for 40% of the amounts and bank transfer for 60%, fees drop from FCFA 38.4 million to about FCFA 9.6 million, plus FCFA 1.8 million in transfer fees: FCFA 28 million saved per year (about USD 46,700). Automatic reconciliation also frees an accountant two days a week, about FCFA 4 million per year. A full integration at FCFA 3.2 million pays back in under 2 months.
FAQ
Do we need an entity in every WAEMU country to collect?
No, an aggregator based in Côte d'Ivoire usually lets you collect in several countries of the zone, in FCFA and with no FX fee. You do need at least one locally registered entity, and should check the exact operators covered per country.
How do we handle an FCFA 5 million order?
Above the mobile money limit, the site automatically offers bank transfer with a unique reference, or a mobile money deposit followed by a transfer for the balance. Matching runs on the reference.
How long does gateway integration take?
Plan 3 to 5 weeks for an aggregator with webhooks and proforma, and 6 to 8 weeks for the full scope with partial payment and SYSCOHADA export.
Are fees negotiable?
Yes, above FCFA 50 million of monthly volume, aggregators often drop by 0.5 to 1 point. Prepare your last 12 months of volumes before negotiating.
How do we avoid orders confirmed without payment?
An order moves to paid only after the webhook is received and its signature verified. A scheduled job also queries the API every 15 minutes for pending payments.
