The verdict in three sentences
For a store selling in 2026, a single aggregator keeps things simple: one integration, one webhook, one reconciliation. Per-transaction fees are slightly higher (1.8% versus 1% to 1.7% direct), but development cost drops from 1,050,000 FCFA to 450,000 FCFA. Unless you have high volume and can negotiate operator rates, the aggregator wins on total first-year cost.
Fees and settlement: the 2026 benchmark
The rates below are 2026 orders of magnitude for an e-commerce merchant. Direct operator fees are often negotiable above 5,000,000 FCFA of monthly volume.
| Solution | Merchant fee | Settlement | Transaction cap | Integration |
|---|---|---|---|---|
| Rail A direct | 1.0% | T+2 | 2,000,000 FCFA | 350,000 FCFA |
| Rail B direct | 1.5% | T+2 | 2,000,000 FCFA | 350,000 FCFA |
| Rail C direct | 1.7% | T+3 | 1,500,000 FCFA | 350,000 FCFA |
| Aggregator | 1.8% | T+2 | 2,000,000 FCFA | 450,000 FCFA |
Going direct, you stack three integration projects (3 x 350,000 = 1,050,000 FCFA), three key sets, three webhooks to maintain. The aggregator gives you a single technical contract covering all rails.
The hidden cost: maintenance and checkout failures
A mobile money checkout fails on average in 6% of cases (expired OTP, insufficient balance, lost callback). Each operator has its own retry logic. More integrations means more points of failure.
| Item | 3 direct integrations | 1 aggregator |
|---|---|---|
| Initial dev | 1,050,000 FCFA | 450,000 FCFA |
| Maintenance/yr (estimate) | 300,000 FCFA | 120,000 FCFA |
| Webhooks to monitor | 3 | 1 |
| Checkout failure rate | 6% | 6% |
| Time to launch | 6 weeks | 2 weeks |
On transaction fees alone, for 3,000,000 FCFA of monthly sales, the 1.8% vs 1.3% average gap costs 15,000 FCFA/month, or 180,000 FCFA/year. That is less than the 600,000 FCFA saved on dev plus maintenance in year one.

Mini case study
Koffi runs a cosmetics store, 4,000,000 FCFA in monthly sales. Direct, he pays 1,050,000 FCFA of dev once. Via the aggregator: 450,000 FCFA. Monthly aggregator fees at 1.8% = 72,000 FCFA/month (864,000 FCFA/year). Direct at 1.3% average = 52,000 FCFA/month (624,000 FCFA/year). Fee gap: 240,000 FCFA/year. But Koffi saves 600,000 FCFA in year one on dev plus maintenance: he is still ahead by 360,000 FCFA in year 1, then switches to direct if he passes 6,000,000 FCFA/month.
FAQ
Which rail has the biggest market share? The two leading rails dominate merchant payments in 2026, with a third following. An aggregator covers all three at once, so you avoid betting on a single one.
Is the 2,000,000 FCFA per-transaction cap a blocker? Rarely in consumer e-commerce. For B2B, split the payment or request a raised-cap merchant profile from the operator.
How long until I get paid? Settlement is T+2 for most rails and the aggregator, T+3 for one operator. Expect 2 to 3 business days between the sale and available funds.
Can I negotiate the aggregator's 1.8%? Yes, above 5,000,000 to 10,000,000 FCFA of monthly volume, rates drop. Below that, public pricing applies.
Do I still need Stripe? Only if you sell internationally. For a purely local market, mobile money is enough and cheaper than cards.
