The verdict in three sentences
Not every payment should take the same rail: routing by amount and provider sends small baskets where fees are capped and large ones where the success rate is best. Tuned well, it cuts fees by 10 to 18% and lifts success rate by 2 to 4 points in 2026. Here are the concrete rules and the saving calculation.
Why route: fees and reliability are not linear
A provider can be unbeatable on small amounts (fixed or capped fees) and expensive on large ones. Another fails more often above a threshold because of customer account limits. Routing exploits these asymmetries.
| Provider | Small-amount fee | Large-amount fee | Success rate (est.) | Best for |
|---|---|---|---|---|
| Wave | 1.0% | 1.0% | 94-96% | all amounts |
| Orange Money | 1.5% | 2.0% | 90-93% | mid-range |
| MTN MoMo | 1.5% | 1.8% | 89-92% | mid-range |
| Card (PSP) | 2.5% + fixed | 2.8% | 85-90% | large, international |
| M-Pesa (KE) | ~1.5% | capped | 88-93% | Kenya |
The card's fixed fee penalises small baskets; conversely, on a 300,000 FCFA basket a low percentage becomes decisive.
A rules table by bracket
Define amount brackets and, for each, a primary provider plus a fallback on failure. This is the core of orchestration.
| Basket bracket | Primary provider | Fallback 1 | Fallback 2 | Goal |
|---|---|---|---|---|
| < 5,000 FCFA | Wave | MTN MoMo | Orange Money | minimum fee |
| 5,000-50,000 FCFA | Wave | Orange Money | Card | balance |
| 50,000-200,000 FCFA | Wave | Card | Orange Money | reliability |
| 200,000-500,000 FCFA | Card | Wave | Orange Money | account limits |
| > 500,000 FCFA | Card | transfer | Wave | secure collection |
The automatic fallback triggers on failure or timeout: if Wave returns an error, the next provider is offered immediately without the customer leaving the funnel.

Kouame runs a decor store with 6,000,000 FCFA of monthly volume across 500 orders. Before routing, everything went through Orange Money at 2%, i.e. 120,000 FCFA in fees. Routing 65% of volume to Wave at 1% and the rest to card/OM, his average cost drops to about 1.35%, i.e. 81,000 FCFA: a saving of 39,000 FCFA per month, or 468,000 FCFA a year, plus 3 points of success from fewer failures. The routing engine pays for itself in under two months.
FAQ
Does routing complicate the customer experience?
No: the customer sees a simple checkout and, on failure, an automatically offered fallback. All the logic stays server-side, invisible to the buyer.
What realistic saving should I expect?
Between 10 and 18% off your fee bill depending on your current mix and amounts. The more your volume is concentrated on an expensive provider, the bigger the gain.
Does routing really improve the success rate?
Yes, by 2 to 4 points typically, mainly thanks to the automatic fallback that recovers payments which would otherwise fail for lack of a timely alternative.
Do I need several merchant accounts?
Yes, one per provider you want to route to. That is the prerequisite; then the orchestration engine picks the rail according to your bracket rules.
