The verdict in three sentences
Mobile money has no automatic chargeback like a bank card: refunding a customer means initiating an outbound transfer at your cost. Depending on the method, the refund takes T+0 to T+2 and costs 0 to 2 %. With a West African e-commerce dispute rate of 2 to 4 %, you need a cash reserve of 5 to 8 % of revenue to never run dry.
API refund vs manual transfer
Two approaches exist: reverse via the PSP's API, or manual transfer from your merchant account. The first scales, the second doesn't.
| Criterion | API refund (reverse) | Manual operator transfer |
|---|---|---|
| Delay | T+0 to T+2 | T+0 to T+1 |
| Fees borne | Often 0 % (reverse) | 1 to 2 % |
| Automatable | Yes | No |
| Traceability | Full (webhook) | Manual |
| Error risk | Low | High (wrong number) |
| Volume handled | High | Low |
API reverse (Wave, Paystack) is almost always preferable: traceable, often free, and automatable in your back office. Manual transfer is only justified for isolated cases.
Costs, disputes and cash reserve
The figures below are 2026 estimates to adjust for your sector and PSP.
| Item | 2026 order of magnitude |
|---|---|
| West African e-commerce dispute rate | 2 to 4 % of orders |
| Manual refund fee | 1 to 2 % of amount |
| Wave/Paystack reverse API delay | T+0 to T+2 |
| Recommended return window | 7 to 14 days |
| Advised cash reserve | 5 to 8 % of monthly revenue |
| Target support handling time | < 48 h |
A return window of 7 to 14 days and support handling under 48 h limit disputes that escalate to operators or social media.
Mini case study
Mariama runs a ready-to-wear shop in Dakar, revenue 5,000,000 FCFA/month. Her dispute rate is 3 %, i.e. 150,000 FCFA/month to refund. Via manual transfer at 1.5 %, she loses 2,250 FCFA in fees and 2 hours of work. Switching to fee-free reverse API, she saves those fees and automates the process. She sets aside a reserve of 6 % of 5M = 300,000 FCFA to absorb return peaks without ever blocking a refund, protecting her reputation and reviews.
