The verdict in three sentences
A marketplace that refunds blindly ends up paying with money it never held back — and an unhappy vendor blocks everything. Two models clash: the immediate refund (fast but risky, the money is already paid to the vendor) and escrow + claim window (money stays held until the dispute period ends). In 2026, with an average dispute rate of 3-5% and a 7-day window, only a 5% guarantee reserve makes refunds funded and painless.
Immediate refund versus escrow with window
The core problem: if you pay the vendor at order time, a later refund forces you to claw the money back — often in vain. Escrow reverses the logic.
| Criterion | Immediate refund | Escrow + claim window |
|---|---|---|
| Vendor payment timing | At order | After the 7 days |
| Source of refund | Platform cash | Funds still held |
| Vendor debt risk | High | None |
| Buyer trust | Fragile | Solid |
| Refund delay | Immediate | T+0 to T+2 after decision |
| Fit for mobile money | No | Yes |
2026 parameters of a refund policy
A clear policy prices every delay and every hold. The values below are 2026 orders of magnitude for the Senegalese market.
| Parameter | 2026 value | Effect |
|---|---|---|
| Dispute window | 7 days | Time to file a claim |
| Average dispute rate | 3 to 5% | Volume to provision |
| Wave/OM refund delay | T+0 to T+2 | After arbitration decision |
| Non-refunded provider fees | 1% | Dead loss to arbitrate |
| Vendor guarantee reserve | 5% | Funds the refunds |
| Target amicable resolution rate | 80% | Without formal arbitration |
| Vendor response deadline | 48 h | Otherwise default decision |
The trap of non-refunded 1% provider fees: on a refunded 20,000 FCFA basket, the 200 FCFA of Wave/OM fees are lost. Decide in advance who bears them — platform or at-fault vendor.

- Opening: the buyer files the dispute within 7 days, with evidence.
- Vendor notification: 48 h to respond, otherwise a default decision favoring the buyer.
- Amicable resolution: target 80% of cases settled here (partial refund, reshipment).
- Platform arbitration: in case of disagreement, decision on evidence.
- Execution: Wave/OM refund (T+0 to T+2), debited from the vendor's reserve.
Mini case study
Fatou runs a fashion marketplace in Senegal, 1,000 orders/month averaging 18,000 FCFA. With a 4% dispute rate, she handles 40 monthly disputes, i.e. ~720,000 FCFA potentially refunded. Thanks to escrow, no refund leaves her cash: funds come from the still-held vendor share or the 5% reserve. Of those 40 disputes, 32 (80%) resolve amicably. Lost provider fees (~1% on executed refunds) amount to about 7,200 FCFA for the month — a controllable, budgeted cost.
FAQ
Should you refund immediately to reassure the buyer? No: immediate refunds expose you to unrecoverable vendor debts. Escrow with a 7-day window protects everyone and is still perceived as fast (T+0 to T+2 after decision).
Who bears the 1% non-refunded provider fees? To define in your terms. In 2026 the norm is the vendor if the dispute is their fault, the platform otherwise. On 20,000 FCFA it stays ~200 FCFA.
What does the 5% guarantee reserve cover? It funds refunds without touching your cash. Held before each payout, it is released to the vendor after the dispute window if no claim is opened.
What if the vendor does not respond? After 48 h with no reply, the default decision favors the buyer. This rule pushes vendors to act fast and feeds the 80% amicable resolution rate.
How do you keep the dispute rate at 3-5%? Precise product sheets, real photos, displayed delivery times and visible vendor ratings. Upstream transparency mechanically reduces disputes.
