The verdict in three sentences
Mobile money payment fraud accounts for 1 to 4 % of transactions in West African e-commerce, mostly via fake receipts and screenshots sent over WhatsApp. The only reliable defense is to verify the real payment status on the PSP side (Wave, Orange Money) before shipping, never on the strength of a screenshot. Too many rules kill conversion: the goal is to block fraud without adding friction for the 96-99 % of honest customers.
Fraud schemes and their defenses
Most fraud exploits the fact that many merchants approve an order on a simple payment screenshot, without checking the transaction at the source.
| Fraud scheme | How it works | Defense |
|---|---|---|
| Fake receipt / doctored screenshot | Edited image of a non-existent payment | Verify status via PSP API/USSD |
| Payment cancelled after screenshot | Screenshot sent, then transaction cancelled | Ship only on confirmed "success" |
| Triangulation | Payment from a stolen third-party account | Cross-check payer name / customer name |
| Abusive refund | "Never received" on a delivered parcel | Signed delivery proof + photo |
| Overpayment then difference request | Overpays, claims a refund | Refund only on the same channel |
Anti-fraud rules vs customer friction
Every added control reduces fraud but can scare off customers. The right setting depends on average basket and observed fraud rate.
| Anti-fraud measure | Fraud reduction (2026 est.) | Added friction |
|---|---|---|
| Automatic PSP status check | High | None (invisible to customer) |
| SMS OTP confirmation | Medium | Low |
| Threshold before manual review | Medium | Low (large baskets) |
| Scoring block (IP, history) | Medium | Variable, false positives |
| Mandatory full prepayment | High | Strong (lost sales) |
Goal: keep false positives below 1 %. Blocking 2 % of fraud while losing 5 % of honest customers is a bad trade.
Mini case study
Ibrahim sells electronics in Abidjan: 400 orders/month, average basket 45,000 FCFA. He accepted screenshots and suffered 3 % fraud, i.e. 12 orders/month at 45,000 FCFA = 540,000 FCFA monthly losses. By enabling automatic PSP status verification before shipping (built-in cost ~25,000 FCFA/month) plus signed delivery proof, he drops fraud to 0.4 %, under 2 orders. Losses fall to ~80,000 FCFA: 460,000 FCFA saved every month.

FAQ
Is a Wave payment screenshot enough as proof?
No, never. Screenshots are faked in seconds. Only a "success" status confirmed on the PSP side (via API or verification code) proves collection and avoids most of the 1-4 % fraud.
How do I limit false positives?
Favor invisible controls (automatic status verification) and reserve manual review for large baskets or risky profiles. Aim for under 1 % of honest customers blocked.
What about "never received" on a delivered parcel?
Keep delivery proof: signature, photo, timestamp, even a handover OTP. This settles most disputes and discourages abusive refunds.
Does automatic verification slow down the order?
No: the PSP call takes a few seconds and stays invisible to the customer. Friction is zero, unlike mandatory full prepayment which drives buyers away.
