The verdict in three sentences
Cash on delivery (COD) reassures the buyer but explodes your hidden costs: refusals, re-deliveries and locked cash-flow. Prepaid mobile money converts a little less (5 to 15 points lower) but its return rate drops to 3-8 % versus 15-30 % for COD. Across 100 orders, the net cash collected almost always favors mobile money.
Why COD inflates the return rate
When a buyer pays nothing at order time, they carry no commitment cost. They order on impulse, forget, change their mind, or simply refuse the parcel at the door. Prepayment creates a financial commitment: someone who already paid shows up to collect the parcel.
| Metric (2026 order of magnitude) | Cash on delivery | Prepaid mobile money |
|---|---|---|
| Return / refusal rate | 15-30 % | 3-8 % |
| Cost of a failed delivery | 1,500-3,000 FCFA | ~0 FCFA |
| Cash locked up | 3-10 days | 0-2 days |
| Cash-handling fees | 1-3 % | 1-1.8 % (MoMo fees) |
| Checkout conversion rate | Baseline | -5 to -15 points |
| Fake-order risk | High | Low |
COD wins on raw conversion but loses on almost everything else. The real question is not "how many orders?" but "how much net cash collected?".
Unit economics: 100 orders compared
Take an average basket of 20,000 FCFA and a 40 % gross margin (8,000 FCFA per delivered order).
| Line item (base 100 orders) | Cash on delivery | Prepaid mobile money |
|---|---|---|
| Orders placed | 100 | 88 (conversion -12 pts) |
| Return / refusal rate | 22 % | 6 % |
| Orders actually delivered | 78 | 83 |
| Delivered gross margin | 624,000 FCFA | 664,000 FCFA |
| Cost of failed deliveries | 22 × 2,200 = 48,400 FCFA | 5 × 0 = ~0 FCFA |
| Payment fees | ~14,000 FCFA | ~11,600 FCFA |
| Estimated net margin | ~561,600 FCFA | ~652,400 FCFA |
Even with 12 fewer conversion points, mobile money produces ~90,000 FCFA more net margin per 100 orders, purely by killing returns and re-deliveries.

Mini case study
Fatou runs a cosmetics shop in Dakar, 300 orders/month, average basket 20,000 FCFA. On 100 % COD she suffered 24 % refusals, i.e. 72 failed drops/month at 2,200 FCFA = 158,400 FCFA/month in logistics losses, plus 6 days of locked cash. By moving 60 % of orders to Wave prepayment (3 % discount), her overall refusal rate fell to 11 %. Result: under 100,000 FCFA in logistics losses and cash available almost immediately. Estimated net gain: over 80,000 FCFA/month.
FAQ
Doesn't mobile money scare off distrustful buyers? Partly yes, hence the 5-15 conversion points lost. But those buyers are often the ones most likely to refuse under COD: you mostly lose orders that would have been returned anyway.
Should I remove COD entirely? Rarely. The winning 2026 model is hybrid: COD available but prepayment rewarded (free delivery or a 3-5 % discount) to shift 30-50 % of volume.
What does a failed delivery really cost? Between 1,500 and 3,000 FCFA depending on the city: fuel, courier time, re-scheduling, and sometimes the parcel's return to the warehouse. Across hundreds of orders, it is your top leakage line.
Does prepayment really speed up my cash-flow? Yes. Under COD, the courier or aggregator remits cash in 3 to 10 days. With mobile money, money lands within 0 to 48 h, cutting your working-capital need.
What return rate should I target in 2026? Below 10 % across all payment modes. Above 15 %, your problem is not the product but the payment mode and address quality.
