The verdict in three sentences
Cash on delivery (COD) reassures the African buyer and can add +18 points of conversion, but it bleeds margin through 15 % door refusals, cash handling and cash locked up for 7-14 days. Prepaid mobile money (Wave, Orange Money) is cheaper with only 2 % refusals, but it scares new customers. The winning setup in 2026: prepayment by default, COD reserved for loyal customers or verified baskets.
COD vs prepaid: the duel across 6 metrics
The two methods do not differ only on price: they split on conversion, returns, cash flow and fraud. Here is the 2026 data comparison.
| Metric | Cash on delivery | Prepaid mobile money |
|---|---|---|
| Effect on conversion | +18 pts (reassures) | Baseline |
| Refusal rate at delivery | 15 % | 2 % |
| Processing cost / order | 500 FCFA (cash) | 50-100 FCFA (MM fees) |
| Cash locked up | 7 - 14 days | 0 - 2 days |
| Fraud / non-payment risk | High | Low |
| Returns after order | 12-15 % | 3-4 % |
COD wins the initial conversion battle but loses the profitability war: every door refusal is a run paid for nothing plus a product that sometimes comes back damaged.
The real impact on margin
A 15 % refusal rate does not only cost the product: it adds the outbound run, the return run, cash handling and the tied-up capital. Here is the cost structure per 20,000 FCFA order.
| Item | COD | Prepaid |
|---|---|---|
| Payment fees | 500 FCFA | 80 FCFA |
| Cost of refusals (averaged) | 900 FCFA | 120 FCFA |
| Cash-flow financing cost | 150 FCFA | 20 FCFA |
| Total overhead / order | 1,550 FCFA | 220 FCFA |
| Net margin kept (on 5,000 FCFA margin) | 3,450 FCFA | 4,780 FCFA |
At equal gross margin, prepayment keeps about 1,330 FCFA more per order. On 600 orders/month, that is nearly 800,000 FCFA in extra margin.
Mini case study
Ibrahima, an online shoe seller in Thiès, handles 500 orders/month at 20,000 FCFA, all COD with 15 % refusals. His refusals cost him 75 failed orders × 1,550 FCFA overhead = about 116,000 FCFA/month in losses, plus 1.5 million FCFA of cash permanently locked. Moving to 70 % prepaid mobile money / 30 % COD with a small incentive (free delivery if prepaid), his overall refusal rate falls to 6 %, his losses to 45,000 FCFA/month, and he frees nearly 1 million FCFA of cash to restock.

FAQ
Does COD really increase sales?
Yes, it adds up to +18 points of conversion among buyers who do not yet trust a store. But part of those orders turns into door refusals (15 %), which cancels the gain.
How much does cash handling cost?
About 500 FCFA per order across courier time, loss risk and accounting reconciliation, versus 50-100 FCFA in fees for a Wave or Orange Money payment.
How do you push prepayment without losing customers?
Offer a concrete perk: free delivery or 5 % off if prepaid. This 500-1,000 FCFA incentive costs less than the average COD overhead (1,550 FCFA).
Does prepayment scare off new customers?
Only 2 % refuse at the moment of paying, but initial conversion is lower. Hence the value of a mix: COD allowed on the first order, prepayment encouraged afterwards.
How much cash does COD lock up?
Between 7 and 14 days of revenue in transit. For 500 orders/month at 20,000 FCFA, that can be 1.5 to 2 million FCFA permanently frozen.
