The verdict in three sentences
Cash on delivery (COD) reassures the wary buyer but triggers 20% to 35% of doorstep refusals or returns, which destroy margin and tie up cash flow. Prepaid mobile money (M-Pesa, Airtel Money, wallets) drops the return rate to 3% to 8% but converts slightly less at entry. The smart 2026 strategy is not to pick one, but to force prepaid where COD bleeds the most.
COD versus prepaid: the real hidden cost
COD shows a better apparent conversion, but every doorstep refusal costs a logistics round trip and locks up stock. Prepaid shifts that cost: slightly lower conversion, but near-zero returns and cash collected immediately.
| Criterion | Cash on delivery | Prepaid mobile money |
|---|---|---|
| Refusal/return rate | 20-35% | 3-8% |
| Cost of an unpaid round trip | 1,500-4,000 FCFA | ~0 |
| Cash collected | On delivery | Immediate |
| Address fraud risk | High | Low |
| Conversion at entry | Higher | -5 to -10 pts |
| Stock tied up | Heavy | Light |
The middle-ground options
Between all-COD and all-prepaid, several formulas cut risk without killing conversion.
| Formula | Expected return | When to use |
|---|---|---|
| Full COD | 20-35% | Loyal customer, safe zone |
| Half-prepaid (30-50% deposit) | 8-12% | New customer, mid basket |
| Prepaid with 3-5% discount | 3-8% | To drive the switch |
| Mandatory prepaid | 3-5% | High-refusal zone, high basket |
Key lever: offer a 3 to 5% discount for advance payment. The revenue given up on the discount is far below the cost of the round trips avoided. Force prepaid above a certain basket (say 50,000 FCFA) and in zones where your history shows a refusal rate above 25%.
Mini case study
Wanjiru sells clothing online in Nairobi, 300 orders a month on COD, average basket 6,000 FCFA equivalent, 30% refusal rate. Each refusal costs 3,000 FCFA in round trip: 90 refusals x 3,000 = 270,000 FCFA in monthly logistics losses, before lost margin. She moves new customers and baskets over 50,000 FCFA to prepaid with a 4% discount. The overall refusal rate falls to 10%, meaning 30 refusals: logistics losses drop to 90,000 FCFA. Net saving: about 180,000 FCFA per month, discount included.

What return rate should I expect on COD versus prepaid?
COD typically generates 20 to 35% refusals or returns, versus 3 to 8% on prepaid. The gap comes from the lack of financial commitment at order time.
How much does an unpaid round trip cost?
Between 1,500 and 4,000 FCFA depending on distance and carrier in 2026. On 90 refusals a month, the logistics bill quickly tops 200,000 FCFA.
Is the prepayment discount worth it?
Yes: a 3 to 5% discount costs far less than the round trips avoided. It also shifts cash flow to immediate collection.
Should I drop COD entirely?
Not necessarily: keep it for loyal customers in safe zones. Force prepaid for new customers, large baskets and high-refusal zones.
What basket threshold triggers mandatory prepaid?
A threshold around 50,000 FCFA works well: above that, the cost of a refusal gets too heavy. Adjust to your margin and per-zone history.
