The verdict in three sentences
Cash on delivery (COD) reassures the customer but costs dearly in returns, tied-up cash and rider risk. Prepaid mobile money collapses returns but slows conversion when trust is not yet established. The most profitable 2026 model in Nairobi is hybrid: a 30% deposit via M-Pesa, the balance on delivery, which halves returns while preserving conversion.
Full COD vs prepaid: the hidden costs
COD looks free, but every order refused at the door has already cost picking, packing and a round trip. Prepaid removes that risk but demands a trust not every customer has yet. Here are the 2026 order-of-magnitude figures (KES-driven behavior, FCFA equivalents for regional comparison).
| Criterion | Full COD | Prepaid mobile money | Hybrid (30% deposit) |
|---|---|---|---|
| Refusal / return rate | 15 - 30% | < 5% | 7 - 12% |
| Tied-up cash | High (rider) | None | Reduced |
| Rider risk | High | None | Low |
| Checkout conversion | Baseline (100%) | -10 to -20% | -3 to -7% |
| Cost per return | 2,000 - 5,000 FCFA | ~0 | 2,000 - 5,000 FCFA (rare) |
| Mobile money fee | 0 | 1 - 1.5% | 1 - 1.5% on deposit |
COD shows the best apparent conversion, but its 15-30% return rate erases the advantage: one order in four comes back, each costing 2,000 to 5,000 FCFA of lost logistics.
Quantifying the impact over 100 orders
Compare 100 orders at 15,000 FCFA cart, 25% margin (3,750 FCFA/order), average logistics cost 2,800 FCFA per return.
| Model | Delivered paid orders | Returns | Gross margin | Return cost | Net margin |
|---|---|---|---|---|---|
| Full COD | 78 (22% return) | 22 | 292,500 FCFA | 61,600 FCFA | 230,900 FCFA |
| Prepaid (but -15% conversion) | 85 paid (of 85 placed) | 4 | 318,750 FCFA | 11,200 FCFA | 307,550 FCFA |
| Hybrid 30% deposit | 91 | 9 | 341,250 FCFA | 25,200 FCFA | 316,050 FCFA |
The hybrid model combines near-intact conversion with a controlled return rate, making it the most profitable in net margin. The deposit commits the customer psychologically without demanding full upfront payment.

Mini case study
Brian sells phone accessories online in Nairobi, 100 orders/month on COD, average cart 15,000 FCFA. He suffers 24% returns, i.e. 24 parcels coming back each month at 2,800 FCFA of lost logistics each: 67,200 FCFA gone monthly, plus cash stuck with his riders.
He switches to hybrid: a 4,500 FCFA (30%) M-Pesa deposit at order, 10,500 FCFA balance on delivery. Curious and fake buyers drop off before paying the deposit. Result: returns fall to 9%, i.e. 9 parcels, for 25,200 FCFA of logistics. He saves 42,000 FCFA/month and recovers cash faster, deposits landing instantly in his mobile money account.
FAQ
Should COD be avoided entirely? No, it still helps convert wary new customers. But its 15-30% return rate means pairing it with a deposit as soon as volume grows.
Does a deposit scare customers away? Marginally: a 30% deposit lowers conversion by 3 to 7%, well below the 10-20% of full prepaid, and offset by the drop in returns.
What mobile money fees in Nairobi? Expect an order of magnitude of 1 to 1.5% on M-Pesa collection. On a 4,500 FCFA deposit that is about 45 to 70 FCFA, negligible against the cost of a return.
How do you secure the COD balance? The rider collects the balance by mobile money rather than cash where possible, removing cash risk and speeding up reconciliation.
Can all this be automated at checkout? Yes: your store triggers the mobile money deposit, marks the order "deposit paid" and passes the balance to collect to the rider. That is the unified payment module we integrate.
