The verdict in three sentences
Cash on delivery (COD) reassures the buyer but costs the seller dearly: 20 to 40 % returns, tied-up cash flow and lost logistics fees. Prepaid mobile money costs around 1 % in fees but secures collection, eliminates fake buyers and frees up cash immediately. The right 2026 trade-off: incentivize prepaid with a small discount (3-5 %) that stays well below the real cost of COD returns.
The true cost of cash on delivery
COD looks free to the seller, but every return destroys margin: round-trip delivery, sometimes damaged product, wasted time, cash blocked during the delivery cycle. Here's the comparison on a typical 20,000 FCFA order.
| Item | Cash on delivery (COD) | Prepaid mobile money |
|---|---|---|
| Transaction fee | 0 % | ~1.0-1.5 % (300 FCFA) |
| Return / refusal rate | 20-40 % | 3-6 % |
| Cash collected | D+3 to D+10 | Immediate |
| Average cost of a return | 2,000-4,000 FCFA | negligible |
| Fake buyer risk | High | Near zero |
| Courier cash-collection fee | 300-600 FCFA | 0 |
On 100 COD orders at 30 % returns, you deliver 130 times to sell 100: the logistics overhead alone eats a large share of margin. These figures are 2026 estimates for Dakar and Abidjan.
The switch threshold to prepaid
The question isn't COD or prepaid, but how much discount to offer to convert a COD buyer into a prepaid buyer without destroying margin. Here's the modeling.
| COD return rate | Real cost of a return | Profitable prepaid discount |
|---|---|---|
| 15 % | ~450 FCFA / order | up to 2 % |
| 25 % | ~750 FCFA / order | up to 4 % |
| 35 % | ~1,100 FCFA / order | up to 5-6 % |
| 40 % | ~1,300 FCFA / order | up to 6-7 % |
In other words, if your COD return rate hits 35 %, offering 5 % off for advance Wave/Orange Money payment costs you less than absorbing the returns. In Lagos and Nairobi, COD fraud and fake numbers push even harder toward prepaid via Paystack and M-Pesa, where COD declines year after year.

Fatou sells children's clothes in Thiès, 300 orders/month at 20,000 FCFA, in COD with 32 % returns. She therefore delivers 396 times to sell 204. Each return costs her ~1,000 FCFA: 96 returns × 1,000 = 96,000 FCFA/month of pure loss, plus blocked cash flow. She switches to prepaid mobile money with a 4 % incentive discount. Returns drop to 6 %. On 300 prepaid orders at 19,200 FCFA net (after discount), she collects 5,760,000 FCFA immediately, versus an irregular, reduced COD flow. Estimated net gain: +700,000 FCFA/month in recovered margin and cash flow.
FAQ
Should you remove cash on delivery entirely?
No, not all at once: it still reassures some customers. Keep it as a secondary option, but feature prepaid prominently with an incentive discount to gradually shift volume.
What return rate justifies pushing prepaid?
From 20 % COD returns, prepaid with a 3-4 % discount becomes more profitable. Above 30 %, it's an economic no-brainer.
Does prepaid scare off wary customers?
Less than you'd think if you show reviews, a WhatsApp number and a clear refund policy. Trust is built with social proof, not COD.
How to incentivize prepaid without breaking margin?
Offer a discount calibrated to your real return rate (see table), or free shipping on prepaid. The cost stays below that of COD returns.
