The verdict in three sentences
Cash-on-delivery (COD) still accounts for nearly 70 % of e-commerce orders in Nairobi in 2026, but its 22 % failure rate eats into margin. An OTP confirmation before dispatch cuts failures by roughly 40 %, and a 20 % mobile-money deposit filters out non-serious orders. COD isn't the problem: the lack of verification before you send the rider out is.
Why COD fails (and what it costs)
Every refused or undelivered parcel costs the round-trip transport, tied-up stock and the rider's time. On average, a failed delivery costs 2,500 to 4,000 FCFA in fuel, time and restocking (2026 order of magnitude).
| Failure cause | Share of failures | Countermeasure | Estimated reduction |
|---|---|---|---|
| Customer absent | 34 % | Slot confirmed the day before | -45 % |
| Fake / unreachable number | 21 % | OTP confirmation by SMS/WhatsApp | -70 % |
| Refusal at the door | 18 % | 20 % mobile-money deposit | -50 % |
| Address not found | 15 % | Address scoring + GPS pin | -55 % |
| Price disputed | 7 % | Written recap before dispatch | -60 % |
| Change of mind | 5 % | Benefit reminder + product photo | -30 % |
The three levers that work
OTP confirmation, deposit and address scoring stack together. Here is their 2026 effect over 100 COD orders, average basket 18,000 FCFA.
| Lever | Unit cost | Failures before | Failures after | Net gain /100 orders |
|---|---|---|---|---|
| Pre-dispatch OTP confirmation | 25 FCFA | 22 | 13 | ~27,000 FCFA |
| 20 % mobile-money deposit | 0 (customer fees) | 22 | 11 | ~33,000 FCFA |
| Address scoring | 0 (internal rule) | 22 | 16 | ~18,000 FCFA |
| All three combined | ~25 FCFA | 22 | 8 | ~42,000 FCFA |
The 20 % deposit is the most powerful filter: a customer who has paid 3,600 FCFA on an 18,000 basket shows up or waits for the rider.
Mini case study
Estelle, who runs a cosmetics shop in Nairobi, handles 300 COD orders a month, average basket 18,000 FCFA. Her failure rate is 22 %, meaning 66 failed parcels and about 231,000 FCFA in lost logistics costs every month.
She switches on OTP confirmation (25 FCFA × 300 = 7,500 FCFA/month) and a 20 % mobile-money deposit. Her failure rate drops to 9 %, or 27 parcels. She saves ~136,000 FCFA/month in logistics costs and recovers the margin on 39 extra sales actually delivered. Payback within the first week.

FAQ
Does a deposit scare customers away?
In 2026, about 8 % of customers drop off when asked for a deposit, but you mainly eliminate non-serious orders. Revenue actually delivered rises 10 to 15 % despite the filter.
How much does an OTP confirmation cost?
An OTP SMS costs 20 to 30 FCFA, a WhatsApp Business message around 25 FCFA. On an 18,000 FCFA basket, that's under 0.2 % of the basket to avoid a 3,000 FCFA failure.
Is address scoring complicated?
No: a simple rule (known neighborhood, shared GPS, customer history) is enough. It cuts address failures by ~55 % with no complex software.
Should I drop COD for mobile money?
Not yet: COD is still the majority. The 2026 goal is hybrid COD (mobile-money deposit + balance on delivery) combining customer trust and seller security.
What failure rate should I target in 2026?
A well-equipped store gets below 10 % failures. Under 8 %, COD logistics become profitable and predictable.
