The verdict in three sentences
Cash on delivery reassures the buyer but bleeds the merchant: between 15 and 30 % of parcels come back refused, and each round trip costs 2,000 to 4,000 FCFA. The most effective fix in 2026 is not to drop COD but to secure it: a 20 % mobile money deposit commits the customer and cuts the refusal rate threefold. Phone OTP verification and blocking repeat offenders round out the setup to protect the margin.
Pure COD vs COD with deposit
Pure COD leaves the entire risk on the merchant. COD with a deposit shifts part of the commitment to the customer, without removing the comfort of paying the rest on delivery.
| Criterion | Pure COD | COD with 20 % deposit |
|---|---|---|
| Refusal rate 2026 | 15-30 % | 5-10 % |
| Customer commitment | None | Financial (deposit) |
| Lost round-trip cost | 2,000-4,000 FCFA | Covered by deposit |
| Cash before delivery | 0 | 20 % collected |
| Checkout friction | Low | Moderate |
| Fake-number fraud | High | Low (OTP + deposit) |
Anti-fraud levers and their impact
Several levers stack. Here are the 2026 measures and their estimated effect on refusal rate and margin.
| Lever | Effect on refusals | Setup cost |
|---|---|---|
| 20 % mobile money deposit | Refusals cut threefold | Payment module |
| Phone OTP verification | Fake numbers eliminated | SMS ~15 FCFA/send |
| WhatsApp confirmation D-1 | -20 to -30 % refusals | Near zero |
| Blocking repeat offenders | Repeat fraud stopped | Customer base |
| Geolocated address | Failed deliveries reduced | Form field |
| Per-customer COD cap | Exposure limited | Business rule |
Mini case study
Modou delivers shoes in Dakar and Rufisque, 300 COD orders/month at 18,000 FCFA. His refusal rate is 25 % (75 parcels), each costing 3,000 FCFA in lost round trips, i.e. 225,000 FCFA/month in pure losses. He introduces a 20 % mobile money deposit (3,600 FCFA) and a WhatsApp confirmation the day before. His refusal rate drops to 8 % (24 parcels), and the deposit covers the fees. Estimated saving: over 180,000 FCFA/month of recovered margin.

What is the normal COD refusal rate in Senegal in 2026?
Between 15 and 30 % depending on city, product and basket. Above 30 %, your COD is no longer profitable and you should move part of your orders to prepaid or deposit.
How does a 20 % deposit reduce fraud?
It creates financial commitment: a customer who has already paid 20 % comes to collect the parcel. In practice this cuts the refusal rate threefold, and the deposit covers the logistics cost of any return.
Is OTP verification essential?
Yes, to eliminate fake numbers, the main source of ghost parcels. An OTP SMS costs about 15 FCFA: negligible against a failed round trip at 3,000 FCFA.
What about repeat-refusal customers?
Block them or move them to mandatory prepayment. A small minority of customers generates most refusals; spotting them via your database durably protects your margin.
Does WhatsApp confirmation really change anything?
Yes: a simple message the day before delivery, asking to confirm presence and address, cuts refusals by 20 to 30 % at near-zero cost. It is the best-ROI lever.
