The verdict in three sentences
On carts above 100,000 FCFA, offering a 3-installment payment lifts conversion by 20 to 35 % in 2026. The risk is manageable: the default rate sits between 4 and 7 %, operator fees per installment around 1.4 %, and a 34 % down payment covers most of the risk while staying affordable. Well calibrated, installments improve both revenue and perceived cash flow.
Full prepayment vs three installments
Installments remove the main psychological barrier on large carts: paying a big sum at once. But you must measure the real cost.
| Criterion | Full prepayment | 3x free for customer |
|---|---|---|
| Conversion cart > 100,000 FCFA | baseline | +20 to 35 % |
| Immediate collection | 100 % | 34 % (down payment) |
| Cumulative operator fees | ~ 1.4 % | ~ 4.2 % (3 installments) |
| Default risk | 0 % | 4 to 7 % |
| Tracking complexity | low | medium |
| Cash-flow effect | strong immediate | spread over 60 days |
The extra fees (about 2.8 additional points) and the default risk must be weighed against the additional revenue generated. On a high average cart, the conversion gain largely dominates.
Profitability by product category
| Category | Average cart | 3x conversion gain | Estimated default | Verdict |
|---|---|---|---|---|
| Appliances | 250,000 FCFA | +32 % | 6 % | Very profitable |
| Furniture | 180,000 FCFA | +28 % | 5 % | Profitable |
| Smartphones | 200,000 FCFA | +30 % | 7 % | Profitable |
| Premium fashion | 120,000 FCFA | +22 % | 4 % | Profitable |
| Grocery | 25,000 FCFA | +4 % | 3 % | Little use |
| Cosmetics | 40,000 FCFA | +8 % | 4 % | Marginal |
Installments mainly make sense above 100,000 FCFA. Below that, the conversion gain does not offset fees and complexity: reserve 3x for high-ticket categories.

Mini case study
Moussa sells appliances in Dakar, 250,000 FCFA average cart, 120 sales per month. On full payment, his conversion plateaus. Enabling 3x (34 % down, two installments at 30 days), conversion rises 30 %, i.e. 156 sales. Revenue: 39,000,000 FCFA/month versus 30,000,000 before. Even absorbing 6 % default (about 2,340,000 FCFA of risk) and 2.8 fee points, his net gain exceeds 6,000,000 FCFA/month.
FAQ
What down payment to require? The optimal 2026 order of magnitude is around 34 %. High enough to cover margin and filter out non-serious buyers, low enough not to deter the purchase.
How to limit the default rate? Tie installments to the mobile money number, send a WhatsApp reminder 48 h before each due date, and hold delivery of large items until the first confirmed charge. This keeps default under 7 %.
Is 3x suited to grocery? Rarely. On 25,000 FCFA carts the conversion gain is around 4 %, insufficient against cumulative fees and tracking complexity.
Who pays the fees on extra installments? In 2026 the winning practice is "3x free" for the customer, with the merchant absorbing about 2.8 additional fee points. This cost is largely offset by the sales volume gained.
Do you need a credit score? Not in the banking sense. A simple internal history (customer already delivered and paid) is enough to open higher limits and cut risk on reliable repeat buyers.
