The verdict in three sentences
Three-installment payment via mobile money turns a too-high price into three acceptable payments, lifting conversion by +34% on baskets above 150,000 FCFA. Risk is controlled with a deposit at order, light scoring and a held warranty until the final debit. A homegrown implementation via recurring mobile money debit costs less than waiting for a mature local BNPL.
What installments really change
Installment payment works on two levers: it raises the conversion rate of large baskets and it raises the average basket, because the customer dares to buy more.
| Metric | Without 3x | With 3x |
|---|---|---|
| Conversion basket >150,000 FCFA | 0.9% | 1.2% (+34%) |
| Average basket | Base 100 | +40% |
| Default rate | — | 6 - 12% |
| Deposit required | — | 30 - 40% |
| Number of debits | 1 | 3 (D0, D+30, D+60) |
| Margin protected by held warranty | — | Until 3rd debit |
A 6-12% default is absorbable as long as the deposit covers the cost of goods and final delivery only happens after one or two secured debits.
Mechanics, scoring and regional comparison
A homegrown implementation via recurring debit follows a simple, robust mechanic.
| Step | 2026 setting | Goal |
|---|---|---|
| Deposit at order | 30 - 40% of basket | Cover product cost |
| Debit 2 (D+30) | Scheduled mobile debit | Secure the 2nd tranche |
| Debit 3 (D+60) | Scheduled mobile debit | Settle the sale |
| Light scoring | History + amount + KYC | Filter high risks |
| Held warranty | Goods delivered after tranche 2 | Limit loss on default |
| Automatic reminder | SMS + WhatsApp at D-2 | Cut unpaid |
Compared with the nascent BNPLs of Ghana and Nigeria, still costly and thin in coverage in the CFA zone, a homegrown setup via recurring mobile money debit remains the fastest to deploy and the cheapest in fees for a local e-merchant.
Mini case study
Awa sells home appliances online. Average basket 180,000 FCFA, 50 orders/month, but a high abandonment rate on heavy baskets.
Her math: enabling 3x with a 35% deposit, her conversion on baskets >150,000 FCFA rises +34%, bringing 12 extra orders per month. With the average basket boosted +40%, it moves from 180,000 to 210,000 FCFA. Added revenue: 12 × 210,000 = 2,520,000 FCFA/month. With a 10% default rate, she loses about 1.2 orders, but the 35% deposit (73,500 FCFA) already covers most of the product cost. Net loss controlled, net gain firmly positive.

FAQ
Does 3-installment payment really boost sales?
Yes: on baskets above 150,000 FCFA, it raises conversion by about +34% and the average basket by +40%, because it makes a high price psychologically accessible.
How do I manage default risk?
With a 30-40% deposit covering product cost, light scoring (history, amount, KYC) and a warranty held until the final debit. The 6-12% default rate becomes absorbable.
Should I wait for a mature local BNPL?
No: the nascent BNPLs of Ghana and Nigeria remain costly and thin in CFA-zone coverage. A homegrown setup via recurring mobile money debit deploys faster and costs less in fees.
When should I deliver the goods?
After the deposit clears, and ideally after the second debit for the heaviest baskets. The held warranty limits loss to about 10% of the basket on total default.
How much does adding installments cost?
It fits into a Growth e-commerce base (toward 2,000,000 FCFA) with mobile money and scheduled recurring debit. ROI shows from the first large baskets converted.
