The verdict in three sentences
Buy Now Pay Later over mobile money lifts the average basket by 30 to 45 % on goods above GHS 800, but it shifts default risk to whoever carries the credit. An in-house BNPL keeps all the margin but exposes the merchant to 5 to 8 % defaults without scoring. A BNPL partner absorbs the risk for 3 to 6 % commission, which stays profitable when the uplift beats the cost.
In-house or partner: who carries the risk
The choice comes down to a trade-off between kept margin and assumed risk. With in-house BNPL you collect one-third at order via an MTN MoMo direct-debit mandate, then two instalments over 60 days. With a partner, the provider pays you 100 % upfront and handles collection.
| Criterion (2026 order of magnitude) | In-house BNPL | Partner BNPL |
|---|---|---|
| Merchant commission | 0 % | 3 to 6 % |
| Default risk carried | Seller (5 to 8 %) | Partner |
| Cash collected day 0 | 33 % | 100 % |
| Buyer scoring | To build | Included |
| Collection | Your job | Outsourced |
| Setup time | 2 to 4 weeks | 1 to 2 weeks |

Kwame sells appliances in Accra with an average basket of GHS 800 across 300 orders a month. Turning on a partner BNPL at 5 % commission, his basket rises to GHS 1,100 for the 20 % of buyers who adopt splitting. On 60 split orders at GHS 1,100 he collects GHS 66,000, pays GHS 3,300 in commission, but generates roughly GHS 18,000 of extra revenue from the uplift. The partner absorbs defaults. Net positive from month one.
FAQ
Is in-house BNPL really more profitable? Only if your default rate stays under 4 to 5 %. Beyond that, a partner's 3 to 6 % commission is cheaper than your unpaid instalments.
How do instalments get debited automatically? Through a recurring MTN MoMo debit mandate that charges the customer's wallet on the agreed dates across 60 days.
What adoption rate should I expect? Between 15 and 25 % of eligible buyers in 2026, higher on big baskets where splitting eases the customer's cash flow.
Do I need scoring to limit defaults? Yes. Without scoring, defaults reach 5 to 8 %. Scoring based on wallet history and amount cuts that noticeably.
Does splitting work below GHS 800? The basket effect is weak below that threshold; BNPL matters most on electronics, appliances and furniture.
