The verdict in three sentences
In a market where mobile money represents 60 to 80 % of payments, showing the bank card first drives buyers away. The order of options must follow local usage: MoMo on top, a recognized operator visible, the most-used method pre-selected by default. These three adjustments, with no heavy development cost, together are worth +10 to +17 % conversion in 2026.
Three ordering logics compared
You can sort payment methods three ways. Only one serves conversion in a mobile money market.
| Sorting logic | Basis | Conversion effect | Verdict |
|---|---|---|---|
| By local popularity (MoMo first) | Real usage | +6 to +10 % | Recommended |
| By margin (card first) | Seller cost | −5 to −10 % | Avoid |
| Alphabetical default | None | Neutral to negative | Weak |
| Method pre-selected by default | Majority usage | +4 to +7 % | Strong complement |
| Fewer options shown | Simplicity | +3 to +6 % | Useful |
The concrete impact of micro-decisions
Every display detail counts. Here are the estimated gains and losses in 2026.
| Display decision | Estimated effect | Comment |
|---|---|---|
| MoMo shown in position 1 | +6 to +10 % | Follows 60-80 % of usage |
| Recognized operator logo (Orange, MTN, Wave) | +3 to +6 % | Reassures instantly |
| Majority method pre-checked | +4 to +7 % | Removes one click |
| Card imposed / only option | −15 to −25 % drop-off | Excludes the majority |
| Reduce from 6 to 3 options | +3 to +6 % | Less choice paralysis |
| Secondary option folded under "Others" | +2 to +5 % | Keeps the screen clean |

Eric sells auto spare parts in Johannesburg: 1,100 visits/month, conversion 1.6 %, i.e. 18 orders, average basket 35,000 FCFA (approx. €53). His checkout showed the Visa card first and mobile money at the bottom. By moving MTN MoMo and Orange Money to the top, with MoMo pre-selected, he targets +13 %, i.e. 1.81 % and 20 orders. On his high basket, that is 70,000 FCFA of extra revenue per month, for a simple screen reorganization.
FAQ
Should I really put mobile money before the card? Yes, in a market where it carries 60 to 80 % of payments. Placing it on top gains 6 to 10 %, while the card first can lose 5 to 10 %.
Is a default pre-selected method manipulative? No, if you pick the truly majority method: you save a click for the most frequent customer. It adds 4 to 7 % conversion without forcing anyone.
How many payment options should I show? Three to four visible are often enough. Going from 6 to 3 options gains 3 to 6 % by reducing choice paralysis; rare methods go under an "Others" link.
Does the operator logo matter? Yes: a recognized logo (Orange, MTN, Wave) reassures and adds 3 to 6 %. The buyer immediately identifies a method they already use daily.
What about international customers? Keep card and Stripe available, but lower or under "Others." The majority local traffic sees MoMo on top; international traffic finds the card without notable friction.
