The verdict in three sentences
In Dar es Salaam in 2026, M-Pesa (Vodacom) holds around 40 % of the market and Airtel Money trails close behind, both charging 1 to 2 % merchant fees. Setting the wrong operator as default at checkout adds friction that drags down conversion and average basket. The right setup is not to pick one, but to order the display by local market share.
Fees, caps and reach compared
The two operators look alike on caps but diverge on fees and city-level presence. In Dar es Salaam, M-Pesa leads; elsewhere in Tanzania the balance shifts.
| 2026 criterion (Tanzania) | M-Pesa | Airtel Money |
|---|---|---|
| Merchant fee | 1-2 % | 1-2 % |
| Cap per transaction | Per tier | Per tier |
| Dar es Salaam share | ~40 % | ~30 % |
| Settlement | T+1 to T+2 | T+1 to T+2 |
| Confirmation | 30-90 s | 30-90 s |
| Merchant collection | Lipa Namba | Merchant pay |
Why display order shifts the basket
When the customer sees the operator they use first, they pay without hesitation. When they must hunt for it at the bottom of the list, a share abandons. Here is the estimated effect of display order on conversion.
| Checkout setup | Estimated conversion | Average fee | Basket effect |
|---|---|---|---|
| M-Pesa default (Dar) | Baseline | 1.5 % | Optimal |
| Airtel default (Dar) | -3 to -6 pts | 1.5 % | Friction |
| Both, M-Pesa first | +1 to +2 pts | 1.5 % | Best |
| Single operator | -8 to -12 pts | Variable | Lost customers |
Offering both, with the locally dominant operator first, maximises conversion and reach at once.
The francophone parallel: Airtel vs Orange in Niamey
In Niamey, the duel is Airtel Money against Orange Money, with Airtel around 55 % share and merchant fees of 1-1.75 % versus 1.5-2 %. The logic is identical to Dar es Salaam: leading with the city's dominant operator cuts friction, while offering both captures every customer.

Grace sells accessories in Dar es Salaam: 600 orders a month, average basket TZS 60,000, roughly TZS 36,000,000 in revenue. By setting Airtel as default where M-Pesa leads, she loses about 5 points of conversion, or 30 orders, equal to TZS 1,800,000 of revenue gone.
By putting M-Pesa first and keeping Airtel as an option, she recovers those 30 orders while keeping average fees at 1.5 %. The tweak costs almost nothing and pays off immediately.

FAQ
Should I pick a single operator at checkout? No. One operator loses 8 to 12 points of customers. Offer both, with the local leader first to cut friction.
Is M-Pesa always dominant in Tanzania? In Dar es Salaam, yes, around 40 % in 2026. But the balance shifts across cities and rural areas, so an adaptable display matters.
Does the fee difference justify favouring one operator? Barely, since both sit at 1-2 %. The real lever is conversion: leading with the customer's operator earns more than the fractional fee saved.
