The verdict in three sentences
In Tanzania, three interoperable operators — M-Pesa, Tigo Pesa and Airtel Money — compete and pull merchant fees down to as low as 0.8%. Unlike a two-player duopoly, this competition means a merchant can shop the cheapest tier without losing customer reach thanks to interoperability. The 2026 decision: pick the operator with the best negotiated rate for your volume, since interoperability lets any customer pay you regardless.
Tanzania fees in 2026
The three dominant operators quote similar bands, with the exact rate set by volume. Here are 2026 orders of magnitude for a verified merchant, in Tanzanian shillings (TZS).
| Criterion | M-Pesa | Tigo Pesa | Airtel Money |
|---|---|---|---|
| Merchant fee | 0.8% to 2% | 0.8% to 2% | 0.8% to 2% |
| Per-transaction limit | 5,000,000 TZS | 5,000,000 TZS | 5,000,000 TZS |
| Settlement | T+1 | T+1 | T+1 |
| Interoperability | Yes | Yes | Yes |
| Refund | Free | Free | Free |
Interoperability is the differentiator: a customer on any network can pay a merchant on any other, so price competition does not cost reach.
Cameroon fees in 2026 (regional reference)
For contrast, Cameroon's duopoly keeps rates higher. Amounts are in West African CFA francs (FCFA).
| Criterion | MTN MoMo | Orange Money |
|---|---|---|
| Merchant fee | 1.5% | 1.7% |
| Minimum fixed fee | 100 FCFA | 100 FCFA |
| Per-transaction limit | 1,000,000 FCFA | 1,000,000 FCFA |
| Settlement | T+1 | T+2 |
Where Tanzania's three-player competition drives rates to 0.8%, Cameroon's two-player market holds them at 1.5-1.7% — a textbook case of competition lowering cost.
Fee by basket tier in Tanzania
| Basket | Cost at 0.8% | Cost at 1.5% | Difference |
|---|---|---|---|
| 5,000 TZS | 40 TZS | 75 TZS | 35 TZS |
| 20,000 TZS | 160 TZS | 300 TZS | 140 TZS |
| 50,000 TZS | 400 TZS | 750 TZS | 350 TZS |
| 200,000 TZS | 1,600 TZS | 3,000 TZS | 1,400 TZS |
| 1,000,000 TZS | 8,000 TZS | 15,000 TZS | 7,000 TZS |
The cheaper 0.8% tier nearly halves cost versus 1.5%, and the gap scales directly with basket size.

Paul, who runs a hardware store in Dar es Salaam, processes TZS 12,000,000 per month split evenly across the three operators. At a blended 1.5%, his fees reach TZS 180,000. By concentrating 80% of volume on the operator offering a negotiated 0.9% tier, his blended cost drops to about TZS 130,000, saving roughly TZS 50,000 per month and TZS 600,000 a year.
FAQ
Why is Tanzania cheaper than Cameroon?
Because three interoperable operators compete, pushing merchant fees to 0.8%. Cameroon's two-player duopoly faces no such pressure and holds rates at 1.5-1.7%.
Does interoperability let me use just one operator?
Yes. In Tanzania a customer on any network can pay a merchant on another, so you can choose the cheapest operator without losing reach — unlike fragmented markets.
What is the 2026 per-transaction limit?
All three operators cap around 5,000,000 TZS per transaction for a verified merchant — much higher than Cameroon's 1,000,000 FCFA cap.
How fast is settlement?
All three settle at T+1 (next business day). For tight cash flow, this uniformity means the choice comes down to price and reliability, not speed.
Should I negotiate a rate?
Yes, above meaningful monthly volume operators grant lower tiers toward 0.8-0.9%. Concentrating volume on one operator helps you cross the negotiation threshold faster.
