The verdict in three sentences
In Tanzania, an online store that doesn't accept M-Pesa and the main mobile money wallets cuts itself off from over 90 % of the market. Cards are marginal (under 5 %), useful mainly for the diaspora, while cash on delivery eats margin with 15-25 % failures. The right 2026 mix is M-Pesa + Mixx/Airtel Money on prepayment, with COD reserved for loyal customers or large baskets with a deposit.
Market share, fees and risk by method
Mobile money heavily dominates Tanzanian online payments. The choice isn't about fees (comparable) but about operator coverage and loss risk.
| Method | Estimated 2026 share | Merchant fee | Loss risk | Recommendation |
|---|---|---|---|---|
| M-Pesa | ~85 % | 1-2 % | Low | Essential |
| Mixx / Airtel Money | ~10 % | 1-2 % | Low | Recommended |
| Visa/Mastercard | < 5 % | 2.5-3.5 % | 3DS, fraud | Diaspora |
| Cash on delivery | Variable | Logistics | 15-25 % fail | Caution |
Offering M-Pesa plus a second wallet covers nearly all buyers. Adding cards for the diaspora helps but is secondary. The real trade-off is COD.
The cash-on-delivery trap
COD reassures the customer but costs the merchant. With 15-25 % of orders refused or returned, each undelivered parcel means 1,500-4,000 FCFA equivalent of lost logistics, plus tied-up stock. On a 30 % margin, these returns can shave 4-8 points off profitability.
| Scenario, 100 orders | All M-Pesa prepaid | All COD |
|---|---|---|
| Orders delivered | 98 | 78 |
| Return logistics cost | ~15,000 FCFA | ~66,000 FCFA |
| Cash collected | Immediate | Delayed 3-7 d |
| Payment fee | ~1.5 % | 0 % but losses |
| Net margin preserved | High | -4 to -8 pts |
The recommended combination
For a Tanzanian store in 2026: M-Pesa + a second wallet first, cards for international buyers, and COD only with a 20-30 % mobile money deposit to filter non-serious orders. This structure preserves cash flow and limits returns.
Mini case study
Joseph sells electronics in Dar es Salaam: 120 orders/month, average basket 45,000 FCFA equivalent, 22 % margin (9,900 FCFA). On full COD he faces 20 % returns (24 orders), losing 24 × 3,000 FCFA logistics = 72,000 FCFA, plus 24 lost sales (237,600 FCFA of vanished margin). Switching to M-Pesa prepaid with a mandatory deposit on COD, returns fall to 5 %. He recovers about 18 sales/month — +178,200 FCFA in monthly margin — and cash collected immediately instead of 3-7 days later.

FAQ
Must I offer M-Pesa and a second wallet?
Yes. Together they cover over 90 % of online payments in Tanzania. Offering only one wallet excludes a large share of your buyers.
Are cards useful in Tanzania?
They represent under 5 % of online payments, mostly the diaspora and some premium customers. Useful as a complement, never as the main method.
Is cash on delivery profitable?
Rarely as-is: 15-25 % failures and 1,500-4,000 FCFA logistics per return. A 20-30 % mobile money deposit makes it viable.
What are merchant mobile money fees?
Generally 1-2 % depending on operator and volume. Far below the losses from unsecured COD returns.
How much does payment integration cost?
Depending on the platform, M-Pesa + wallet integration is included in a custom store from 600,000 FCFA equivalent, webhook testing included.
