The verdict in three sentences
Interoperability lets an Airtel Money customer pay a merchant who only holds M-Pesa, for a cross-network fee of 1 to 3 %. For an online seller the real issue is commercial, not technical: accepting every wallet avoids losing the basket of a customer who isn't on your network. A single multi-wallet checkout can convert 15 to 30 % more baskets (2026 estimate).
Interoperable corridors in East and West Africa (2026)
The figures below are a 2026 order of magnitude (Kenya interop mandate, GhIPSS, Nigeria NIP). Fees and delays vary by bilateral agreement.
| Corridor | Cross-network fee | Delay | Limit per transaction | Coverage |
|---|---|---|---|---|
| M-Pesa to Airtel Money | 1 to 2 % | Instant to 2 min | 150 000 KES | Kenya |
| Airtel Money to M-Pesa | 1.5 to 3 % | Instant to 5 min | 150 000 KES | Kenya |
| GhQR (GhIPSS universal QR) | ~1 % | Seconds | Bank-set | Ghana |
| Nigeria NIP / NQR | Flat/low | Instant | 5 000 000 NGN | Nigeria |
| Cross-network cash-out | 1 to 1.75 % | Immediate | Agent-set | Multi-country |
Note that the delay is usually under 5 minutes, but a failed STK/USSD prompt (timeout) can force a retry. On the merchant side, offering a multi-wallet payment link beats forcing the customer to transfer manually.
The real gain: conversion
A customer landing at checkout with Airtel Money who only sees "M-Pesa" often abandons. Customer-side interoperability exists, but it adds fees and a step. On the merchant side, integrating all wallets removes the problem.
| Checkout scenario | Baskets converted (base 100) | Average fees borne |
|---|---|---|
| M-Pesa only | 70 | 1 % |
| M-Pesa + Airtel | 88 | 1.3 % |
| M-Pesa + Airtel + bank | 96 | 1.5 % |
| Multi-wallet + card | 99 | 1.8 % |
Going from "M-Pesa only" to "multi-wallet" captures 26 baskets out of 100 in our estimate. On a shop doing 300 orders/month that is a direct revenue lever.
Mini case study
Wanjiru, who runs an online grocery in Nairobi, took payments only via M-Pesa. Many Airtel Money customers gave up. Enabling a multi-wallet checkout (M-Pesa + Airtel + card via aggregator) lifted her completed-order rate from 74 % to 95 %. On 400 attempted orders/month at 600 KES average basket, that is about 50 400 KES of extra monthly revenue, for a fee increase of barely 0.5 point.

FAQ
Is interoperability free?
No. A cross-network transfer usually costs 1 to 3 %. That's why, on the merchant side, it's better to accept each wallet directly.
How long does a cross-network transfer take?
Usually under 5 minutes, often instant. A timeout can force a second attempt.
What conversion gain from accepting all wallets?
In our 2026 estimate, going from one to three wallets captures 15 to 30 % more baskets depending on the audience.
What is GhQR for?
It's Ghana's universal QR from GhIPSS linking banks and wallets. For a merchant, the point is that an aggregator exploits it for you, without heavy integration.
Do I need an account with every provider?
No, if you use an aggregator: one integration collects several wallets, at a 1.5 to 3 % commission.
