The verdict in three sentences
Showing a single payment button means losing buyers on rival networks: about 24% of customers are on an operator other than your default. A multi-operator selector that auto-detects the network from the phone prefix (96% accuracy) and covers Wave, OM, MTN, Moov, Airtel and M-Pesa lifts conversion by +11%. One API abstraction, a USSD fallback, and the integration fits in 2 days.
Single button or smart selector: what's the conversion impact?
A single button forces the buyer toward a wallet they may not have. The smart selector recognizes their network and offers the right rail by default.
| Approach | Network coverage | Conversion | Effort |
|---|---|---|---|
| Single-operator button | 1 network | Baseline | Minimal |
| Manual operator list | 3 to 6 | +5 to 7 pts | Low |
| Selector + prefix auto-detect | 6 networks | +11 pts | 2 days |
| Selector + USSD fallback | 6 + feature phones | +11 pts, fewer failures | 2 days |
| Generic PSP redirect | Varies | +3 to 6 pts | Low |
Auto-detection removes a decision from the customer: they type their number, the right logo lights up. Logo trust cues reassure and cut hesitation.
Which operators to cover and how to detect the network?
The phone prefix reveals the operator in the vast majority of cases; the selector pre-picks the right wallet and lets the user switch manually.
| Operator | Main zone | Prefix detection | Fallback |
|---|---|---|---|
| Wave | Senegal, CI | Yes (entered number) | USSD/QR |
| Orange Money | Francophone zone | Yes | USSD |
| MTN MoMo | Ghana, CI, Nigeria... | Yes | USSD |
| Moov Money | CI, Benin, Togo... | Yes | USSD |
| Airtel Money | East/Central Africa | Yes | USSD |
| M-Pesa | Kenya, Tanzania... | Yes | STK push |
Key figures: 24% of buyers off the default network, 96% auto-detect accuracy, 6 operators covered by one API abstraction. The USSD fallback catches feature phones and cases where the wallet app is not installed.
Mini case study
Moussa sells online in Abidjan with a single Wave button. On 1,000 payment-ready visitors a month and a 55% checkout conversion rate, he closes 550 sales at FCFA 15,000. But 24% of his buyers are on MTN, Moov or Airtel and drop off for lack of an option. He installs a multi-operator selector with auto-detection: conversion rises from 55% to ~61% (+11% relative). Result: ~610 sales, 60 more orders a month, +FCFA 900,000 in monthly revenue, for a 2-day one-time integration.

FAQ
How many customers do you lose with a single operator?
About 24% of buyers are on a network different from your default. Offering them their own wallet via a multi-operator selector typically lifts checkout conversion by +11%.
Is network auto-detection reliable?
Yes, around 96% accuracy from the phone prefix. The customer can always correct it manually, and the USSD fallback covers remaining cases and feature phones.
Do I need to integrate six different APIs?
No. One API abstraction (aggregator or unified module) exposes Wave, OM, MTN, Moov, Airtel and M-Pesa behind a common interface. The site-side integration usually fits in 2 days.
Is USSD fallback still useful in 2026?
Yes, for feature phones and users without a wallet app installed. It reduces payment failures and avoids losing a payment-ready customer.
