The verdict in three sentences
For a London business collecting payments in West Africa, the best gateway is the one that covers Wave and Orange Money at the lowest rate, settles funds within 24 to 72 hours and plugs into your back-office software to reconcile every payment automatically. On about 1.55 million GBP (1.2 billion FCFA) collected a year, the gap between an average fee of 1.2% and 2.5% is worth more than 19,500 GBP. Integration costs 1,950 to 3,900 GBP (1.5 to 3 million FCFA) and pays back within the first collection cycle through lower arrears and fewer manual hours.
Comparing fees by payment method
In Senegal, payers use mobile money first, bank transfer second, and cards rarely. Real cost depends on the payment mix, not on the headline rate on the aggregator's homepage.
| Payment method | Typical share of payers in Dakar | 2026 fee (order of magnitude) | Settlement time |
|---|---|---|---|
| Wave (merchant API) | 45 to 60% | 1% | 24 h |
| Orange Money | 15 to 25% | 1 to 1.5% | 24 to 48 h |
| Free Money | 3 to 8% | 1 to 2% | 48 h |
| Local bank card (GIM-UEMOA, Visa) | 5 to 10% | 2.5 to 3.5% | 48 to 72 h |
| International card (diaspora) | 3 to 8% | 3 to 3.5% | 72 h or more |
| Bank transfer | 10 to 20% | Fixed bank charges | Variable |
A local aggregator bundling all these methods often charges 1.5 to 2.5% on average. A direct Wave contract for most flows, plus an aggregator for cards, often brings the average down to 1.2 to 1.4%.
Local aggregator, international gateway or hybrid setup
| Criterion | Local aggregator | International gateway | Hybrid (direct Wave + aggregator) |
|---|---|---|---|
| Weighted average fee | 1.5 to 2.5% | 2.9 to 3.5% | 1.2 to 1.6% |
| Mobile money | Wave, Orange Money, Free Money | Often missing | Full |
| Diaspora (foreign cards) | Fair | Excellent | Fair to good |
| Integration cost | 1,950 to 2,850 GBP | 2,600 to 3,900 GBP | 2,850 to 3,900 GBP |
| Back-office reconciliation | Via webhooks | Via webhooks | Via unified webhooks |
| Setup time | 4 weeks | 6 to 8 weeks | 6 weeks |
The hybrid setup needs slightly more development, but it delivers the best cost at volume. The non-negotiable point: reliable confirmation webhooks that update the payer record as soon as payment clears, with a unique reference per student and per instalment. A UK entity will also need a local merchant account or a licensed partner in the UEMOA zone, and should check repatriation rules with its bank.
What the integration must include
A good 6-week project delivers a payer portal (pay by instalment or in full, automatic PDF receipt), automatic reconciliation in your back office, SMS and WhatsApp reminders before each due date, and a finance dashboard per cohort. The 80 monthly hours of keying and receipt matching disappear, and the accountant focuses on disputed cases.

James, CFO of a London education services company, collects tuition for 1,600 students at partner schools in Dakar (1.2 billion FCFA, about 1.55 million GBP a year). Today payments arrive as cash and Wave transfers to a local staff number, with 9% arrears.
With a hybrid setup: 720 million FCFA via Wave at 1% (7.2 million), 240 million via Orange Money and Free Money at 1.3% (3.1 million), 96 million by card at 3% (2.9 million), the rest by transfer. Annual cost: about 13.2 million FCFA (17,100 GBP), plus 2.5 million FCFA (3,250 GBP) of integration. On the other side, automated reminders cut arrears from 9% to 5%, meaning 48 million FCFA (62,000 GBP) collected more or earlier, and 80 monthly hours of keying removed. The project pays back within the first term.
FAQ
Can we pass the fee on to payers?
Technically yes, but it is poorly received. Most organisations absorb it, since 1.2% on 750,000 FCFA (975 GBP) of tuition is 9,000 FCFA (12 GBP), offset by lower arrears.
How do we handle diaspora payers?
With an international card option at 3 to 3.5%. It often covers 3 to 8% of families, but those payments are regular and on time.
Does our back-office software need an API?
Ideally, yes. Otherwise a daily automated export and import works, at an extra 390 to 780 GBP.
How long to be ready for the new term?
Allow 6 weeks, including 2 for merchant account opening and compliance. Starting in July means being live for October.
