The verdict in three sentences
When you sell in a single country, integrating Wave and Orange Money directly pays off and keeps your rate lowest. The moment you target four or five countries, each direct operator adds 2-4 weeks of development plus permanent maintenance, and the single aggregator often becomes the better choice despite its 0.3-0.7% markup. The real question isn't "which is cheapest" but "at how many countries does engineering time cost more than the markup".
Integration effort, operator by operator
A direct integration is more than an API call: you need the confirmation webhook, reconciliation, failure cases, refunds and end-to-end tests. Here is a 2026 order of magnitude for a team that already knows the domain.
| Operator / country | Direct dev effort | Webhooks to run | Yearly maintenance |
|---|---|---|---|
| Wave (SN, CI) | 2-3 weeks | 1 flow | ~4 d/yr |
| Orange Money (SN, CI, ML) | 3-4 weeks | 1 flow + USSD retry | ~6 d/yr |
| MTN MoMo (CI, BJ) | 3 weeks | 1 flow | ~5 d/yr |
| Moov Money (CI, BJ, TG) | 2-3 weeks | 1 flow | ~4 d/yr |
| 4 operators direct | 10-13 weeks | 4 separate flows | ~19 d/yr |
| Single aggregator | 1-2 weeks | 1 unified flow | ~3 d/yr |
With the aggregator you wire one webhook and one reconciliation path, whatever the number of countries. Direct, each operator has its own status semantics, settlement delays and signature formats.
Total cost of ownership over 24 months
The aggregator markup is paid on volume; the direct integration is paid in engineer salaries. We compare a merchant processing 30,000,000 FCFA/month across 4 countries, with a loaded dev cost of 250,000 FCFA/week.
| Line item | Direct integrations | Single aggregator |
|---|---|---|
| Initial build (weeks) | 11 wk → 2,750,000 FCFA | 1.5 wk → 375,000 FCFA |
| Average operator fee | 1.5% | 1.5% |
| Aggregator markup | 0% | +0.5% |
| Monthly fees on 30M | 450,000 FCFA | 600,000 FCFA |
| Maintenance / year | 19 d → 950,000 FCFA | 3 d → 150,000 FCFA |
| Total cost 24 months | ~14,550,000 FCFA | ~14,775,000 FCFA |
At this volume the two converge: the markup overhead (3.6M over 24 months) is almost offset by build and maintenance savings (3.4M). Below 15,000,000 FCFA/month the aggregator wins clearly; above 60,000,000 FCFA/month direct becomes cheaper again.

Fatou, founder of a cosmetics brand in Dakar, already sells in Senegal and wants to open in Côte d'Ivoire, Mali and Benin within six months. Direct, her vendor estimates 11 weeks of dev — a full quarter of launch delay. She picks an aggregator: all 4 countries live in 12 days. On her 8,000,000 FCFA/month volume, the 0.5% markup costs her 40,000 FCFA/month, versus 2,750,000 FCFA of dev avoided. The math is quick: she reinvests that saved quarter into acquisition.
FAQ
Does an aggregator lock me into a single provider?
Yes, that's the real risk. Isolate it behind your own PaymentService layer: if you switch aggregators or add direct later, only the adapter changes, not your checkout. Budget 1-2 weeks for that abstraction — it pays for itself.
Is the 0.5% markup negotiable?
Often yes above 50,000,000 FCFA/month of volume: aggregators drop to 0.3% or even waive the monthly minimum. Below that, expect list pricing and a floor of 10,000 to 25,000 FCFA/month.
Can I mix direct and aggregator?
That's the ideal hybrid: Wave and Orange Money direct in your main country (lowest rate), aggregator for low-volume secondary countries. You optimize cost where volume justifies it.
How long to add a 5th country afterward?
With the aggregator: a few hours of configuration if the operator is already covered. Direct: an extra 2-4 weeks per operator, every time.
