The verdict in three sentences
Direct integration of a mobile money API minimizes fees (~1%) but puts merchant KYC, signed webhooks and reconciliation on you. The aggregator delivers a turnkey multi-provider SDK in days, at 1.5 to 2.5%. The switch is a volume question: below ~15,000,000 FCFA/month, the aggregator wins; above it, direct becomes profitable.
Direct vs aggregator: the decision matrix
Direct optimizes marginal cost; the aggregator optimizes time-to-market and maintenance load.
| Criterion | Direct integration | Aggregator |
|---|---|---|
| Network fees | ~1% | 1.5–2.5% |
| Integration time | 3–6 weeks | 3–5 days |
| Providers covered | 1 per integration | multi-provider |
| Merchant KYC | on you | handled |
| Webhooks / reconciliation | to code | provided |
| Maintenance | high | low |
| Profitable volume threshold | > 15,000,000 FCFA/month | < 15,000,000 FCFA/month |
2026 technical integration checklist
Whether you go direct or via aggregator, these are non-negotiable on the code side.
| Technical item | 2026 recommendation | Why |
|---|---|---|
| Sandbox | use before prod | test without real movement |
| Webhook signature | HMAC required | block fake callbacks |
| Timeout / retry | 3 attempts | unstable mobile network |
| Idempotency | key per transaction | avoid duplicates |
| Reconciliation | daily job | detect discrepancies |
| Statuses handled | pending/success/failed/expired | clear UX |
Mini case study
Cheikh, lead dev of a delivery startup in Dakar, processes 9,000,000 FCFA/month in payments. Direct at 1%, his network fees would be 90,000 FCFA/month, but that means ~5 weeks of dev plus webhook maintenance. Via an aggregator at 2%, he pays 180,000 FCFA/month but launches in 4 days. As long as his volume stays under 15,000,000 FCFA, the aggregator is the right call: the 90,000 FCFA/month gap does not yet cover the engineering and maintenance cost of going direct.

What is the real fee of a direct mobile money payment?
As a 2026 order of magnitude, the raw network fee sits around 1% merchant-side. The aggregator adds its margin to reach 1.5–2.5%, in exchange for the SDK and operational handling.
How long to integrate Wave or Orange Money directly?
Expect 3 to 6 weeks: obtaining the merchant account, KYC, implementing signed webhooks (HMAC), handling statuses and sandbox testing. An aggregator cuts that to 3–5 days.
At what volume does direct become profitable?
Around 15,000,000 FCFA in monthly volume. Below that, the fee savings do not offset the development and maintenance cost; above it, direct takes the lead.
Is HMAC webhook signing really essential?
Yes. Without HMAC verification, anyone can send a fake "payment successful" callback. It is the minimum protection, alongside a 3-attempt retry and daily reconciliation.
Can you start on an aggregator then migrate to direct?
That is the recommended strategy: launch fast via aggregator, then switch to direct once volume passes the threshold. Good architecture isolates the payment layer to ease migration.
