The verdict in three sentences
Integrating Wave, Orange Money, MTN and Moov directly is 4-8 weeks of development and four systems to maintain. An aggregator collapses that into one contract, one unified webhook and a single reconciliation format. You pay 0.5 to 1.5 % more in fees, but you ship in days instead of six weeks.
Build vs buy: the real math
Each operator has its own API, webhook schema, auth logic and edge cases (USSD timeout, double notification, partial refund). Multiplied by four, it becomes a project in its own right.
| Criterion | Direct integration (4 operators) | Single aggregator |
|---|---|---|
| Time to production | 4-8 weeks | 3-7 days |
| Dev cost (2026 order) | 300,000-600,000 FCFA/operator | 150,000-400,000 FCFA total |
| Webhooks to handle | 4 distinct schemas | 1 unified schema |
| Reconciliation | 4 formats | 1 format |
| Fee per transaction | 1.0-1.9 % | 1.5-3.0 % |
| Failover between operators | code it yourself | included |
| Annual maintenance | high (4 SDKs) | low (1 SDK) |
The simple rule: below very high volume, the aggregator almost always wins on total cost of ownership. Above it, direct integration can become worthwhile again to reclaim the 0.5-1.5 % margin.
What an aggregator actually unifies
The gain isn't only dev time. It's operational consistency over the long run.
| Function | Without aggregator | With aggregator |
|---|---|---|
| Webhook format | 4 different payloads | 1 normalised payload |
| Payment statuses | per-operator vocabulary | standard statuses (paid, pending, failed) |
| Geographic coverage | negotiate country by country | West + East Africa in one contract |
| New payment method | new project | enable by config |
| Failover if operator down | lost sales | automatic rerouting |
On coverage, a serious aggregator opens up Wave, Orange Money, MTN MoMo, Moov in 2026, plus M-Pesa and Airtel Money on the East Africa side — with zero extra development.

Mini case study
Ibrahim, developer of a delivery platform in Abidjan, had budgeted 6 weeks to wire up Wave, Orange, MTN and Moov, roughly 4 × 400,000 = 1,600,000 FCFA of dev. Going through an aggregator at 300,000 FCFA, he ships in 5 days. The transactional surcharge (about +1 % on 10,000,000 FCFA of monthly volume, i.e. 100,000 FCFA/month) is absorbed the moment he counts the dev time and the maintenance of four SDKs saved: he recoups the investment in under two months.
FAQ
How much time do you really save with an aggregator? In practice you go from 4-8 weeks to 3-7 days. Most of the saving comes from the webhooks and edge cases the aggregator has already solved for each operator.
Is the 0.5 to 1.5 % surcharge worth it? At mid volumes, yes: total cost of ownership (dev + maintaining 4 SDKs) far exceeds the transactional surcharge. Above very high volume, you re-evaluate direct integration.
What is automatic failover? If Orange Money is unavailable, the aggregator reroutes the transaction to another compatible operator, avoiding the lost sale. Direct, you'd have to code that logic yourself.
Does an aggregator cover East Africa? Yes, serious 2026 aggregators cover M-Pesa and Airtel Money on top of West African operators, under the same contract and webhook.
Can you migrate to direct later? Yes. Many start on an aggregator to ship fast, then move some operators to direct once volume justifies reclaiming the margin. The unified webhook eases that transition.
