Payment Aggregator vs Direct Wave Integration: Which Really Costs Less in 2026?

The verdict in three sentences

An aggregator costs more per transaction (2.5–3.5 %) but far less to start because it replaces three separate integrations (Wave, Orange Money, cards). Direct Wave integration drops to around 1 % in fees but demands 10 to 20 developer-days per operator plus webhook maintenance. The tipping point sits around 2,000,000 FCFA in monthly volume: below it the aggregator wins; above it, the margin recovered on fees more than pays for direct dev.

Fees, delay, settlement: head to head

The difference is not only about the percentage skimmed. Onboarding time, settlement speed (payout to your account) and support weigh just as much on a small shop's cash flow.

At modest volume, the extra 2 to 3 fee points of the aggregator stay below the cost of a developer for three weeks. It is the classic inversion between fixed cost and variable cost.

The tipping point in figures

Assume a direct dev cost estimated at 1,500,000 FCFA (about 15 days) to integrate Wave alone, amortized over 12 months. On top of that dev sits the fee gap you recover each month.

These amounts are a 2026 order of magnitude: your real rate depends on the merchant contract negotiated and the card vs mobile-money mix. Keep the logic: direct becomes profitable once the monthly fee gap exceeds the dev amortization.

Mini case study

Awa runs a cosmetics shop in Dakar with 1,200,000 FCFA in online sales per month. With an aggregator at 3 %, she pays 36,000 FCFA/month in fees. On direct Wave at 1 %, she would pay 12,000 FCFA/month, saving 24,000 FCFA. But direct dev would cost her 1,500,000 FCFA, repaid in 62 months at that pace. Verdict: at her volume, the aggregator is the right call. She will switch to direct once she clears 5,000,000 FCFA/month.

FAQ

Does an aggregator also charge fixed fees?

Often yes, a small flat fee per card transaction (say 100 FCFA) on top of the percentage. On small baskets, that fixed part can weigh as much as the percentage, so check the schedule.

Can you start with an aggregator then migrate to direct?

Yes, and that is the recommended path. Start on an aggregator to launch fast, then integrate Wave directly once volume passes 5,000,000 FCFA/month to recover 2 points of margin.

Does direct integration cover Orange Money too?

No, each operator is a separate project. Integrating Wave then Orange Money directly is two lots of 10 to 20 dev-days, which pushes the tipping point out.

Is an aggregator's slower settlement a problem?

For a shop with cash reserves, T+7 settlement is manageable. For a business restocking every week, a direct T+1 can be worth the extra fee points.
