The verdict in three sentences
In Douala, the integration development cost (350,000 to 900,000 FCFA) is one-off, but the 1.5 to 2.2 % transaction fees are forever and weigh far more heavily as volume grows. The MTN MoMo Collection API requires a merchant account approved in 2 to 4 weeks plus technical onboarding often missing from budgets. In Lagos, Paystack and Flutterwave flip the logic: free signup, 1.5 % + 100 NGN capped at 2,000 NGN on local cards, but pricier international cards.
What you really pay in Cameroon
The classic trap is believing the developer quote equals the total cost. In reality three cost layers stack up — the dev once, per-transaction fees forever, and withdrawal/settlement fees.
| 2026 item (Douala) | MTN MoMo Collection | Orange Money CM |
|---|---|---|
| Setup / activation fee | 0 FCFA (but paperwork) | 0 FCFA (but paperwork) |
| Per-transaction fee | 1.5 to 2.2 % | 1.5 to 1.8 % |
| Merchant activation delay | 2 to 4 weeks | 2 to 3 weeks |
| Payout / settlement | T+1 to T+3 | T+1 to T+2 |
| Integration dev cost (est.) | 350,000 to 900,000 FCFA | 300,000 to 800,000 FCFA |
| Confirmation webhook | Yes (harden it) | Yes (harden it) |
2026 order of magnitude: exact rates depend on your volume negotiation and company status.
Douala vs Lagos: two cost models
Nigeria has a more mature aggregator ecosystem, which radically changes the cost structure for a startup.
| 2026 criterion | Douala (MoMo/OM) | Lagos (Paystack/Flutterwave) |
|---|---|---|
| Signup | Merchant paperwork | Free, online |
| Local card fee | n/a (mobile money) | 1.5 % + 100 NGN, cap 2,000 NGN |
| Mobile money fee | 1.5 to 2.2 % | 1.5 to 1.95 % |
| Go-live delay | 2 to 4 weeks | 1 to 3 days |
| Payout | T+1 to T+3 | T+1 |
| Dev documentation | Decent | Excellent |
Mini case study
Take Marlyse, who runs a cosmetics shop in Douala, targeting 4,000,000 FCFA of online sales per month. At an average 2 % fee, she pays 80,000 FCFA/month in commissions, or 960,000 FCFA/year. If her integration cost 600,000 FCFA once, recurring fees overtake the dev cost by month 8. Conclusion: negotiating 0.3 point off (from 2 % to 1.7 %) saves her 144,000 FCFA/year — more profitable than cutting dev quality.

FAQ
Do you need a registered company for the MTN MoMo API in Cameroon?
Yes. Activating a Collection merchant account requires legal paperwork (trade register, manager ID) and the realistic delay is 2 to 4 weeks in 2026. Build that buffer into your launch plan.
Does Paystack work for a Cameroonian merchant?
Paystack mainly targets Nigeria, Ghana, South Africa and Kenya. For Cameroon in 2026 you rely on direct MoMo/OM APIs or a regional aggregator. Always check country coverage before choosing.
Is the confirmation webhook really essential?
Yes, it is critical. Without a reliable webhook you risk shipping an unpaid order or blocking a customer who did pay. Budget a meaningful share of dev for testing this flow in real conditions.
What total budget for the first year in Douala?
2026 order of magnitude: 350,000 to 900,000 FCFA of dev, plus 1.5 to 2.2 % of your sales in fees. For 3,000,000 FCFA/month of volume, that adds roughly 540,000 to 792,000 FCFA of annual fees on top of dev.
