The verdict in three sentences
A payment gateway in Cameroon is not just its transaction rate: add integration (300,000 to 600,000 FCFA), maintenance (50,000 FCFA/mo) and FX on foreign-currency payments. For a merchant at 2,000,000 FCFA/month, the real effective cost spreads between 2.2 % and 4.1 % of volume depending on options. Ghana offers a more competitive ecosystem (Paystack, Hubtel) that pulls transaction rates down.
Breakdown for 2,000,000 FCFA/month
Simulation on a monthly volume of 2,000,000 FCFA in Cameroon.
| Item | Monthly cost | % of volume |
|---|---|---|
| Transaction fee (1.7 %) | 34,000 FCFA | 1.70 % |
| Integration amortization (450,000 over 12 mo) | 37,500 FCFA | 1.88 % |
| Maintenance | 50,000 FCFA | 2.50 % cumulative |
| FX on 20 % in currency (3 %) | 12,000 FCFA | 0.60 % |
| Withdrawal to bank (0.7 %) | 14,000 FCFA | 0.70 % |
In the first year, integration amortization weighs heavily; it then disappears, pulling the effective cost down from the second fiscal year.
Cameroon vs Ghana
2026 orders of magnitude for gateway options in both countries.
| Option | Country | Transaction rate | Integration | Maintenance |
|---|---|---|---|---|
| MTN MoMo | Cameroon | ~1.5-1.8 % | 300,000-500,000 FCFA | 50,000 FCFA/mo |
| Orange Money | Cameroon | ~1.5-2 % | 350,000-600,000 FCFA | 50,000 FCFA/mo |
| MTN MoMo | Ghana | ~1.0-1.5 % | equivalent | equivalent |
| Paystack | Ghana | ~1.5 % (cap) | low (ready API) | included |
| Hubtel | Ghana | ~1.5-2 % | medium | variable |
In Ghana, Paystack and Hubtel offer ready-made APIs that cut integration cost, whereas Cameroon often demands more custom development.

Brice, an e-merchant in Douala, does 2,000,000 FCFA/month. First year: transaction 34,000 + amortized integration 37,500 + maintenance 50,000 + FX 12,000 + withdrawal 14,000 = 147,500 FCFA/month, an effective rate of 7.4 %... too high. By cutting maintenance to 25,000 FCFA and removing FX (all in FCFA), he drops to 110,500 FCFA the first year, then to 73,000 FCFA (3.65 %) from the second, integration amortized.
FAQ
Why does the effective cost exceed the headline rate so much?
Because integration, maintenance and FX add on top of the transaction rate. In the first year, integration amortization alone can add 1.5 to 2 percentage points.
Is Ghana cheaper than Cameroon?
On integration cost, yes: Paystack and Hubtel offer ready APIs that reduce development. Transaction rates are comparable, around 1.5 %.
How do I reduce the first-year cost?
Spread integration via a partner who mutualizes it, collect in FCFA to avoid FX, and negotiate maintenance. You can save 1 to 2 effective points.
When does the gateway become profitable?
Once integration is amortized (12 months) and volume stabilizes above 1,500,000 FCFA/month, the effective cost approaches the real transaction rate, around 2.2 %.
