The verdict in three sentences
For a store in Ghana, integrating MTN MoMo, Paystack and Flutterwave directly gives the lowest fees but demands 2 to 4 weeks of development and roughly 350,000 FCFA per provider, plus maintaining multiple webhooks. A single aggregator puts you live in 3 days at 1.8 to 3.5% per transaction, with one webhook and native retry that drops the failure rate from 8-12% to 4-6%. The right answer depends on volume: under about 8 to 10 million FCFA in monthly sales, the aggregator almost always wins.
Direct or aggregator: the real math
Direct integration looks great on paper because MTN and mobile money rails sit around 1.5%. But you must add the upfront dev cost, the maintenance of each API, and above all the lost revenue from payments that fail with no retry mechanism.
| Criterion | Direct integration | Single aggregator |
|---|---|---|
| Time to go live | 2 to 4 weeks / provider | 3 days |
| Upfront dev cost | ~350,000 FCFA / provider | 0 to 150,000 FCFA |
| Fee per transaction | 1 to 3.5% | 1.8 to 3.5% |
| Webhooks to maintain | 3+ | 1 |
| Observed failure rate | 8 to 12% | 4 to 6% |
| Automatic retry | code it yourself | included |
| Reconciliation | multiple dashboards | one dashboard |
Fees and settlement per provider (2026)
Fees tell only half the story: the settlement delay weighs on your cash flow. Here is the 2026 order of magnitude for a Ghanaian merchant.
| Provider | Estimated 2026 fee | Settlement | Notes |
|---|---|---|---|
| MTN MoMo | ~1.5% | T+2 | dominant in Ghana |
| Paystack | 1.5% + 100 NGN (cap 2,000 NGN) | T+1 | strong webhook |
| Flutterwave | ~1.4% | T+1 to T+2 | multi-country |
| Cards (Visa/MC) | 2.9% + fixed | T+2 to T+3 | international |
| Via aggregator | 1.8 to 3.5% all-in | T+1 to T+2 | all rails |
An aggregator smooths these delays: you get a consolidated payout, often T+1 or T+2, instead of tracking several separate flows.
Mini case study
Kwame runs a cosmetics store in Accra with 6,000,000 FCFA in monthly sales and a 12,000 FCFA average basket, about 500 transactions. Direct, he pays roughly 1.4% in fees (84,000 FCFA/month) but his 10% failure rate loses about 50 unrecovered orders, some 600,000 FCFA in evaporated sales. Through an aggregator at 2.5% (150,000 FCFA/month) with retry, failures drop to 5%: he recovers ~30 extra orders, about 360,000 FCFA more. Net: he pays 66,000 FCFA more in fees but banks 360,000 FCFA more in sales. Net gain: +294,000 FCFA per month.

Which aggregator covers the most rails in Ghana?
Flutterwave and Paystack cover MTN MoMo plus cards and bank transfers. Expect 1.5 to 2.5%, negotiable above 10,000,000 FCFA of monthly volume.
At what volume does direct integration pay off?
As a 2026 order of magnitude, above 25 to 30 million FCFA in monthly sales the fee gap (a point or more) eventually covers the dev and maintenance cost. Below that, the aggregator stays cheaper.
Does Paystack's cap really matter?
Yes: the 2,000 NGN cap means large baskets pay a flat, predictable fee, which protects margin on high-ticket items.
Is a single webhook really safer?
Yes: one entry point means one signature check, one idempotency logic and unified reconciliation. You cut the bug surface dramatically.
How long to wire an aggregator into an existing site?
Usually 3 to 5 business days: API key, checkout page, signed webhook endpoint and end-to-end tests across every provider.
