The verdict in three sentences
On a Ghanaian store, MTN MoMo Collections will cost you roughly 1% plus the e-levy context, but the real expense line is the 8 to 15 days of engineering for a direct API. Going through an aggregator puts you live in 2 to 3 days at the price of an extra commission margin. The right call depends on your monthly volume: below the equivalent of 3,000,000 FCFA in sales, the aggregator almost always wins.
MTN MoMo fees and limits in 2026
Before writing a line of code, frame the real fees and caps. The figures below are a 2026 order of magnitude, to confirm in your MTN merchant contract.
| Parameter | 2026 value (order of magnitude) |
|---|---|
| Merchant Collections fee | ~1% (Ghana) / 1.5-2.5% (Cameroon) |
| Customer wallet cap | 500,000 FCFA equiv. / day |
| Merchant KYC / validation | 3 to 5 business days |
| Collections API dev | 8 to 15 days |
| Direct API dev cost | 400,000 to 900,000 FCFA equiv. |
| Webhook callback delay | < 5 seconds |
| Network failure rate | 4 to 7% |
| Settlement | T+1 to T+2 |
A 4 to 7% failure rate is not trivial: across 1,000 orders that is 40 to 70 transactions to retry. A reliable webhook and a retry mechanism are therefore mandatory, not optional.
Direct API or aggregator: the real math
The question is not "which rate is lowest" but "at what volume does the direct API pay for itself". Let's compare over a year, with Cameroon in parallel (MTN MoMo fees ~1.5-2.5%, settlement T+2).
| Criterion | Direct API | Aggregator |
|---|---|---|
| Per-transaction fee | 1 to 2.5% | 2.5 to 3.5% |
| Time to live | 8 to 15 days | 2 to 3 days |
| Upfront dev cost | 400,000 to 900,000 FCFA | 80,000 to 200,000 FCFA |
| Reconciliation | build it | provided |
| Multi-wallet | one per integration | several at once |
| Maintenance | on you | shared |
On the equivalent of 2,000,000 FCFA in monthly sales, the commission gap (~1%) is 20,000 FCFA/month, or 240,000 FCFA/year — far less than the extra cost of building a direct API. The switch becomes worthwhile above 3,000,000 FCFA equivalent in monthly GMV.
Mini case study
Kwame, who runs a cosmetics store in Accra, sells the equivalent of 1,800,000 FCFA/month. On an aggregator at 3%, he pays 54,000 FCFA in monthly fees. On a direct API at 2%, he would pay 36,000 FCFA, saving 18,000 FCFA per month — but the API would cost 650,000 FCFA to build. Payback: 36 months. Verdict: at his volume, the aggregator is clearly the right call; he will reassess at 3,500,000 FCFA/month.

FAQ
How long until I get paid after a sale?
MTN MoMo settlement runs around T+1 in Ghana in 2026. Expect 1 to 2 business days between a paid order and funds available on your merchant account.
Can the webhook miss a confirmation?
Yes, with a 4 to 7% network failure rate. That is why every webhook must be backed by a queryable status-check endpoint plus an automatic retry 2 to 3 times.
What is my customers' cap?
The customer wallet cap is around the equivalent of 500,000 FCFA/day. For a higher average basket, plan splitting or a card/transfer alternative.
Can I reuse the same integration in Cameroon?
Partly: the MTN MoMo API is close, but fees (1.5-2.5%) and T+2 settlement differ. A multi-country aggregator simplifies this kind of expansion.
Do I need a merchant account separate from my personal wallet?
Yes. Merchant KYC (3 to 5 days) is required to access Collections, signed webhooks, and caps suited to a commercial activity.
