The verdict in three sentences
MTN MoMo in Kumasi runs on the Collection API under GhIPSS interoperability, with merchant KYC to launch first — that is the real critical path, not the code. Expect merchant fees around 1 % and daily settlement, helped by the e-levy removal since April 2025. Plan for the Disbursement API from the start to handle refunds cleanly.
Enabling the Collection API in Kumasi
MTN's Collection API collects by triggering a PIN prompt on the customer's phone. Before any code, you must clear merchant KYC: business registration, ID of the operator. This administrative delay sets your go-live date, so start it first.
| Element | Ghana 2026 value | Note |
|---|---|---|
| Merchant fee | ~1 % | Post e-levy removal |
| E-levy | Removed April 2025 | Was 1 % |
| Interoperability | GhIPSS full | Cross-network |
| Settlement | Daily | Cash flow friendly |
| PIN prompt completion | ~74 % (est.) | Depends on UX and network |
| Confirmation | Webhook | Never the browser return |
GhIPSS interoperability means a customer on another network can still pay your MTN till, which widens your reachable base compared with a single-operator setup.
Ghana vs Cameroon: two different regimes
If you operate on both sides, MTN MoMo does not follow the same rules in Ghana and Cameroon. Cameroon keeps a per-transaction cap and slightly higher fees.
| Criterion | MTN MoMo Ghana | MTN MoMo Cameroon |
|---|---|---|
| Merchant fee | ~1 % | 1.5 to 2 % |
| E-levy | Removed April 2025 | Not applicable |
| Interoperability | GhIPSS full | Partial |
| Transaction cap | Per GHS tiers | 500,000 FCFA |
| Settlement | Daily | Per agreement |
| PIN completion | ~74 % | ~74 % |
Ghana is currently slightly cheaper on the merchant side thanks to the e-levy removal, a point to weigh if you arbitrate between the two markets.
Mini case study
Kwame runs a fashion store in Kumasi, average cart GHS 400, 350 attempts a month. With a PIN prompt completed at 74 %, he makes 259 sales (GHS 103,600). By clarifying the waiting message and pre-filling the MTN number, he gains 5 points (79 %), or 277 sales (GHS 110,800). Monthly gain: GHS 7,200. MTN fee at 1 % on new sales: GHS 72. Launching KYC early saved him a week of go-live time.

FAQ
Where do I start to enable MTN MoMo?
With merchant KYC, which takes several days. It is the critical path: launch it before coding the integration so it does not delay go-live.
What changed with the e-levy?
Ghana removed the 1 % e-levy in April 2025, lowering the effective cost of mobile money payments and making MTN MoMo cheaper for merchants and customers alike.
What merchant fees should I expect?
Around 1 % in Ghana post e-levy removal. Cameroon sits at 1.5 to 2 % with a 500,000 FCFA per-transaction cap.
How do I refund a customer?
Through MTN's Disbursement API, with its own fees and timing. Build the refund logic in from the start rather than bolting it on later.
Why only 74 % of PIN prompts completed?
Network, customer hesitation, PIN entry. A clear waiting message and a pre-filled number easily recover 4 to 5 points of completion.
