Integrating MTN MoMo and Paystack checkout for a Lagos store (2026)

The verdict in three sentences

A dual MTN MoMo + Paystack button covers roughly 90 % of Nigerian mobile traffic and sharply cuts drop-off at the moment of payment. MTN MoMo charges around 1 % merchant fee, Paystack around 1.5 %, but they are complementary because each captures customers the other misses. With an average basket near NGN 24,000 and 78 % of payments on mobile, a well-wired native checkout is the most profitable conversion lever a Lagos store has.

Two flows, two logics

MTN MoMo and Paystack do not trigger the same way on mobile. MoMo leans on a USSD prompt plus an approval PIN, while Paystack drives a hosted card/transfer page with an app deep link. Understanding these differences avoids breaking the journey on the older Android devices that still dominate.

Confirmation delay matters: between tapping "Pay" and the webhook return, expect 3 to 8 seconds. During that window the screen must show a clear "payment in progress" state, otherwise the customer retries and creates a duplicate.

What a native button changes

Wiring a real native button instead of a bank-transfer note transforms the numbers. On the Lagos stores we track in 2026, the gap is stark.

Halving abandonment nearly doubles mobile conversion without spending a single naira more on acquisition.

Mini case study

Fatou runs a cosmetics store in Lagos. Before, she posted a bank-transfer note: 300 orders/month, but 46 % abandoned at payment, roughly 255 lost attempts. After adding the dual MoMo + Paystack button, abandonment dropped to 23 %. On the same traffic she recovers about 70 extra orders per month at NGN 24,000, i.e. NGN 1,680,000 additional monthly revenue. Paystack fees (1.5 %) on that surplus are about NGN 25,200: the integration pays for itself in under a month.

FAQ

Do I really need both buttons, or is one enough?

MoMo covers ~55 % of customers, Paystack ~65 %, with strong overlap. Offering both pushes coverage to about 90 %: each customer pays with the tool they already have, which cuts abandonment.

How long does integration take?

For a standard store, plan 3 to 6 working days including webhook testing in a sandbox. The most delicate part is asynchronous payment confirmation, which must be tested with real amounts.

What happens if the webhook never arrives?

You need a fallback that queries the status API after 10 seconds, plus a retry queue. Without it, a successful payment may never mark the order as paid.

Is the NGN 24,000 basket realistic?

It is a 2026 order of magnitude seen on fashion and cosmetics stores in Lagos. Electronics stores run far higher, groceries often dip below NGN 15,000.

Can I add cards later?

Yes. A unified module lets you add international card payments without touching the existing mobile money flow.
