The verdict in three sentences
In Accra, an MTN MoMo merchant checkout converts roughly twice as well as card payment because it removes card-number entry on mobile. The recommended stack is Next.js + Supabase: fast on 3G, secure and ready for MTN MoMo, Vodafone Cash and AirtelTigo Money. Go-live takes 10 to 15 days and the first-year total lands around GH₵35,000 to GH₵50,000, all in.
Why MoMo checkout converts better
The number-one e-commerce blocker in Accra is not traffic, it is payment abandonment. Here is the channel impact on conversion (2026 order of magnitude).
| Payment channel | 2026 fee | Checkout conversion | Typical abandonment |
|---|---|---|---|
| MTN MoMo | ~1 % | 55–70 % | Low |
| Vodafone Cash | ~1.5 % | 45–60 % | Medium |
| AirtelTigo Money | ~1.5 % | 40–55 % | Medium |
| International card | 2.9 % + fixed | 20–35 % | High |
| Cash on delivery | 0 % | 50–65 % | High returns |
On 1,000 qualified visitors and a GH₵400 basket, moving from 30 % (card) to 60 % (MoMo) lifts revenue from GH₵120,000 to GH₵240,000. That is where profitability is won.
