The verdict in three sentences
A multi-step checkout kills your conversion: every extra page drives away 10 to 15 % of mobile buyers. Moving from 3 steps to a single page with a pre-selected wallet and a deep link into the operator's app delivers +22 % conversion and drops payment time from 40 s to 12 s. The real lever is not design but removing input friction.
Why mobile money abandons so much
Average MoMo abandonment in Ghana sits between 55 and 68 % (2026 order of magnitude), above the card average. The causes are mechanical: re-typing the number, manually switching to the MTN MoMo or Telecel Cash app, waiting for the USSD prompt, returning to the site. Every app switch costs seconds and buyers.
| Classic checkout step | Average time | Cumulative abandonment |
|---|---|---|
| Page 1 — cart + login | 18 s | 12 % |
| Page 2 — shipping address | 25 s | 28 % |
| Page 3 — payment choice | 15 s | 41 % |
| Operator app switch (USSD) | 40 s | 58 % |
| Return to site + confirm | 12 s | 63 % |
With a 4-5 screen funnel, nearly two thirds of potential revenue evaporates before confirmation.
The one-page pattern that wins
The principle: everything on one screen, the most likely wallet pre-ticked from history or IP, and a single button that opens the payment app directly via deep link. No more manually typed USSD.
| Optimisation | Before | After | Conversion gain |
|---|---|---|---|
| Number of pages | 3 | 1 | +22 % |
| Pre-selected wallet | no | yes | +9 % |
| MoMo deep link | no | yes | +14 % |
| Fields requested | 11 | 5 | +7 % |
| Total payment time | 40 s | 12 s | -70 % time |
| Auto-filled number | no | yes | +6 % |
Stacked together, these settings turn a 3.2 % mobile conversion rate into 4.5-5 % without touching traffic or price.

Mini case study
Akosua runs a cosmetics store in Accra. She gets 2,400 visitors/month, an average basket of GHS 220, and an old conversion rate of 3.1 % — about 74 orders and GHS 16,280/month. After rebuilding to a one-page checkout with an MTN MoMo deep link, conversion climbs to 3.9 %: 94 orders, or GHS 20,680/month. Net gain: +GHS 4,400/month, roughly +GHS 52,800/year for a rebuild paid back in under three weeks.
FAQ
Does the deep link work with MTN MoMo and Telecel Cash? Yes. MoMo exposes payment links that open the app directly, and web redirect flows exist for the main wallets. The customer confirms in-app then returns automatically to the success page via webhook.
Should I force account creation? No — guest checkout is essential: forcing an account before payment costs 15 to 20 % conversion on average. Offer account creation after the order.
How many fields are truly needed? Five: name, phone, city, short address, wallet. Each superfluous field removed adds roughly 1 to 2 % conversion.
Does a one-page checkout slow loading? Not if you prioritise visible content and optimise for slow networks. A checkout page should render in under 2 s even on 3G.
What about payments that still fail? Trigger an automatic SMS then WhatsApp retry within 15 minutes: 25 to 38 % of temporary failures are recovered this way.
