The verdict in three sentences
The average cart-abandonment rate in Africa hovers around 68 %, and every unnecessary step worsens the leak. Cutting checkout from 5 to 2 screens and adding an MTN MoMo / Orange Money deeplink instead of a USSD code sharply lifts mobile conversion. For an average store in Kampala, the estimated gain is 300,000 to 900,000 FCFA of recovered monthly revenue.
Where the funnel actually leaks
The problem is almost never price: it's friction. Too many fields, a USSD code to retype, a late OTP, a page that reloads. Every second counts on 3G mobile. Here is the measured impact of each lever.
| 2026 lever (estimate) | Effect on conversion |
|---|---|
| 2-step vs 5-step checkout | -15 points of abandonment |
| MoMo/OM deeplink vs manual USSD | +18 % conversion |
| Pre-filled number + name | -8 s of typing |
| Average OTP entry | 22 s |
| Guest checkout (no account) | +11 % orders |
| Order summary visible at payment | -6 % abandonment |
The short funnel, step by step
The goal: a single page where the customer sees their cart, enters their number and triggers payment in one tap. The deeplink opens the MTN MoMo or Orange Money app directly with the amount pre-filled — no code to retype.
| Step | Long funnel (5 screens) | Express funnel (2 screens) |
|---|---|---|
| 1 | Cart | Cart + contact details |
| 2 | Login / account | Payment (deeplink) |
| 3 | Address | — |
| 4 | Payment choice | — |
| 5 | OTP confirmation | — |
| Estimated abandonment | ~68 % | ~53 % |
Mini case study
Rachid, who runs an accessories shop in Kampala, gets 1,200 visitors/month at a 1.4 % conversion rate — 17 orders at 30,000 FCFA (510,000 FCFA). Switching to a 2-step checkout with an MTN MoMo deeplink lifts conversion to 2.1 %: 25 orders, i.e. +240,000 FCFA/month. Over a year that's nearly 2,900,000 FCFA recovered for a one-off optimization spend.

Why does the deeplink convert better than USSD?
Because it removes manual re-entry of the code and amount. The customer taps once and the app opens pre-filled: the estimated gain is about +18 % conversion.
Is a 2-step checkout really enough?
Yes, if you group cart and contact details on one screen and payment on the other. We see up to -15 points of abandonment versus a 5-screen funnel.
Should I force account creation?
No. Guest checkout adds about +11 % orders. Offer account creation after the purchase, not before.
How long to rebuild my funnel?
Usually 3 to 6 days depending on the platform. The return on investment shows up in the first month through the higher conversion rate.
