The verdict in three sentences
The sale is not lost on the product page, it dies at the payment step. In Kampala in 2026, mobile cart abandonment sits between 65% and 75%, and every extra form field mechanically drops buyers. Moving from a 4-field checkout to a 1-tap mobile-money flow can recover +8 to +15% of conversion (2026 order of magnitude).
Where sales actually die
The stubborn myth is that buyers hesitate on price. In reality, they have already decided: they want to pay. What scares them off is the friction between the "Pay" click and the MTN MoMo or Airtel Money confirmation. On a 3G connection in Kampala, every second of load time beyond 3 seconds costs conversions.
| Friction source | Abandonment impact (2026 estimate) | Cause |
|---|---|---|
| Form with 4+ fields | +15 to +25% | Painful mobile typing |
| Mandatory account creation | +20 to +30% | Barrier for first purchase |
| Payment page > 3s on 3G | +10 to +20% | Load budget blown |
| No status after USSD push | +10 to +15% | Blank screen, panic |
| Broken redirect to operator | +8 to +12% | Lost context |
| Surprise fees at the end | +12 to +18% | Trust broken |
What fixes the checkout, and what it returns
The logic is simple: cut the number of decisions and screens between intent and confirmation. The phone number acts as identity, mobile money triggers a push, and a status page reassures while waiting for the webhook.
| Fix | Effort | Expected conversion gain |
|---|---|---|
| Guest checkout (no account) | Low | +8 to +12% |
| Phone number as identifier | Low | +4 to +7% |
| 1-tap MoMo / Airtel flow | Medium | +6 to +10% |
| Load budget < 3s on 3G | Medium | +5 to +9% |
| "Payment pending" status page | Medium | +3 to +6% |
| Show fees from the cart | Low | +3 to +5% |
Combined, these fixes do not add up linearly, but moving from 4 fields to a 1-tap flow realistically gains +8 to +15% more completed orders.
Mini case study
Awa runs a cosmetics shop in Kampala. On 1,200 mobile sessions per month, her checkout conversion is 2.1%, about 25 orders at an average basket of 18,000 FCFA (approx. 27 EUR) — roughly 450,000 FCFA/month. After removing the mandatory account and switching to a 1-tap MoMo flow, conversion rises to 2.5%, about 30 orders. The 5 recovered orders are +90,000 FCFA/month, or 1,080,000 FCFA/year — for a few days of technical work.

Does guest checkout cost you loyal customers?
No, if you offer account creation AFTER payment. The mobile-money phone number already acts as identifier, and you can turn the guest into an account in 1 post-purchase screen. The gain on first-time buyers (+20 to +30% less abandonment) far outweighs the risk.
How many fields maximum on a mobile checkout?
Aim for 1-2 visible fields: name and phone number. Everything else (shipping address) can come after payment confirmation. Each removed field cuts abandonment by several points.
Why is the 3-second budget critical in Kampala?
Because a large share of traffic is on 3G, even 2G at peak hours. Beyond 3 seconds to load the payment page, abandonment climbs 10 to 20%. Compressed images, no heavy scripts, a light page.
Should MTN MoMo and Airtel Money be shown separately?
Yes, clear clickable logos reassure. The buyer wants to see THEIR operator immediately. A dropdown or hidden choice adds a needless decision and costs conversion.
How long to implement these fixes?
A guest checkout + 1-tap flow + status page is usually delivered in 1 to 2 weeks depending on the existing platform. The return on investment shows from the first month on recovered orders.
