The verdict in three sentences
In Kampala as in Libreville, every extra checkout field kills sales: mobile cart abandonment runs between 60 and 75 % in 2026. The right call is to replace the mandatory account with a three-step guest checkout and a pre-filled mobile money number. Measured result: 5 to 10 % conversion gained per removed step, and payment time pulled under 40 seconds.
Why the mandatory account drives buyers away
Asking shoppers to create an account before paying adds 4 to 6 fields (email, password, confirmation) plus an email validation. On a 3G connection, every friction is paid in cash. A three-tap guest checkout — MoMo number → OTP → confirmation — removes most exit points.
| Funnel step | Mandatory account | 3-tap guest checkout |
|---|---|---|
| Fields to fill | 8 to 11 | 3 to 4 |
| Average time | 90 to 130 s | < 40 s |
| Abandonment points | 5 | 2 |
| Mobile conversion rate | 25 to 35 % | 40 to 55 % |
| Repeat purchase | yes | via recognised number |
Removing a single non-essential field (full address before payment, password creation) lifts conversion by 5 to 10 % based on 2026 observations.
Uganda and Gabon: the 2026 mobile money rails
The provider you pick drives fees and settlement. In Uganda, MTN MoMo and Airtel cover roughly 70 % of payments; in Gabon, Airtel Money and Moov Money dominate.
| Market | Key providers | Collection fees | Settlement | Checkout time target |
|---|---|---|---|---|
| Uganda (Kampala) | MTN MoMo, Airtel Money | 1.5 to 2 % | T+1 to T+2 | < 40 s |
| Gabon (Libreville) | Airtel Money, Moov Money | 1.5 to 2.5 % | T+0 to T+2 | < 40 s |
| Payment coverage | — | — | — | ~70 % (Uganda) |
These are 2026 order-of-magnitude figures: negotiate the collection rate as soon as monthly volume passes a few million UGX.

Mini case study
Meet Brian, who runs a sneaker shop in Kampala. He starts 400 carts a month, average basket UGX 100,000, but his checkout conversion is only 30 % (mandatory account). That's 120 sales = UGX 12,000,000/month.
Switching to a 3-tap guest checkout, conversion climbs to 45 % = 180 sales = UGX 18,000,000/month. Gross gain: +UGX 6,000,000/month. Even after MTN MoMo fees (2 % on the surplus, ~UGX 120,000), net gain tops UGX 5,800,000/month from a simple funnel change.
FAQ
How many fields does checkout really need? Three are often enough in 2026: mobile money number, OTP validation, confirmation. The delivery address can be collected after payment, cutting abandonment by 5 to 10 %.
Does guest checkout block loyalty? No: the MoMo number acts as the identifier. On repeat purchase it's recognised and pre-filled, giving the effect of an account without the sign-up friction.
What mobile money fees should I expect in Uganda and Gabon? Budget 1.5 to 2 % collection fees in Uganda (MTN/Airtel) and 1.5 to 2.5 % in Gabon (Airtel/Moov), with T+0 to T+2 settlement depending on the provider.
What checkout time should I aim for? Under 40 seconds from the "Pay" click to confirmation. Beyond a minute, abandonment spikes sharply on 3G.
Does the OTP slow payment too much? Not if the SMS arrives within a few seconds. It's one extra tap that secures the transaction and stays within the 40-second target.
