The verdict in three sentences
In Lagos, 55% of carts are abandoned at checkout and every superfluous field costs roughly 7% of conversion on mobile. The two highest-impact levers are guest checkout (+11 points) and one-tap mobile money (+9 points). Combining all seven optimizations lifts a baseline checkout from 42% to over 60%, without changing the product or the price.
The 7 levers, ranked by gain over effort
Not all optimizations are equal. Guest checkout takes a day to code and returns 11 points; a full funnel rebuild takes weeks for a marginal gain. Here is the quantified priority order for Lagos.
| Lever | Conversion gain | Effort | Priority |
|---|---|---|---|
| Guest checkout (no account) | +11 points | Low | 1 |
| Mobile money one-tap | +9 points | Medium | 2 |
| Address autocomplete | +5 points | Medium | 3 |
| Progress bar | +4 points | Low | 4 |
| Delivery fees shown early | -6 pts abandonment | Low | 5 |
| Load < 2 s on 3G | Retains the impatient | Medium | 6 |
| Fields cut to the minimum | +7% per field removed | Low | 7 |
Why mobile changes everything in Lagos
Most buyers arrive on 3G with a 5-inch screen and a slow keyboard. Every field to fill, every second of loading, every redirect to a payment page is a chance to abandon. The goal: cut the number of taps between "add to cart" and "payment confirmed" to under ten.
| Checkout metric | 2026 value (estimate) |
|---|---|
| Baseline checkout conversion | 42% |
| Checkout abandonment rate | 55% |
| Average basket | 24,000 FCFA |
| Cost per unnecessary field | -7% conversion |
| Load target on 3G | < 2 s |
| Target conversion after optimizations | > 60% |
Mini case study
Nadege sells cosmetics in Lagos with 500 checkout sessions a month and 42% conversion, i.e. 210 orders at 24,000 FCFA = 5,040,000 FCFA. She enables guest checkout (+11 pts) and one-tap mobile money (+9 pts), lifting conversion to 62%. She now reaches 310 orders, i.e. 7,440,000 FCFA, a gain of 2,400,000 FCFA a month for two optimizations coded in under a week.

Does guest checkout really win 11 points?
Yes, forcing account creation before payment is one of the top abandonment causes. The account can be offered after payment, without blocking the sale: the observed gain is around 11 conversion points.
Why show delivery fees early?
A delivery fee discovered at the last step triggers a surprise abandonment. Showing it from the cart cuts abandonment by about 6 points, even if the amount is identical.
Is one-tap mobile money hard to integrate?
Medium effort, but well worth it at +9 points of conversion. The goal is to avoid re-entering the number and the multiple redirects that lose the buyer.
How much does each superfluous field cost?
About 7% of conversion per non-essential field on mobile. Ask only what's essential for delivery and payment; the rest can wait.
Is load time on 3G really critical?
Yes, beyond 2 seconds a large share of impatient buyers leaves the page. On the Nigerian market, optimizing for 3G is not optional.
