The verdict in three sentences
In Accra, 82% of e-commerce traffic is mobile and much of it runs on 3G: your checkout must be built for slowness and small data. In 2026, cutting a checkout from 5 to 2 fields raises conversion by 34% and a single page loads in 2.1s versus 6.8s for a multi-page flow. Each extra second of latency costs 7% of conversion: speed is not a detail, it is revenue.
Multi-page vs single-page checkout
The classic 4-screen flow (cart, address, shipping, payment) multiplies 3G loads and chances to drop off. A single page with pre-filled mobile-money payment concentrates everything.
| Criterion | Multi-page checkout | Single-page pre-filled checkout |
|---|---|---|
| Load time (3G) | 6.8s | 2.1s |
| Fields to fill | 5+ | 2 |
| Mobile conversion | Base | +34% |
| Account required | Common | Guest by default (+21%) |
| Payment | Multiple redirects | One-click mobile money |
| Page weight | ~1.8 MB | ~480 KB |
3G performance checklist
3G speed is won as much on checkout structure as on tech. Here are the high-impact levers for 2026.
| Lever | Measured effect | Priority |
|---|---|---|
| Go from 5 to 2 fields | +34% conversion | High |
| Guest checkout by default | +21% vs required account | High |
| Pre-filled mobile-money payment | -1 step, fewer errors | High |
| Compressed WebP/AVIF images | -60% weight | Medium |
| Pre-formatted phone number | Less typing | Medium |
| Remove 1s of latency | +7% conversion | High |
| No needless payment redirect | Fewer drop-offs | High |
Golden rule: ask only what is essential to the order. Name, phone and mobile-money choice are enough; email and account creation can come after purchase.

FAQ
How many fields max in a 3G checkout? Two, ideally. Going from 5 to 2 fields raises conversion by 34%; name, phone and payment choice are enough to place the order.
Should I force account creation? No. Guest checkout converts 21% more than a required account. Offer account creation after payment, once the sale is secured.
Is a single page really faster? Yes: about 2.1s load versus 6.8s for a multi-page flow on 3G, because you avoid intermediate reloads. It is the number-one mobile conversion factor in Accra.
What is the real impact of latency? Each extra second of latency loses about 7% of conversion. On an already slow checkout, shaving 2 seconds can beat an ad campaign.
How do I lighten the page without losing quality? Compress images to WebP/AVIF (up to -60% weight), drop useless scripts and pre-fill everything you can. Going from 1.8 MB to under 500 KB is common.
