The verdict in three sentences
80% of West African e-commerce traffic comes via smartphone, often on 3G, so every checkout friction costs real sales. A minimal flow — no mandatory account, phone and address autofill, 1-tap mobile money payment — lifts completion: +7% per removed field and +25% with guest checkout. Below 3G, a load time under 2.5 seconds becomes the red line you never cross.
The minimal 3-step flow
The goal is to go from cart to confirmation in three light screens, never forcing account creation.
| Step | What to keep | What to remove |
|---|---|---|
| 1. Cart | Clear total + delivery | Promo codes up front |
| 2. Details | Name, phone, address (autofill) | Mandatory account creation |
| 3. Payment | Mobile money 1 tap | Multiple redirects |
| Confirmation | Light page + SMS | Pop-ups, heavy upsells |
Fewer screens, fewer fields, fewer redirects: every removal translates into conversion points.
The measured impact of each optimization
These levers are measurable and stackable. Here is a 2026 order of magnitude for a mobile checkout in West Africa.
| Optimization | Estimated completion gain |
|---|---|
| Guest checkout (no account) | +25% |
| Each removed form field | +7% |
| Phone/address autofill | +12% |
| 1-tap mobile money payment | +18% |
| Load < 2.5s (vs 5s) | +14% |
| Visible progress bar | +6% |
A checkout stacking these gains can double its completion rate versus a heavy generic flow.
Mini case study
Ibrahim, a restaurateur running a takeaway store, gets 2,000 add-to-carts/month but converts only 48%, i.e. 960 orders. He removes the mandatory account (+25%), adds autofill (+12%) and 1-tap mobile money payment (+18%). Even cautiously applying half of these gains, completion rises to ~62%, i.e. 1,240 orders/month. At an 8,000 FCFA basket, that is 2,240,000 FCFA of extra sales per month.

FAQ
Should I force account creation?
No. Guest checkout raises completion by about +25%; offer account creation as an option, after the order, not before.
What load time should I target?
Under 2.5 seconds on mobile; below 3G, a flow loading in 5 seconds loses roughly 14% completion versus a fast one.
How many form fields?
The strict minimum: name, phone, address. Each removed field adds on average +7% completion, so ban any non-essential field.
Does 1-tap mobile money payment really matter?
Yes: a 1-tap MoMo or mobile money payment, with no multiple redirects, improves completion by around +18% versus a complex payment flow.
How do I measure my drop-off?
Track the cart → confirmation completion rate; on mobile in West Africa, aiming for 60%+ is a good target, versus 40-48% for an unoptimized flow.
