The verdict in three sentences
Every extra screen in your payment funnel costs you 10 to 15% of buyers who quit. A one-click checkout — prefilled mobile-money number, calculated amount, and a USSD push sent straight to the phone — lifts mobile conversion from 1.8% to 3.2%. On a store with 1,000 visits/month and a 12,000 FCFA average basket, that is nearly 20,000 FCFA of incremental revenue recovered every month, with zero extra ad spend.
Why every step bleeds your conversion
The classic funnel — cart, address, account, operator choice, number entry, confirmation — stacks up friction. On mobile, over 3G, each field adds typing time and a chance to doubt. Here is the cumulative drop-off observed (2026 order of magnitude, Senegal / Côte d'Ivoire market) by number of steps.
| Number of steps | Cumulative drop-off | Final conversion | Sales / 1,000 visits |
|---|---|---|---|
| 1 step (one-click) | 8% | 3.2% | 32 |
| 2 steps | 18% | 2.7% | 27 |
| 3 steps | 32% | 2.3% | 23 |
| 4 steps | 46% | 2.0% | 20 |
| 5 steps | 58% | 1.8% | 18 |
Between a 5-step funnel and a one-click checkout, you go from 18 to 32 sales on the same traffic: +78% orders without touching marketing.
Incremental revenue, quantified
With a 12,000 FCFA average basket, the conversion gap translates directly into revenue. Here is the monthly projection by traffic tier.
| Visits / month | Revenue at 1.8% | Revenue at 3.2% | Incremental revenue |
|---|---|---|---|
| 1,000 | 216,000 FCFA | 384,000 FCFA | +168,000 FCFA |
| 3,000 | 648,000 FCFA | 1,152,000 FCFA | +504,000 FCFA |
| 5,000 | 1,080,000 FCFA | 1,920,000 FCFA | +840,000 FCFA |
| 10,000 | 2,160,000 FCFA | 3,840,000 FCFA | +1,680,000 FCFA |
One-click checkout is not a UX gadget: it is the cheapest lever to grow revenue, because it exploits traffic you already pay for.
Mini case study
Awa, who runs a cosmetics store in Dakar, gets 2,500 visits/month. With her old 4-step funnel she converted at 2.0%: 50 sales, or 600,000 FCFA in monthly revenue. After moving to a one-click checkout (prefilled Orange number, USSD push), she reaches 3.2%: 80 sales, or 960,000 FCFA. Net gain: +360,000 FCFA per month, for a one-off development fee. Payback is reached in under 3 weeks.

FAQ
How much conversion does a one-click checkout really add?
On average you move from 1.8% to 3.2% on mobile, a relative gain of about +78% in orders at constant traffic. The size depends on how many steps you remove.
Does the USSD push work with Wave and Orange Money?
Yes. Wave sends an instant payment link, and Orange Money triggers a USSD push or confirmation code. Either way, the buyer validates in under 15 seconds without leaving your store.
Should I force customers to create an account?
No, it backfires: forcing account creation drops conversion by 25 to 35%. The mobile-money number works as an identifier for 90% of cases.
What does it cost to set up?
A one-click checkout module added to an existing store typically costs between 250,000 and 600,000 FCFA depending on complexity, often paid back within a month of extra sales.
Does it work on slow 3G too?
Yes, and that is one of the main benefits: fewer fields and page reloads reduce failures on unstable networks, where every extra screen loses buyers.
