The verdict in three sentences
Between 60 and 70 % of mobile money baskets are abandoned, not for lack of intent but because of a broken technical flow: slow USSD redirect, failing OTP, no status feedback. A checkout with deep-link and status polling recovers up to +18 points of conversion. Each abandoned basket wastes ~2,500 FCFA of acquisition cost.
Where the flow breaks
Mobile money payment chains several fragile steps. Audit each one with a stopwatch and a failure rate.
| Step | Common problem | Conversion impact |
|---|---|---|
| Redirect to app | Slow (25 s USSD) | -15 pts |
| OTP entry | 12 % failure | -8 pts |
| Return to merchant | Missing / manual | -12 pts |
| Status confirmation | No polling | Doubt, abandon |
| Retry | Starts from zero | Frustration |
The customer doesn't know whether the payment succeeded: they close the tab, retry, or pay twice. That is where the points bleed out.
Before / after optimisation
Here is the measured effect of an optimised flow (direct deep-link to the app, status polling, clear confirmation screen). 2026 order-of-magnitude figures.
| Metric | Before | After |
|---|---|---|
| Abandonment rate | 68 % | 50 % |
| Redirect time | 25 s | 6 s |
| OTP failure | 12 % | 4 % |
| Checkout conversion | 32 % | 50 % |
| Lost acquisition cost/basket | 2,500 FCFA | — |

The deep-link opens Wave or Orange Money directly at the right amount; polling queries the API every 2-3 seconds and shows "payment confirmed" without the customer refreshing.
Mini case study
Moussa sells sneakers online in Accra. Traffic: 1,000 checkouts/month, conversion 32 %, basket 25,000 FCFA. So he books 320 sales (8,000,000 FCFA). After reworking the flow (deep-link + polling), conversion rises to 50 %: 500 sales (12,500,000 FCFA). Gain: 180 sales, +4,500,000 FCFA/month. The acquisition cost previously wasted on 680 abandonments (~1,700,000 FCFA) is finally paying off.
FAQ
Does the deep-link work on all phones? On smartphones with the app installed, yes, directly. For others, plan a QR code or USSD fallback, with the same status polling behind it.
Why does polling change everything? It removes uncertainty: the merchant detects confirmation server-side and shows the real state, instead of letting the customer guess whether they paid.
How do I reduce OTP failures? Pre-filling the amount, avoiding overly short expiry, and allowing a retry without starting over cut failures from 12 % to ~4 %.
What realistic gain? On a degraded flow, +15 to +18 points of conversion are achievable. The return on investment shows within weeks for an active e-commerce store.
