The verdict in three sentences
One mobile money transaction in 6 to 10 fails on the first try — that is not a bug, it is the reality of USSD and balances. A structured retry strategy (re-prompt, provider switch, deferred follow-up) recovers 30 to 45 % of these failures. Measured result: checkout conversion rises from 72 % to 84 %, without changing a single line of your catalogue.
Why it fails: the 2026 error codes
Not all failures are handled the same way. Some are recoverable with a simple re-prompt, others require another payment method.
| Code / cause | Share of failures | Recoverable? | Action |
|---|---|---|---|
| USSD timeout (customer too slow) | 30 to 40 % | Yes | Re-prompt after 60 s |
| Insufficient balance | 20 to 30 % | Partially | Offer another provider |
| PIN not entered / cancelled | 15 to 25 % | Yes | Immediate retry |
| Daily cap reached | 5 to 10 % | No (same day) | WhatsApp follow-up D+1 |
| Invalid number / account | 3 to 8 % | No | Correct the number |
| Temporary provider outage | 2 to 5 % | Yes | Provider switch |
The average resolution time for a recoverable failure ranges from 90 seconds to 4 minutes. Beyond 3 attempts, freeze the status as final failed to avoid annoying the customer.
The retry workflow that recovers sales
Three follow-up levels, from most automatic to most human.
| Step | Trigger | Delay | Recovery rate (order of magnitude) |
|---|---|---|---|
| Automatic re-prompt | Timeout / PIN cancelled | 60 s | 15 to 25 % |
| Provider switch | Insufficient balance / outage | Immediate | 10 to 15 % |
| Deferred WhatsApp follow-up | Cap / abandonment | 2 to 24 h | 8 to 12 % |
Final failed status | 3 failed attempts | — | Order cancelled |
Cumulatively, this workflow brings 30 to 45 % of failed baskets back to a successful payment. The key trick: never lock the customer to one provider — immediately offer M-Pesa if the card fails, and vice versa.

Mini case study
Ibrahim, a restaurateur in Accra, gets 500 online orders/month, average basket 9,000 FCFA-equivalent. Before retry: 15 % payment failure rate, i.e. 75 lost orders = 675,000 FCFA/month evaporated. After adding re-prompt + provider switch + WhatsApp follow-up, he recovers 40 % of those failures, i.e. 30 orders = 270,000 FCFA/month regained, for a development cost recouped in under three weeks.
FAQ
How many retry attempts are reasonable? Three maximum. Beyond that, recovery becomes marginal and the customer feels harassed. After 3 failures, set failed and a single deferred WhatsApp follow-up.
Can retry cause a double debit? No, if each attempt generates a new reference and you apply idempotency on the confirmed transaction_id. Only a successful payment validates the order.
Should I offer another provider automatically? Yes, it is the most profitable lever: on an insufficient balance, offering an alternative rail recovers 10 to 15 % of cases. Multi-provider = fewer final failures.
Is WhatsApp follow-up effective? On abandonments and daily caps, a D+1 follow-up with a payment link recovers 8 to 12 % of baskets. It is the cheapest recovery.
What is the real conversion impact? A full retry strategy typically lifts checkout conversion from 72 % to 84 % — roughly a sixth more payment revenue.
