The verdict in three sentences
On a mobile money subscription, the top failure cause is not refusal but insufficient balance (55% of cases), which drives 11 to 16% involuntary churn. A dunning strategy — an automatic reminder sequence with retries, SMS, USSD and a grace period — recovers 38% of failed payments. Well tuned, it adds +7 points of net retention without touching your product.
Anatomy of a recurring payment failure
Understanding why a debit fails lets you recover it. On mobile money, failure is rarely final: it is often a timing issue with wallet top-up.
| Failure cause | 2026 share | Recoverable? |
|---|---|---|
| Insufficient balance | 55% | Yes, very much |
| Wallet not topped up in time | 20% | Yes |
| Mandate cap reached | 10% | Yes, adjust the cap |
| Mandate revoked | 8% | No (manual reactivation) |
| Operator technical error | 7% | Yes, immediate retry |
Over 85% of failures are therefore recoverable through a well-timed reminder sequence — provided you don't cut access on the first failure.
The dunning sequence that recovers
Smart dunning doesn't bombard the customer: it retries at the right times, on the right channels, keeping access during a grace period.
| Step | Timing | Action | Cumulative recovery |
|---|---|---|---|
| Initial failure | J0 | Soft notice + access kept | — |
| Retry 1 | J+1 | Token debit + SMS | 18% |
| Retry 2 | J+3 | Token debit + USSD reminder | 30% |
| Retry 3 | J+7 | Token debit + human reminder | 38% |
| End of grace period | J+5 to J+7 | Progressive restriction | Limits churn |
The 5-day grace period is crucial: cutting access immediately turns a mere top-up delay into a cancellation. By keeping access during retries, you recover up to 38% of failed payments and gain +7 points of net retention.
Mini case study
Chidi runs a subscription platform in Lagos: 2,000 subscribers at the equivalent of 12,000 FCFA/month. Without dunning, 14% involuntary churn loses him 280 subscribers/month, i.e. 3,360,000 FCFA of MRR gone each month. Deploying the retry J+1/J+3/J+7 + grace period sequence, he recovers 38% of failures, i.e. about 106 subscribers saved/month = 1,272,000 FCFA of MRR preserved monthly. The SMS/USSD cost of the sequence runs about 80,000 FCFA/month: the return exceeds 15x the spend.

FAQ
What is the top failure cause on mobile money?
Insufficient balance, responsible for 55% of failures. That is the best possible news: these failures are highly recoverable via a retry after top-up.
How much involuntary churn does a subscription suffer?
Between 11 and 16% without a reminder strategy. Smart dunning recovers 38% of it, representing several million FCFA of MRR on a base of a few thousand subscribers.
How often should you retry without annoying?
A retry at J+1, J+3 then J+7, combining SMS and USSD reminders. Beyond that, returns collapse and irritation risk rises.
What is the grace period for?
To keep access for 5 days after failure, giving the customer time to top up. Cutting immediately turns a harmless delay into a permanent cancellation.
