The verdict in three sentences
In 2026, a subscription billed in mobile money fails frequently: insufficient balance, expired mandate, network. Without structured recovery, that involuntary churn of 12 to 25 % is money lost for nothing. A 4-retry ladder aligned with payday windows recovers 55 to 70 % of those failed payments.
Why recurring charges fail
Unlike a card, a mobile-money account fluctuates day to day. A customer's balance can be empty on the 20th and full on the 30th. A charge attempted at the wrong moment fails not because the customer refuses to pay, but because the timing is wrong.
The answer isn't to chase harder, but to chase smarter: at the right moment, on the right channel, with the right message. A retry realigned to the payday window (28th to 3rd) succeeds far more than a blunt attempt on the billing anniversary.
| Strategy | Estimated recovery | Cost / recovery |
|---|---|---|
| No dunning | 0 % | 0 |
| 1 fixed retry | 20 to 30 % | ~25 FCFA |
| Fixed 3-retry ladder | 40 to 50 % | ~75 FCFA |
| Smart 4-retry ladder | 55 to 70 % | ~120 FCFA |
| 4-retry + personal WhatsApp | 65 to 75 % | ~180 FCFA |
The cost of a reminder (SMS ~20-35 FCFA, WhatsApp near zero) is trivial against the value of a saved subscription. It's the best ROI in the entire retention chain.
The retry ladder that works
The ideal schedule combines automatic charge retries with human reminders, plus a grace period before suspension.
| Step | Timing | Channel | Message |
|---|---|---|---|
| Attempt 1 | D+0 (failure) | auto | silent |
| Reminder 1 | D+1 morning | SMS | gentle nudge |
| Attempt 2 | D+2 (payday window) | auto | silent |
| Reminder 2 | D+3 | payment link | |
| Attempt 3 | D+5 | auto | silent |
| Reminder 3 | D+7 | SMS + WhatsApp | final notice |
| Suspension | D+7 end of grace | easy reactivation |
Two golden rules: never suspend before the end of the grace period (3 to 7 days), and always offer a direct payment link so the customer can settle in one click. Friction kills recovery.

Without dunning, he lost those 162 subscribers → ~1.6M FCFA/month of MRR evaporated. With a smart 4-retry ladder recovering 62 %, he saves ~100 subscribers/month, that's ~990,000 FCFA of recovered MRR. Reminder cost: ~162 x 120 FCFA ≈ 19,000 FCFA. ROI above 50x.
FAQ
What's the involuntary churn rate in mobile money?
Between 12 and 25 % per month in 2026, mostly from insufficient balances and expired mandates — not a desire to cancel.
How much does a 4-retry ladder recover?
Between 55 and 70 % of failed payments. Adding a personal WhatsApp reminder can push it to 75 %.
When's the best time to retry a charge?
On the payday window, usually the 28th to the 3rd of the month, when mobile-money accounts are topped up. Timing matters more than frequency.
How much does a recovery cost?
Between 25 and 180 FCFA depending on strategy (SMS ~20-35 FCFA, WhatsApp near free). Negligible against the value of a saved subscription.
Should I suspend immediately after a failure?
No. Allow a 3 to 7 day grace period with reminders before any suspension. Suspending too early turns a delay into a permanent cancellation.
