The verdict in three sentences
Mobile money was built for one-off pushes, not recurring billing. Without a mandate, manual monthly re-collection causes 25-40 % churn, versus 8-15 % with a recurring mandate where available. A 3-5 day dunning retry recovers 20-35 % of failed renewals, and an SMS pre-charge reminder adds 10-18 points of success.
Manual re-collection vs mandate: the real cost of churn
Billing a subscription by mobile money without an automatic mechanism means asking every customer to re-pay manually each month. Many forget, and churn explodes.
| Method | Monthly involuntary churn | Customer effort | Availability |
|---|---|---|---|
| Manual re-push | 25 to 40 % | High (re-pay) | Everywhere |
| Mandate / direct debit | 8 to 15 % | None (auto) | Operator-dependent |
| Tokenized card (Paystack) | 10 to 18 % | None | International |
The recurring mandate (approved once by the customer with MTN or Airtel where it exists) radically changes retention: involuntary churn, the kind caused by a simple missed payment, drops by more than half.
Dunning and reminders: recovering failures
Even with a mandate, some renewals fail (insufficient balance, cap). A structured retry strategy recovers a large share of those losses.
| Lever | Effect (2026 order of magnitude) |
|---|---|
| SMS reminder before charge | +10 to +18 points of success |
| Dunning retry over 3-5 days | Recovers 20 to 35 % of failures |
| Tokenized card fallback 1.5 % | Alternative if momo fails |
| LTV per retained subscriber | 3x to 6x |
The SMS reminder sent the day before the charge prompts the customer to ensure a sufficient balance: simple, cheap, very effective. Dunning (automatic retries staggered over 3-5 days) then recovers a share of residual failures.
Mini case study
Chidi runs an online course app in Lagos with 1,000 subscribers at NGN equivalent 5,000/month, on manual re-push. His involuntary churn is 32 %, meaning 320 subscribers lost each month to non-repayment.
He enables a recurring mandate plus an SMS reminder and a 4-day dunning cycle. Involuntary churn drops to 12 %, i.e. 120 losses monthly instead of 320: 200 subscribers preserved each month, saving 1,000,000 in recurring revenue monthly. With LTV multiplied 3 to 6x on retained subscribers, the impact on portfolio value is major.

FAQ
Why does mobile money handle subscriptions poorly?
It was built for one-off transactions where the customer validates each payment. Without a mandate, you must re-prompt the customer every month, generating 25-40 % involuntary churn.
What is a recurring mandate?
It is a one-time authorization the customer gives the operator (MTN, Airtel) to auto-debit the subscription. It cuts involuntary churn to 8-15 % where available.
Is dunning worth it?
Yes. An automatic retry staggered over 3-5 days recovers 20 to 35 % of failed renewals, often caused by a temporarily insufficient balance.
Do I need a card fallback?
A tokenized card fallback (via Paystack, ~1.5 %) offers an alternative when mobile money fails, useful especially for diaspora and international customers.
Is the SMS reminder really useful?
Yes. A reminder sent before the charge adds 10 to 18 points of success by prompting the customer to fund their account.
