The verdict in three sentences
Unlike cards, mobile money has no native auto-debit everywhere: you need a pre-approved mandate (MTN, Orange) or a token. In 2026, recurring collection succeeds around 82%, leaving involuntary churn of ~8% that only a structured retry recovers. For a SaaS or subscription, the mandate + retry logic matters as much as the product itself.
Card token vs mobile money mandate
Two mechanics to automate a subscription, with different constraints.
| Criterion | Card token | Mobile money mandate |
|---|---|---|
| Debit without customer action | Yes | Yes, after signed mandate |
| Recurring success rate | 85 - 92% | ~ 82% |
| Main failure cause | Expired card | Insufficient balance |
| Setup | PCI tokenization | USSD/app mandate |
| Cost per transaction | 1.5 - 3.5% | 1 - 2% |
| Diaspora reach | Excellent | Weak |
The mobile money mandate wins on fees and the local market; the card token wins on diaspora and reliability.
The subscription flow and the retry
A failed collection is not a final loss: the balance often reloads within 24-72h. Hence a retry cadence.
| Step | Action | Timing |
|---|---|---|
| D0 | Collection attempt | Due date |
| D+1 | 1st auto retry + SMS | 24h after failure |
| D+3 | 2nd attempt + app notification | 72h after failure |
| D+5 | Human retry / WhatsApp | 120h |
| D+7 | Soft service suspension | End of grace |
A D+1/D+3 cadence typically recovers 40-55% of failures, bringing involuntary churn from 8% down toward 3-4%.
Mini case study
A Dakar SaaS vendor has 1,000 subscribers at 9,900 FCFA/month (9,900,000 FCFA theoretical MRR). At 82% success, 180 collections fail, i.e. 1,782,000 FCFA at risk. With a D+1/D+3 retry recovering 50%, it saves 90 subscriptions (891,000 FCFA/month) — over 10 million FCFA a year.

FAQ
Can you debit a mobile money customer without their action?
Yes, but only after they validate a pre-approved mandate (via USSD or app). Without that mandate, each payment needs manual confirmation.
Why does mobile money recurring fail more than cards?
The number-one cause is insufficient balance on the due date, very common on wallets topped up as you go. Hence the importance of retries.
Is tokenization needed for a card subscription?
Yes: storing a raw number is banned by PCI-DSS. The token lets you replay the payment without keeping the card.
What is a good involuntary churn rate?
Under 4% in 2026 is considered healthy. Without retries, it climbs toward 8% and silently erodes MRR.
Should I offer card AND mobile money for subscriptions?
Yes: mobile money covers local, the tokenized card covers diaspora. The combination maximizes retention.
