The verdict in three sentences
Mobile money has no native card-style auto-debit, so any subscription loses 20–40% of MRR to silent failures unless it builds a mandate + dunning system. A pre-authorised mandate (token) cuts friction, but it's mainly the dunning sequence (D+0/D+2/D+5) that recovers 35–55% of failed payments. Subscription retention is decided less by the product than by your recovery engine.
Mandate vs push-to-pay: two models
Two approaches coexist. The mandate/token stores a recurring authorisation (MTN MoMo Ghana collection API, emerging Wave/OM mandates) and attempts the debit automatically. Push-to-pay sends a payment request each cycle that the customer approves on their phone. The first maximises success rate, the second is simpler to set up and reassures on consent.
| Model | Debit | Customer friction | 1st-attempt success | Merchant fee | Best for |
|---|---|---|---|---|---|
| Recurring mandate/token | Automatic | Low | ~75–85% | ~1–1.5% | SaaS, monthly box |
| Scheduled push-to-pay | Semi-manual | Medium | ~55–65% | ~1–1.5% | Services, associations |
| MTN MoMo recurring API (Ghana) | Automatic | Low | ~70–80% | ~1.5% | Cross-border subscriptions |
| WhatsApp reminder only | Manual | High | ~40–50% | 0 (excl. sending) | Small volumes |

The dunning sequence that recovers cash
A failed payment isn't a cancellation: it's an insufficient balance, a limit hit or an expired token. With a grace period of 3–7 days and a paced sequence, most of them recover.
| Failure reason | Action | Timing | Recovery rate |
|---|---|---|---|
| Insufficient balance | Auto-retry + WhatsApp reminder | D+0 | ~60% |
| Balance still low | 2nd retry + push-to-pay link | D+2 | ~25% |
| Token/mandate expired | Re-consent request | D+3 | ~40% |
| Mobile money limit hit | Message + split or wait for reset | D+2 | ~30% |
| Silence after D+5 | Final reminder + soft suspension | D+5 | ~15% |

Kwame runs a SaaS service in Accra at 24,900 FCFA/month (≈GHS equivalent) with 300 subscribers, i.e. 7,470,000 FCFA of MRR. Without dunning he suffers 20% involuntary failures/month, or 1,494,000 FCFA lost. By deploying a D+0/D+2/D+5 WhatsApp sequence that recovers 45% of those failures, he saves 672,300 FCFA per month — over 8,000,000 FCFA a year — at near-zero recovery cost. The same logic on a monthly box at 9,900 FCFA protects recurring cash flow.
FAQ
How much do you lose without dunning? A mobile-money subscription suffers 15–30% involuntary churn per month in silent failures; on 5,000,000 FCFA of MRR that's 750,000–1,500,000 FCFA evaporating.
What does a dunning sequence recover? A paced WhatsApp sequence at D+0/D+2/D+5 recovers 35–55% of failed payments, with the first attempt alone capturing about 60% of insufficient-balance cases.
How many attempts should I schedule? Three to four: the 1st attempt succeeds in ~60% of cases, the 2nd adds ~25%, and beyond that returns drop sharply — no need to nag.
What fees apply on recurring? Budget ~1% on Wave merchant and ~1.5% on Orange Money in 2026 (or MTN MoMo equivalents); these are dwarfed by the MRR you recover.
Do I need a grace period? Yes: 3–7 days of maintained access during dunning avoids cancelling a customer who was simply about to top up their wallet.
