The verdict in three sentences
Unlike cards, mobile money has no native auto-debit: a subscription relies either on a standing-order mandate or a scheduled prompt the customer must approve every month. As a result, involuntary churn (renewal failures, not intent to leave) is the silent killer of recurring revenue. A well-designed dunning sequence recovers 30 to 45% of these failed renewals.
Mandate vs prompt: two opposite models
In Togo, Moov and Orange Money offer no true auto-debit, so subscriptions there are 100% prompt-based. Where a mandate exists (M-Pesa style), it stays capped.
| Model | How it works | Renewal failure rate | Typical zone |
|---|---|---|---|
| Mandate / standing order | capped auto-debit | 8 to 15% | M-Pesa Kenya |
| Monthly STK / USSD prompt | customer approves each month | 15 to 25% | Nairobi push-only |
| WhatsApp prompt + link | reminder + payment link | 12 to 20% | Lome, Moov/OM |
Without auto-debit, every renewal is a micro-conversion to win: forgetfulness, insufficient balance or an invalid PIN fail one to two subscribers in five.
The cost of involuntary churn
| Metric | Assumption | Annual impact per subscriber |
|---|---|---|
| Monthly subscription | 3,900 FCFA | 46,800 FCFA if 12 months |
| Renewal failure rate | 20% | -2.4 months lost |
| Lost revenue per subscriber | 20% x 46,800 | -9,360 FCFA/year |
| Recovery via dunning (35%) | +0.84 month | +3,276 FCFA/year |
Across 500 subscribers, an untreated 20% involuntary churn is about 4,680,000 FCFA/year lost; a dunning sequence recovers a large share.
The dunning sequence that works
The key is rhythm: not too early, not too late. A three-step sequence (day 0, +2, +5) recovers 30 to 45% of failures.
| Step | Timing | Channel | Message |
|---|---|---|---|
| Day 0 | renewal failure | STK push / prompt | "Confirm your subscription" |
| Day +2 | reminder | WhatsApp + link | polite reminder + benefit |
| Day +5 | last chance | WhatsApp + SMS | before service suspension |

Mini case study
In Nairobi, a beauty-box service at 3,900 FCFA/month has 500 subscribers. Push-only without dunning, 20% of renewals fail each month, i.e. 100 unbilled subscribers, ~390,000 FCFA of MRR lost monthly. Adding a Day 0 / +2 / +5 sequence that recovers 40%, the business recovers 40 subscribers, i.e. +156,000 FCFA of MRR per month, or ~1,872,000 FCFA/year, for the sole cost of automating the reminders.
FAQ
Why can't I just auto-debit every month?
Because most West African mobile money operators, including Moov and Orange Money in Togo, offer no native auto-debit like cards. The customer must approve a prompt, which creates involuntary churn.
What exactly is involuntary churn?
It is subscribers who leave not by choice but by technical renewal failure (insufficient balance, missed prompt, expired PIN). It often accounts for 15 to 25% of renewals in push-only setups.
What is the right reminder rhythm?
A three-step sequence, day 0, +2 and +5, recovers 30 to 45% of failures. Too many messages annoy, too few let the subscriber forget; three well-spaced ones are the sweet spot.
Does the M-Pesa mandate solve everything?
It cuts failures to 8 to 15% but stays capped in amount and does not cover all operators. For Moov and OM Togo, you still need a prompt and dunning strategy.
