The verdict in three sentences
Automatic card debit barely exists in West Africa: fewer than 10 % of your base will have a card that supports recurring charges. For a mobile money subscription you have three architectures — manual link reminders, a PSP token (debit mandate kept by the provider), or scheduled USSD — and their retention ranges from 60 % to 85 %. The right choice depends on volume: under 100 subscribers, link reminders suffice; beyond that, the PSP token quickly pays back its integration cost.
The three architectures compared
There is no universal "mobile money SEPA" in 2026. Here is how each model behaves on a Senegalese subscriber base, as a 2026 order of magnitude.
| Architecture | Monthly retention | Fee per charge | Settlement delay | Operational effort |
|---|---|---|---|---|
| Manual link reminder (WhatsApp) | 60 % | 1.0–1.5 % | 1–3 days | High (sent by hand) |
| Automated link (J+0/J+3 sequence) | 72 % | 1.0–1.5 % | 1–2 days | Medium |
| PSP token / debit mandate | 85 % | 1.5–2.0 % | Instant | Low after setup |
| Scheduled USSD reminder | 68 % | 1.0–1.5 % | 1–2 days | Medium |
| Bank card (Stripe) | 88 % | 2.9 % + 100 FCFA | Instant | Low but base <10 % |
The PSP token (offered by some aggregators and by Wave Business on application) keeps a debit authorization: the customer approves once, then each charge is pulled automatically. It is the only option approaching "card" retention while staying 100 % mobile money.
Pricing models and revenue impact
Retention weighs more than fees. On two typical tiers, here is the effect of 60 % vs 85 % retention on 100 subscribers.
| Tier | Monthly price | Gross/month 100 subs | Net after 60 % churn | Net after 85 % churn |
|---|---|---|---|---|
| Starter | 9,900 FCFA | 990,000 FCFA | 594,000 FCFA | 841,500 FCFA |
| Pro | 24,900 FCFA | 2,490,000 FCFA | 1,494,000 FCFA | 2,116,500 FCFA |
| PSP fee (2 %) Pro | — | −49,800 FCFA | — | −42,330 FCFA |
| Annual gap Pro | — | — | — | +7.47M FCFA/yr |
Moving from 60 % to 85 % retention on the Pro tier recovers over 7 million FCFA of annual revenue, versus extra PSP fees of a few tens of thousands of FCFA per month.

Fatou builds management software for pharmacies in Dakar: 120 subscribers at 24,900 FCFA/month. With manual reminders her retention capped at 60 %, i.e. 1,792,800 FCFA collected. After moving to a PSP token (85 % retention) she collects 2,539,800 FCFA/month, minus 2 % fees (50,796 FCFA). Net gain: +696,204 FCFA per month, for a one-off integration cost of around 350,000 FCFA — paid back in under three weeks.
FAQ
Can you really auto-debit Wave or Orange Money?
Not self-service like a card, but via a debit mandate (token) granted by the PSP on a business application. The customer authorizes once; later charges are pulled with no action on their part, with retention near 85 %.
What is the real cost per charge?
Expect 1.0–1.5 % on standard mobile money and 1.5–2.0 % with a PSP token, versus 2.9 % + 100 FCFA for a Stripe card. On 24,900 FCFA that is 250–500 FCFA per collection.
What about the 15 % who don't renew?
A J+1, J+3, J+7 reminder sequence recovers 30–65 % of involuntary failures. After three reminders with no reply, suspend access rather than piling up lost charges.
Should I keep Stripe for the diaspora?
Yes: for customers outside the FCFA zone a card stays simpler. A unified module lets each subscriber pick Wave, Orange Money or card by location.
