The verdict in three sentences
The SaaS model rests on one metric: does the payment renew itself next month? In Nairobi in 2026, 13 % of mobile money charges fail on the first attempt, but automatic dunning recovers 9 points. With an M-Pesa mandate, an ARPU of 9,900 FCFA and churn held at 7 %, an African vendor can build solid recurring revenue — provided dunning is industrialized.
Why renewal is the real challenge
In the West, the card charges silently. In this region, mobile money often needs a customer validation, and wallet balances fluctuate. The result: 13 % first-pass failures. Without dunning, those 13 % become pure churn. With automatic dunning (retry at D+1, D+3, D+5 plus a notification), most of it is recovered.
The direct-debit mandate is a game changer: the customer authorizes once, then later attempts only ask for a light confirmation. Combining mandate, dunning and notification turns suffered churn into chosen churn.
| Metric | Without dunning (2026) | With auto dunning (2026) |
|---|---|---|
| 1st-charge failure rate | 13 % | 13 % |
| Recovery after dunning | 0 | +9 pts |
| Net final failure | 13 % | ~4 % |
| Monthly churn | 12 % | 7 % |
| ARPU | 9,900 FCFA | 9,900 FCFA |
| Mobile money fees | 1.5 % | 1.5 % |
Recurring channels and their mechanics
Mandates don't exist the same way everywhere. The table compares M-Pesa Kenya (via the Daraja API) with other wallets — 2026 order of magnitude.
| Channel | Recurring mechanism | 2026 fees | Payout delay |
|---|---|---|---|
| M-Pesa (Kenya, Daraja API) | STK Push / mandate | ~1 % to 1.5 % | T+1 |
| Other wallets | mandate + dunning | 1.5 % | T+1 to T+2 |
| Stripe card (international) | automatic charge | 2.9 % + fixed | T+2 to T+5 |
Mini case study
Kodjo runs a management SaaS, 500 subscribers at 9,900 FCFA, i.e. 4,950,000 FCFA theoretical MRR. Without dunning, at 13 % failure, he collects only 435 subscribers = 4,306,500 FCFA. Turning on automatic dunning, net failure falls to 4 %, i.e. 480 subscribers = 4,752,000 FCFA, i.e. +445,500 FCFA/month recovered. Over the year that's +5,346,000 FCFA. After M-Pesa fees (1.5 %), the net gain stays large — the dunning module pays for itself in the first month.

FAQ
Why do 13 % of charges fail?
Insufficient balance at charge time, unconfirmed customer validation, or a network drop. Automatic dunning at D+1, D+3 and D+5 recovers most of these cases.
Must the customer validate every month?
With an M-Pesa mandate, the initial validation authorizes the charges; later months only need a light confirmation, sharply reducing friction.
How does M-Pesa work in Kenya?
Via the Daraja API, you trigger an STK Push or a mandate for recurring billing, at fees around 1 to 1.5 % and a T+1 payout. The dunning principle is identical.
What churn should I target?
A well-run African SaaS targets monthly churn around 7 %. Automatic dunning is the fastest lever to move from 12 % to 7 %.
How much does the recurring billing module cost?
It's built into the SaaS development; the extra cost is quickly absorbed, since recovering 9 failure points on a multi-million FCFA MRR far exceeds the investment.
