involuntary churn
Also called: passive churn, delinquent churn, failed payment churn, payment churn
Customers lost because their payment failed and was never recovered (an expired, blocked or empty card), not because they chose to cancel.
Involuntary churn is the part of churn that happens without anyone deciding to leave: a card expires or is replaced, a bank blocks a payment, an account runs out of money, and the subscription quietly ends. The customer may still be using the product and may even be happy with it; they just stopped paying.
It deserves its own line in the report because it behaves differently from voluntary churn. Voluntary churn is about value (the product, the price, the customer's situation) and takes product work to fix. Involuntary churn is about payment mechanics and can often be cut sharply in weeks with retries, clear messages, card-expiry reminders and alternatives such as yearly plans or invoices. In many small subscription businesses it is a large share of all churn, and the cheapest to reduce.
To measure it, tag every lost customer with the reason: cancelled, or payment failed and not recovered. Report involuntary churn = customers lost to failed payments ÷ customers at the start of the period, next to voluntary churn. If the involuntary share is high, fix dunning before you spend on anything else.
Example
In October GarageDesk starts with 58 shops and loses 3: one shop's card expired and nobody noticed, one never loaded its client list, and one moved to a cheap general CRM.
Involuntary churn = 1 / 58 ≈ 1.7% of the month's 3 / 58 ≈ 5.2%. Looking further back, 4 of the 11 shops lost since the March launch were failed payments, more than a third of all churn. Those are the cheapest departures to prevent: a card-expiry notice, a payment link in Viber and a call.
Common mistakes
- Lumping it in with cancellations. Tag each lost customer with a reason, or you'll try to fix the wrong problem.
- Assuming failed payments fix themselves. Without retries and messages, most of them turn into churn.
- Only one payment method. Yearly plans and invoices reduce card failures for customers who prefer them.
- Deleting data on failure. Pause instead, so returning is easy.
