Involuntary churn

A subscriber signs up in April on a card that expires the following March. Eleven months later the annual renewal posts, the charge declines, and the subscription ends without the subscriber deciding anything. Voluntary churn is a decision someone made about the product. Involuntary churn is a payment instrument that stopped working, and the two rarely respond to the same fix.

Expired cards are the common case, but the category also covers insufficient funds, a bank declining a recurring charge as suspected fraud, and a card reissued after a breach with a number the store never received. On store-managed subscriptions the retry schedule belongs to Apple, Google, Roku, or Amazon rather than to the publisher, so the failure can play out entirely between the store and the subscriber’s bank. The app sees a cancellation at the end of it. Unless it is reading subscription state, it has no way to tell that outcome apart from someone who chose to leave.

Separating the two numbers is the first move, because each one calls for a different response. A subscriber who cancelled deliberately needs a reason to come back. A subscriber whose card failed needs to know it failed, in the app, while access is still live. Recovering that second group is the job of dunning, and the recovery sequence is a branch in the subscriber journey rather than a billing setting, which is why it gets built in Flows alongside everything else the subscriber sees.
