Involuntary vs. voluntary churn
The difference between churn from a failed payment and churn from an active decision to cancel — and which WallaB features address each.
Churn is the loss of a subscriber, and it comes in two kinds. Involuntary churn is a subscription lost to a failed payment — an expired or declined card — where the customer never actually chose to leave. Voluntary churn is a subscriber making an active decision to cancel. The difference matters because each kind is prevented in a completely different way.
Which WallaB features address each
Involuntary churn is fought before and after a charge fails:
- Dunning retries a failed payment on a schedule and emails the shopper to fix their card — see What is dunning?.
- Card-expiry warnings catch a soon-to-expire card before it ever declines, and a backup card can be charged when the primary fails.
Voluntary churn is fought at, and after, the decision to cancel:
- The cancel-save flow offers a pause, skip, swap, or discount when a shopper tries to cancel — see What is a cancel-save flow?.
- Win-backs reach out to already-cancelled subscribers with a guardrailed offer to come back — see Win-back & campaigns.
Why keep them separate
Counting the two together hides what to fix. A rise in involuntary churn points at billing and card health; a rise in voluntary churn points at price, product, or experience. WallaB.AI keeps the two distinct so the right lever is obvious.
