Churn Buster
Failed payment recovery and cancel flow optimization for subscription brands
Churnbuster provides dunning and cancel flows for subscription brands.
Churn Buster recovers subscription revenue two ways: retrying failed payments with decline-specific logic, and showing a personalized save flow when subscribers click cancel. Built for Shopify brands running a material subscription program where passive churn and voluntary cancels are eating into MRR.
What Churn Buster does for Shopify brands
- Adaptive dunning retries failed charges using decline-specific logic, recovers revenue native Shopify dunning misses
- Personalized cancel flow intercepts clicks to cancel, saves a portion of those attempts
- Targets two non-overlapping churn events: payment failures & voluntary cancels on same subscriber base
