DeclineKit vs. Churn Buster

Churn Buster is a long-running failed-payment recovery tool with campaign builders, cancel flows and a team that has tuned dunning for years. DeclineKit does one job: when a Stripe renewal is declined, it gets the customer to enter a working card. If that’s the job you need done, here’s how the two compare.

Not sure you need either?

Run the free audit first. It reads your last 90 days of Stripe invoices with a read-only key and shows how much declined cards cost you. If the number is small, Stripe’s Smart Retries and built-in emails may be enough.
