# Churn Buster

> Churn Buster recovers more of the revenue subscription businesses lose to failed payments (dunning) and keeps more customers at the moment they try to cancel (cancel flows). Since 2013, more than 1,000 subscription businesses have used us to push recovery past what native billing tools reach on their own. Working measurement-first, we find your recovery ceiling, the math on what's recoverable from failed subscription payments, and get you as close to it as we can.

The work that moves a recovery rate is retry tailoring, campaign optimization, and hands-on retention specialists, the part billing platforms don't do. Instead of promising the impossible, we show you where your ceiling is and how much of the remaining gap is worth closing. Our pricing is a flat fee based on your MRR tier, so our incentives stay aligned as your recovery improves.
