In their own words
Churn Buster
Churn Buster helps subscription businesses recover failed payments and understand or reduce cancellations. Its dunning service coordinates payment retries with branded email and SMS prompts asking customers to update their cards. Rolling Analysis assigns each failed payment one of four outcomes and counts a recovery only when the payment clears. For cancellation saves, Cancel Flows asks customers why they are leaving, presents offers matched to those reasons, and reports exit feedback. It includes Smart Offers, A/B testing, segmentation, Sentiment AI, and an optional one-click cancellation path. The company lists integrations including Stripe, Recharge, Shopify, Loop, Skio, Recurly, and Braintree, among others, and supports custom API setups. Churn Buster says it serves mid-market and enterprise subscription brands in ecommerce, SaaS, membership, and digital subscription businesses. Its free Measure plan includes recovery analytics, baseline comparison, and Churn Buster MCP. Dunning or Cancel Flows starts at $269 a month; Dunning & Cancel Flows starts at $430 a month. Both are flat monthly fees based on MRR tier, month-to-month, with no contract. The company says its team responds within one business day through email, chat, and video calls.
