Churn Buster

Churn Buster is subscription software for recovering failed payments and saving cancellations through targeted offers. It suits subscription businesses that want both workflows, particularly mid-market and enterprise brands; the free Measure plan is useful for assessing recovery performance, while paid use starts at $269 a month.

Overview

Churn Buster combines dunning with cancellation flows. Its dunning coordinates payment retries with branded email and SMS prompts for customers to update their cards. Rolling Analysis classifies each failed payment into one of four outcomes and counts recovery only after the payment clears, giving teams a concrete measure of recovered revenue.

Cancel Flows gathers cancellation reasons, presents offers matched to those reasons, and reports exit feedback. The two products address different points in subscription loss: failed charges and deliberate cancellations. A business needing only one can start with that product; the combined plan costs more but brings both into one service.

Key features

• Payment recovery: Coordinated retries and branded card-update reminders provide a structured response to failed payments. Recovery measurement counts cleared payments, making the reported outcome more grounded than treating an attempted retry as a recovery.
• Cancellation saves: Smart Offers, segmentation, A/B testing, and Sentiment AI support tailored save flows. An optional one-click cancellation path gives businesses a way to let customers leave directly.
• Integrations: Supported services include Stripe, Recharge, Shopify, Loop, Skio, Stay AI, Seal, Ordergroove, Smartrr, Awtomic, Recurly, Braintree, Checkout Champ, Rivo, Subbly, and Inveterate. Custom API setups extend the options for other systems.
• Billing and operations: Dunning automation and multi-currency billing are supported, along with a customer billing portal. The service is available through web and API platforms.

The company says its team can set up an account in about an hour, and that paid accounts receive account reviews and ongoing optimization. It also says support responds within one business day by email, chat, and video calls. These services add practical guidance for teams that want help refining recovery or cancellation flows.

Pricing

• Measure — free: Includes recovery analytics, baseline comparison, and Churn Buster MCP. It is a no-cost way to measure recovery, but it does not include either paid product.
• Dunning or Cancel Flows — starting at $269 a month: Includes one product, with a flat monthly fee based on MRR tier. This is the entry paid option for a business focused on failed payments or cancellation saves. It is month-to-month with no contract.
• Dunning & Cancel Flows — starting at $430 a month: Includes both products, also at a flat monthly fee based on MRR tier. It fits businesses that want to manage failed-payment recovery and cancellation saves together. It is month-to-month with no contract.
• Advisory — $2,500, paid once: A one-time, MRR-based engagement with 60 days of measurement, a benchmark report, and a one-hour review. It suits teams seeking a bounded analysis rather than an ongoing paid product plan.

Paid plans can be cancelled at any time. Because the monthly starting prices vary by MRR tier, businesses should account for the tier-based fee when comparing the entry price with their likely cost.

Platforms

Churn Buster supports API and web access. Its integration roster spans subscription and payment services used by ecommerce, SaaS, membership, and digital subscription businesses.

Who it's for

Churn Buster is aimed at mid-market and enterprise subscription brands. It is a strong fit for teams with recurring billing that want to act on both failed charges and cancellation intent, especially when their stack includes one of its named integrations or can connect through a custom API setup. The $269.00 USD monthly starting price makes it a less natural fit for a small operation seeking a low-cost billing tool alone.

Pros and cons

• Pros: The free Measure plan offers recovery analytics and a baseline comparison without a paid commitment.
• Pros: Businesses can buy dunning or cancellation flows separately, then choose a combined option when both workflows matter.
• Pros: Recovery is counted only when a payment clears, and cancellation offers can be tested and segmented.
• Pros: The company describes paid account reviews, ongoing optimization, and a one-business-day support response target.
• Cons: Paid access starts at $269 a month, with the final flat fee tied to MRR tier; that entry point may be hard to justify for smaller subscription businesses.
• Cons: The free plan measures recovery but does not include the dunning or cancellation products themselves.

Verdict

Look elsewhere if you need a free tool that performs billing recovery, or a lower-cost general billing platform.
