Churn Buster alternative: NoChurn vs Churn Buster

Churn Buster has focused on failed payment recovery for a long time, and it has grown a cancel flow product alongside it. It is especially at home with e-commerce subscription brands running on Shopify-based subscription apps. NoChurn is built for SaaS and subscription businesses on Stripe, or on any billing system through a REST API, and charges one flat price based on MRR.

Where Churn Buster is a good fit

• You run an e-commerce subscription brand. Churn Buster integrates with many Shopify-ecosystem subscription apps such as Recharge, Skio, Loop, Stay.ai, Ordergroove and Seal. NoChurn does not have native connectors for these; you would use our API.
• Failed payments are your main problem and you want a specialist. Churn Buster has spent years on recovery campaigns. On many platforms it controls retry timing and adapts it to decline codes, and on Stripe and Braintree it charges an updated card right away.
• You want SMS in the recovery sequence. Churn Buster offers optional SMS. NoChurn recovery runs over email.
• You want to measure before you pay. Their free Measure mode lets you baseline recovery results before switching on the paid product.

Where NoChurn is different

Flat price by MRR. NoChurn is free until $300 MRR, then from $9/month, in small steps up to $399/month at $500k MRR, with custom pricing above. Details on the pricing page.

Every feature on every plan. Recovery, cancel flows, win-back, custom data, churn score and API are all included from the free plan.

Never a cut of recovered revenue. You pay for your size, not for what we recover.

Stripe, or any billing through the API. Stripe connects in one click. Without Stripe, you keep your billing and send subscriptions, payments and cancellations to our REST API. Chargebee, Recurly, Paddle, Braintree, Mollie, the App Store, Google Play and more connect directly too.

AI-written recovery emails you approve. Emails go out on days 0, 3, 7 and 14 by default, in the customer’s language (English, German, French, Italian or Portuguese). Retries can be timed to likely paydays and the customer’s local time, or you can keep Stripe Smart Retries. Replies are read, sorted, and answered or sent to your team. The card update page is hosted, and card data stays with Stripe.

Churn score at signup. Each new customer gets a 0 to 100 score from their payment method, signup source and your custom data. Prepaid and disposable virtual cards count as high risk; neobank cards as medium; Stripe Link, Apple Pay, Google Pay, bank cards and SEPA as low. When a customer removes their card before renewal, NoChurn starts a save flow before the payment fails. See churn score.

Click-to-cancel built in. The cancel flow goes reason, matching offer, confirm, and a one-click “cancel now” is visible at every step.

Headless and MCP. Use the hosted modal with your theme and custom CSS, or go fully headless and render reasons and offers in your own web, desktop, iOS or Android UI. Coding agents can integrate NoChurn through our MCP server. See headless and MCP.

Churn drivers from your data. Send attributes like signup source, plan or key usage, and NoChurn shows which ones go with churn, with sample size and confidence. Correlation, not cause. See custom data.

NoChurn is new and has no customer results to cite yet. Churn Buster has a long track record in recovery.

Switching from Churn Buster

There is no import tool, so switch in steps:

1. Connect Stripe in a few minutes with the quickstart. If you are on another platform, plan the API integration first.
2. Check your Stripe retry settings. Churn Buster asks Stripe users to set specific failed payment settings. Review them before NoChurn takes over, and decide whether NoChurn times retries or you keep Stripe Smart Retries.
3. Avoid double emails. During a test period, run both tools on separate customer groups so nobody receives two recovery sequences. Make sure Stripe’s own failed payment emails are off if a tool is emailing.
4. Rebuild your cancel flow. Copy your reasons and offers into NoChurn and add the win-back emails for each reason.
5. Compare the same weeks. Look at recovered payments, saves and replies, then keep one tool.
