churn-prevention makes Claude act as a SaaS retention expert. It covers voluntary churn (customers who cancel) and involuntary churn (failed payments) with a cancel flow, exit survey, dynamic save offers, risk signals, a health score model and a dunning sequence.

It loads when you mention churn, cancel flows, save offers, dunning, win-back or "customers are leaving". It asks for your churn rate, subscriber count, billing provider and constraints first. It bundles two reference files and no scripts.

Good for

  • SaaS founders losing subscribers who want a cancel flow
  • Product and growth teams designing save offers and exit surveys
  • Billing owners fixing failed payments and dunning emails

What's in the skill

When it loads

When the user wants to reduce churn, build cancellation flows, set up save offers, recover failed payments, or implement retention strategies. Also use when the user mentions 'churn,' 'cancel flow,' 'offboarding,' 'save offer,' 'dunning,' 'failed payment recovery,' 'win-back,' 'retention,' 'exit survey,' 'pause subscription,' 'involuntary churn,' 'people keep canceling,' 'churn rate is too high,' 'how do I keep users,' or 'customers are leaving.' Use this whenever someone is losing subscribers or wants to build systems to prevent it. For post-cancel win-back email sequences, see emails. For in-app upgrade paywalls, see paywalls.

Questions

What does churn-prevention do?

It helps Claude plan how to keep subscribers: a cancel flow with save offers, early-warning signals, and a failed-payment recovery sequence.

How do I install churn-prevention in Claude Code, Claude or Codex?

Use the install box at the top of the page and pick Claude Code, Claude or Codex. Claude Code and Codex read skills from a folder on your machine. In the Claude app you upload the skill folder as a zip.

Does it connect to Stripe or my billing system?

The skill bundles no scripts and names no API key. SKILL.md names billing providers such as Stripe, Chargebee, Paddle and Recurly so Claude can tailor advice, and lists CLI tools such as stripe and posthog as related tools. It bundles nothing that connects to them.

Does it write win-back emails?

Not post-cancel win-back sequences. SKILL.md sends those to a separate emails skill and in-app upgrade paywalls to paywalls.

Is it safe to use?

It is instructions and two reference files, with nothing to run. Test any cancel flow or offer it designs before it reaches customers.
