A Practical Operations Checklist for Paid Chrome Extensions

Operations checklist for billing, support, and release monitoring.

A paid Chrome extension becomes an operations problem as soon as the first customer buys it. The code, billing system, store listing, support flow, and monitoring all need to fit together.

Start with the purchase path. Test checkout, success redirects, receipt email, license delivery, GitHub access if relevant, and the first activation flow from a new browser profile.

Define every license state your UI can show: active, missing key, expired, refunded, canceled, activation limit reached, network error, and server error. The user should see what happened and what to do next.

Prepare support data. You may need purchase email, Polar order reference, GitHub username, license key suffix, extension version, Chrome version, and the last validation time. Do not ask users to send full license keys unless absolutely necessary.

Monitor the critical paths. Watch webhook failures, checkout creation errors, license validation latency, and unexpected entitlement states. Cloudflare logs and Polar webhook delivery status are usually the first places to check.

Treat store updates carefully. New permissions can trigger new user prompts and review questions. Privacy policy changes, analytics changes, and external-service changes should be reviewed with each release.

Plan for recovery. You should know how to resend a repository invite, replay a webhook, deactivate a broken activation, change a customer email, and revoke a license.

The paid-extension experience is larger than the extension package. A reliable product connects billing, entitlement, browser UI, documentation, and support into one maintainable system.
