Actual end state
Record the actual end time, not just when the user clicked Cancel.
First distinguish a scheduled cancellation from an ended subscription. A cancellation set for period end may retain access until that date. When Stripe marks the subscription ended, your app must process the lifecycle event and update its own subscription and entitlement records. Verify both the Stripe state and the local state before revoking access.
This guide covers check 05: Payments and transactional integrity in the Zenveus Production Readiness Standard.
For builders
Cancelling renewal can leave a subscription active until the paid period ends. Your app needs to distinguish that scheduled change from access that has actually ended. Process lifecycle events reliably and calculate access from current subscription state, including other active subscriptions.
A scoped repair request
Use this prompt in Lovable, Cursor, Replit, or Claude Code with the relevant server files available.
Audit Stripe cancellation and feature access. Distinguish cancel_at_period_end from an ended subscription, durably process verified lifecycle events idempotently, handle out-of-order delivery, reconcile current state, and include all subscriptions when calculating access. Work on a branch with synthetic data and mocked external services. Show the smallest diff, identify required adapters and deployment settings, and add allowed and denied tests that prove side effects cannot happen before checks pass. Do not disable security checks to make a test pass.The same failure may appear as
Find the failure layer
Each check removes a class of causes. Keep the first failing result, its timestamp, and the production log beside it.
Record the actual end time, not just when the user clicked Cancel.
Inspect retries and handler logs.
Test from a new authenticated session to rule out stale client cache.
Ranked diagnosis
The webhook branch acknowledges a subscription end without updating the app record.
The UI treats a cancellation request as the end of entitlement or vice versa.
The app never reconciles a local active record with Stripe's ended state.
A cache or client context keeps the old paid tier after the database changes.
Step-by-step repair
Edit your subscription event worker, local subscription table, and server-side feature-access check. Include all current subscriptions when computing user access.
Production safety ruleNever disable access controls, expose service keys, or add wildcard CORS as a routine shortcut.
Decide access for active, trialing, past_due, unpaid, paused, incomplete, and canceled states. A subscription scheduled to cancel can remain active until it ends. Define any grace period as a product rule rather than a browser flag.
Handle customer.subscription.created, updated, and deleted in the verified durable event pipeline. Store the Stripe subscription ID, customer mapping, status, cancellation schedule, and applicable access deadline.
Events can arrive late or out of order. Retrieve current subscription state or serialize reconciliation for that subscription so an old event cannot reactivate ended access. Update the subscription and its entitlement atomically.
Invalidate user access caches after commit. Reconcile local subscriptions with Stripe on a scheduled job. Aggregate access across subscriptions so ending one subscription does not remove a separate valid entitlement.
Implementation example
// Local normalized state, after verified Stripe reconciliation.
function grantsAccess(subscription, now) {
const eligibleStatus = ['active', 'trialing'].includes(subscription.status);
const withinDeadline = subscription.accessUntilMs == null ||
now < subscription.accessUntilMs;
return eligibleStatus && withinDeadline;
}
// Evaluate all of the user's subscriptions and other entitlement grants.
// past_due grace, if offered, needs its own bounded policy.accessUntilMs is your local normalized policy field, not a Stripe SDK field. Derive it using your pinned Stripe API version and applicable item/trial periods. Do not revoke merely because cancel_at_period_end became true.
Prove the repair
Run these checks with synthetic data in your test environment, then repeat the relevant acceptance checks after deployment.
When the built-in AI fix makes it worse
Pause generated changes, restore a known working branch, and capture one failing request with its logs. Change one layer and rerun the allowed and denied checks before proceeding.
Engineering handoff
We trace one production request through the complete path, isolate the failing boundary, and leave behind evidence your team can repeat.
Scheduled renewal cancellation versus an actually ended paid period.
Verified durable events, retries, duplicates, and out-of-order delivery.
Current Stripe state compared with stored subscription records.
Other active subscriptions, entitlement caches, and server-side feature checks.
Typical repair pattern
Scheduled cancellations retain intended access, while ended subscriptions update local state and lose paid privileges.
Before the next release
Clear answers
If cancellation is scheduled for the end of a paid period, continued access can be correct. Check the actual subscription end date.
That can remove access too early. Use the verified lifecycle state and your product's entitlement policy.
Reconcile the local subscription record with Stripe and make replay safe through idempotent processing.
Run the verification checks on this page against your test environment, then repeat the relevant checks after deployment. Example code needs your app's authentication, data model, and configuration; reading the guide alone does not verify your deployment.
