Is every no-expiry Stripe coupon a revenue leak?

No. Some permanent discounts are intentional, such as grandfathered accounts or contracted plans. LeakCheck flags coupons and discounts that deserve review, then the founder decides what action is appropriate.

Can LeakCheck change or remove a coupon?

No. LeakCheck uses Stripe read_only OAuth or a Stripe JSON export upload. It cannot edit coupons, subscriptions, invoices, or customers.

What else does LeakCheck check besides coupons?

LeakCheck checks six leak types: failed charges, stale or dead trials, no-expiry coupons, duplicate customers, past-due subscriptions, and mismatched invoices.

Stripe no-expiry coupon audit

Find permanent Stripe discounts before they keep leaking revenue.

A coupon with no end date is not always wrong. It becomes a problem when a launch promo, trial save, or manual make-good keeps applying long after the reason is gone.

Manual check

What to inspect before you call a discount harmless.

Coupon drift usually starts as a reasonable exception. The audit question is whether the discount still matches the customer, plan, invoice, and promise that created it.

Coupon duration

Look for forever discounts, blank redemption windows, or coupons that no longer match their campaign name.

Where it is attached

Check whether the discount sits on the customer, subscription, invoice, or promotion path.

Active subscriptions

Review whether discounted accounts are still on paid plans where the promo was meant to end.

Recent invoices

Confirm the discount is still reducing real invoices instead of only sitting on inactive records.

Plan changes

Check whether a plan upgrade carried an old coupon onto a higher-priced subscription.

Owner decision

Separate intentional lifetime discounts from cleanup work before anyone touches billing.

Coupon drift

Some permanent discounts are fine. Some need review.

LeakCheck does not decide your pricing policy. It gives you the account-wide list so you can make the decision with evidence instead of memory.

intentional

Grandfathered customers

A permanent discount may be part of a real promise. Mark it as reviewed before changing anything.

Contracted discounts

Annual, partner, or make-good discounts may need to stay in place until a renewal conversation.

Launch promos

Old launch codes can keep reducing invoices long after the campaign finished.

Save offers

A churn-save discount can become permanent if it was never given an end date.

Customer-level discounts

Discounts attached to a customer can keep applying as subscriptions change.

Duplicate records

Repeated customers can split context, so one record looks discounted without the reason nearby.
