Discounts that cost more than they earn: a coupon audit for online stores

Discounts are the easiest growth lever and the easiest way to give away margin without noticing. A short coupon audit tells you which codes are working and which are just leaking.

Codes with no end date

A launch code from two years ago that still works is a permanent price cut. List every active code and give each one an expiry date.

Codes that leaked to coupon sites

Influencer or one-time codes often end up on public coupon sites. If one code suddenly has far more uses than its campaign could explain, it has leaked. Replace it with unique single-use codes.

Stacking that makes orders unprofitable

Combining a sitewide sale, a coupon and free shipping can push an order below cost. Check your store settings for which discounts can combine, and test the worst case on your lowest-margin product.

Coupons nobody uses

Large numbers of expired, unused coupons mean the offer never reached people or was too complicated. Fewer, clearer offers convert better and are easier to track.

Automate the check

Revenue Leak AI reviews coupons in Shopify and WooCommerce on every audit and flags expired, unused and overused codes with an estimate of what they cost you.
