What is CostGap?

Shopify profit reports leave out every sale of a product with no cost per item, and a cost of 0 makes a product look like pure profit. CostGap scans your catalog and last 30 days of orders, shows how much of your sales has no cost recorded, and lists every variant that needs one, best sellers first. Type a cost and press Enter to save it to Shopify.

By the numbers

Who runs it

Off-siteRuns in your Shopify admin and on a schedule, not in storefront code, so a storefront scan has nothing to count. No adoption number, no pick.

From our Oct 9, 2026 storefront scan. Top-graded = the 20 highest Brand Tested Scores with Tech Stack left out, so the stack never grades itself (why).
