Missing Cost Audit

When a product has no cost per item, Shopify reports that cost as $0.00 and books the whole sale as profit. It does not warn you. On a store where half the catalogue is missing costs, Shopify's own AI calls the margin "healthy".Free, forever, no SKU limit: find every variant with no cost, see how much recent revenue has none behind it, and export the list.Keep ($29): margin as a range, set costs in the app, import history, alerts. Pro ($79): price list import, auto-restore, landed cost.
