Profit Leak Audit reads every product in your catalog and reports nine data defects, ordered by what each one loses you: missing weights that make Shopify quote shipping too low, products active in your admin with no page on your online store, live pages that cannot take an order, and missing barcodes, SKUs, images and descriptions. It never invents data: a guess is worse than an empty field.
