See every featureMarginLab helps Shopify merchants understand where profit is being lost and what deserves attention first. It analyzes store and product economics to reveal weak margins, missing costs, pricing issues and changes in profitability. Merchants can monitor profit health, understand the economic impact of taxes and operating costs, and evaluate potential improvements before making decisions.
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.
