Shopify keeps one cost per inventory item. When you change it, the old value is replaced, so earlier margins stop matching. CostSonar records cost changes from its first check and keeps a dated history. It sorts your catalogue into variants selling below cost, variants with no cost set, and variants on a thin margin. Archived and draft products are skipped. Access is read-only. The app never writes to your store.
