SKU.io ABC Inventory Analysis

Upload a sales or orders CSV, such as a Shopify orders export, and the ABC Inventory Analysis ranks every SKU by revenue share (A, B and C) and by how steady its weekly demand is (X, Y and Z). Each SKU gets a combined class such as AX or CZ and a rule-of-thumb stocking policy, so you can see which products drive the business and which are erratic tail items. Revenue comes from a price or line total column, an optional price list, or units if neither exists. Results appear as a sortable table. Files are processed in memory for the one request and never stored. No account is needed.
