Suppliers send orders as CSV or Excel files in their own layout. PO Importer lets you map each supplier's columns once, then reuses that mapping for every file they send. It matches lines to your products by exact SKU or barcode, remembers the supplier SKUs you confirm, turns cases into units, and flags when a supplier's per-unit amount differs from their last order. Problems like unmatched or duplicate lines are shown before you download a file ready for Shopify's purchase-order import.
