One product export. List SKUs whose stock is below zero — WooCommerce Stock, or Shopify Variant Inventory Qty / On hand. Shoppers may still see “in stock”. This is for the owner who has sold units that are not on the shelf. The file stays in this tab.

Or paste a table from Google Sheets / Excel (tabs or commas). Nothing is uploaded.

Variable parents and unpublished rows are skipped. Zero is not negative — that is stock mismatch when the status still says in stock. Drafts with leftover qty: unpublished stock.

What this is not

Not a purchase-order tool. We do not invent a reorder quantity.
Not trapped-dollar math. We do not invent cost without a cost column.
Not a missing-image catalog check. That is csv-check.html.
