Continue selling is not a backorder report.

Shopify Products → Export includes Variant Inventory Policy. continue plus zero On hand (or Variant Inventory Qty) still takes money. Shopify does not give you that list. Drop the file on the one-file check. This is for the person who has to ship — not a shopper waitlist, and not a Shopify app.

Open the backorder check Inventory CSV (On hand)

How

1. Shopify admin → Products → Export. Keep SKU, Variant Inventory Qty (or On hand), and Variant Inventory Policy.
2. Drop the file on backorder.html (or paste the table). Try the Shopify sample first if you want to see the shape.
3. Rows with inventory still on hand are skipped. deny is not a backorder. The file stays in this tab.

WooCommerce uses Backorders allowed? yes/notify instead. Same checker. Drafts with stock: unpublished stock. Low stock: Shopify low stock.
