Configure inventory tracking and identifiers
On the Variants & Inventory tab, turn stock tracking on, allow backorders and set the UPC, EAN, GTIN and MPN identifiers.
Inventory settings decide whether the app counts stock for a product, and they hold the trade identifiers marketplaces ask for. Both live on the Variants & Inventory tab.

How do I turn on stock tracking and set identifiers?
- Open a product and click the Variants & Inventory tab.
- Tick Track inventory for this product to count stock and show available quantities.
- Tick Allow backorders when out of stock if you'll keep selling past zero.
- Under Product Identifiers, fill in UPC, EAN, GTIN and MPN as needed.
- Click Update Product to save.
Should I track inventory for every product?
No. Leave tracking off for services or virtual items you can never run out of, and you won't get false low-stock warnings.
Tip. These identifiers apply to the primary SKU. On variant products you manage each variant's identifiers individually in the grid.
