Available on Standard and above. Open Update inventory and confirm the Shopify location before adding products.
Choose Increment to add units, Decrement to remove units, or Set to enter a target quantity.
Check the Inventory mode. Available is stock free to sell; On hand includes available, committed and unavailable stock. For a physical shelf count, make sure the count and selected mode describe the same stock.
Scan products or use Manually select products. Correct the row quantity or remove an accidental row before saving. To start from a spreadsheet, use Import CSV while the working list is empty.
Review the product variants, quantities, location and resulting changes. Select Save update, then complete any reason/note confirmation.
Check the result. If some products fail, review the failed rows and retry those items; do not repeat the whole original update blindly.
Changes are sent to Shopify when you save the update, not simply when a product appears in the working list. If Shopify reports that stock changed while you were working, review the refreshed quantity before applying an On hand set.
To reverse a saved mistake, see Undo inventory updates.
