Inventory is not updating

Shopify on-hand inventory only changes when you record a receipt against a PO. If you expect inventory to be higher after a shipment arrived, work through this checklist.

Did you receive the stock in PO Flow?

Editing a PO does not change inventory. Inventory only moves when you click Receive Stock, set quantities, and confirm. Open the PO and check the Receipts section for a receipt covering the shipment.

Was the right location selected?

The receive modal asks you to pick a location. Inventory is increased at that location only. If the receipt went to the wrong location, use Delete Receipt and re-record the receipt at the correct location.

Are the quantities correct?

Use Correct Receipt to adjust the quantities recorded on a receipt without deleting it. Inventory is adjusted by the difference.

Is the variant tracked in Shopify?

If the variant has inventory tracking turned off in Shopify, PO Flow cannot change its on-hand level. Turn on inventory tracking on the variant in Shopify and try again.
