Inventory is not updating after receiving a PO

When you confirm a receipt in PO Flow, Shopify inventory should update immediately. If it is not updating there are a few things to check.

Check if the line item is linked to a Shopify product

Inventory only updates for line items that are linked to a Shopify product variant. If a line item was added manually (e.g. typed in rather than selected from the product search) and does not have a Shopify variant ID attached, inventory will not update. Look for a warning banner on the PO that says certain items are not linked to Shopify products.

Check the correct location was selected

When receiving stock you select a location. Make sure you selected the correct Shopify location. Check your Shopify Admin → Inventory to confirm which location the stock was added to — it may have gone to a different location than expected.

Check that inventory tracking is enabled on the product

Go to the product in Shopify Admin and make sure Track quantity is enabled for the variant. If inventory tracking is turned off for a variant, Shopify will not accept inventory updates for it.

Check the drop ship setting

If the PO is set to Drop Ship, inventory is intentionally not updated because the goods do not physically arrive at your location — they go directly to the customer. Check the PO fulfillment type setting if you expected inventory to be updated.

Check for errors in the activity log

Open the PO and view the activity log. If the inventory update failed there will be an error entry in the log with details about what went wrong.

Still not updating

Contact PO Flow support with your store domain and the PO number. Our team can investigate the specific receipt and Shopify API response to identify the cause.
