A stock error is whenever a count for an item increases from one inventory to the next, without an invoice to account for the increase. Another name for this is "negative consumption".

Consumption = (Beginning Count + Invoices) - Ending Count

This can also be because of a miscount from a previous inventory, or an error when adding an invoice.

When submitting an inventory count, you're notified of any stock errors.

To see just your stock errors, you can toggle on the "View stock errors" filter.

Having a stock error won't prevent you from submitting the inventory, but you should take steps to correct it before you submit, or immediately after the inventory.
