In retail, there are several cases where the vendor may invoice a customer for an inventory item with a quantity higher than the original Purchase Order (PO) and/or Product Receipt. E.g. PO was raised for an inventory item quantity of 10, Product Receipt was completed for that item for a quantity of 10 (many large operational issues can contribute to this) and when the invoice comes from the vendor the quantity for the item is 12.

There are other matching policy options in Accounts Payable setup, including the ability to have a matching override (which is vendor specific). However, even with a matching policy override by vendor, the system still requires over delivery to be configured and the over delivery percentage set on the item. The issue here is that an item can have many approved vendors. So even if the override matching policy is vendor specific, to get that to work your customers need to open the door to over delivery on the item, which in most cases means we lose further receipting control.
