What to do if supplier doesn't accept PO but ships the goods?

I would like to know what other do in the following scenario. Supplier is sent purchase order acceptance email. Without accepting the PO the supplier sends the goods and they are being received by the requester. Now the PO needs to updated as "Accepted" by the buyer as it will keep showing acceptance required. Is there a better way to handle this? Can we update acceptance required on the background based on receiving.

Thanks
