Very similar to receiving your POs in the Skustack App, you will start by going over to the Receiving section.
Select Receive Container from the options and select your desired search option:
By Container ID
By PO#
Search All
Once in the container you can start scanning and receiving products into your receiving bin.
Products that have been received will be split up based on the POs assigned to the shipping container to fully reconcile what was purchased to what was received.
