Did you find a solution to this? In the same boat here. We create a PO for items ordered, and there is normally a delay between receipt date and invoice date. I want to be able to receive items from the PO into inventory to keep inventory quantities in real time, then be able to match an invoice to that receipt at a later time. Unsure if this is possible in QBO. 

We use an ERP system for our main operation and after inventory is received it moves into "Accrued Inventory" and "Accrued Payable" in the GL. Our inventory management system is updated for the inventory received in real time. Then when the bill is finally received and matched/entered, auto entries are made to reverse the above and move dollars into Inventory and Accounts Payable.
