We've been told by a grantor to enter a PO so we can bill them for reimbursement of a purchase.  I know that purchase orders don't hit the books until they are received and that normally you would just enter a bill or accrue it, but I wonder if you could tweak the the items to force an entry into the income statement. The reason I'm asking is that they specifically said to use a purchase order to encumber the funds.  Any ideas?
