QB uses "Quantity" for determining closure of a purchase order. For similar orders, such as Blanket or non-routine Purchases, we do the following to keep the PO open:
Upon Creation of Vendor PO
Quantity Field = Total Amount for Blanket Order
Rate = 1.00
Total will still be the same.
Applying an invoice to the PO:
Received invoice for $300
Go to Receive Items and Enter Bill
Quantity Field = 300
Cost = 1.00
But you will have to Manually close the PO once completed (but doesn't matter as it it non-posting anyhow)
Hope this helps some!
