Hello there, JCTorrellas. Let me help you fix the issue about your Purchase Order (PO) in QuickBooks Desktop.

When converting a Purchase Order to a bill, the PO window will show as Received in Full. To convert partial items, simply edit the quantity in the PO.

Here's how:

1. Open the Purchase Order.
2. Under the Recent Transaction, then click bill.
3. Edit the quantity of the item.
4. Click Save & Close.

If someone mistakenly closes a Purchase Order (PO), all the items listed in it will also be marked as closed. To fix this, you just need to change the status of the PO to open, and then it will appear as a billable transaction.

To do this, follow these steps:

1. Go to the Vendors menu and then select Vendor Center.
2. Locate the vendor you created the purchase order with.
3. On the All Transactions drop-down menu, select Purchase Orders.
4. Find the closed purchase order and double-click to open it.
5. Click Mark as Open and then select Save & Close.
