You are correct, adding a part # directly to an AP invoice without a PO does not bring in that part's default cost.  I don't believe the system was designed to that.  I can see how that could create issues with people skipping the PO field, or creating new invoices even though inventory receipts have been posted.

Using parts on a 3-2 invoice does bring in the billing info.

You didn't mention whether your company uses inventory.  

As for Purchase Order tracking, the system's primary tracking is the qty field (not the price).  If get invoiced for a part at a different price than the PO, that invoice should not be processed until someone has approved the price variance.  This will then be reflected on a PO audit report.   Note:  The automatic close a PO feature works when all of the qty's have been received, not the price.  

So if you have PO's where you only care about the total price and not the total quantity, then you might consider setting up those PO's a little differently.  You could set the quantity at the lump sum value, and then the price column would always be $1.00.  This would allow you to receive partial invoicing against the value, and still allow the system to technically be tracking the qty behind the scenes.  However, if you do, then you will need to create a custom PO form with those columns re-labeled when issuing lump sum PO's.  I recommend creating a PO type of lump sum for those instances, depending on how your PO types are structured.

Hope this clarifies it for you.
