How do you handle purchase orders for non-inventory items. Two examples - 1) the office heater is broken, we call repair shop to fix it - PO needs to be created to match up with billing invoice,do you just use a comment field?   But do you still have to "receive" the PO?   2) we order toner for 6 different printers - do you enter each as a part number?  I am trying to use product lines to differentiate but this doesn't print on the PO so receiving doesn't know what is inventory and what is just expense.  Thank you.
