price lists without inventory

SOLVED

Is it possible to set up price lists from vendors without treating it like inventory?   I have a client who purchases supplies from a few regular vendors and he'd like to be able to have a price list so when the purchase invoices are created he can just select them from the list rather than typing in the prices.  He does not keep any inventory rather the purchases are used right away on job sites.    I have not really used the inventory feature before, but as I understand it's really designed for companies who purchase items for resale.   He had another person doing the books for a few months and she doesn't really know bookkeeping.  She created, with his help, a whole bunch of inventory items.  When she created the purchase invoices it was debiting the inventory account and crediting accounts payable.  However, when he creates his sales invoices he does not touch the inventory accounts as his price to his clients is usually a figure that includes all labour and materials and is allocated to a sales revenue account.   As a result the inventory account balance keeps increasing and none of the items he purchased for jobs is ending up in an expense account.  

From what I know about inventory, he would have to break down his sales invoices into labour and materials and list each item from inventory he used on that job in order to credit the inventory account would he not?
