You can either record the items as an inventory or non-inventory items, toddpinil.
Yes, both item type works perfect yet they differ on how they are posted into your accounts.
From your previous replies, you mentioned that you wanted to enter the items as a non-inventory. When you setup a Non-inventory Item, you can enter a sales price and use the COGS account. The information entered will reflect when you create purchases.
You can also look into the transaction journal to see the affected account when you use a purchase order or an invoice.
I'll be here if you need anything else.
