Product costs

I can share some info about your concern, @ryan_s1111.

QuickBooks is designed to follow the First In, First Out (FIFO) when tracking the inventory. Means, it will calculate depending on the cost of the item entered when recording it. This will not depend on the cost entered when a product is set up under the Product/Services menu.

Since there are no actual costs for the products you purchased, you can manually create the transactions for the project. Then, enter the cost or rate of the product in the specific transactions. You can also skip the Cost field under Purchasing information when adding a new product in QBO.

To track what products you've sold, you may refer to the steps in this article: Track What You've Sold: Products & Services. 

Keep me posted here if you have further concerns about managing your inventory in QuickBooks. I want to ensure your success. Thanks for coming to the Community and take care.

We don't do any inventory as we don't stock anything....order as we need for the most part (don't want to get into any accounting with inventory!).  

We record the purchases as a mass purchase, not individual.  I.e we buy 4 cameras we record that whole purchase as 'cameras'.  So I guess the individual product cost really is irrelevant then...
