Hi there 67FARMER,
In order for your books to be correctly balanced, it's key to know how to enter your transactions involving any used materials. QuickBooks Desktop is a great tool able to help you keep track of various items in order to help you enter them in your sales and expenses. I can point you in the right direction for assistance with entering these transactions.
When entering these transactions, you could use the items you created for them and just adjust the prices associated with the sale in order to correctly reflect the amount of the sale. For further information regarding how to keep track of these transactions so that all of your books are well balanced, I recommend reaching out to your accountant. They'll be able to guide you in how to enter those transactions correctly so that they correctly affect the accounts needed to be affected. If you're looking for an accountant near you with experience using QuickBooks, you can find one on our Find an accountant page.
If you have any other questions, feel free to reach out here.
