Hi @HomeEcGuy,

Let me give you some insights using the inventory for the project. You have to create an Invoice for the inventory you wish to take and use to the project.

I recommend that you can also use the advice of what @vpcontroller’s provided above.

You can visit this article for some details on how to add transactions for the project: Set up and use the Projects feature.

If you have any other concerns, don't hesitate and come back to the Community. Take care.
