Hi @Kevans27,

Thank you for posting here in the Community. I know how important it is to balance your accounting books. To help you fix this, you'll need to make sure the items included in the inventory assembly are set up correctly to their appropriate accounts. Let me guide you how:

1. Go to Lists, and choose Item List.
2. In the list of items, double-click the item that needs to be corrected.
3. Choose the appropriate 'cost of goods sold' account in the COGS Account drop-down arrow.
4. In the Income Account drop-down arrow, select an 'income' account.
5. Click OK.
6. If you are prompted with an Account Change pop-up window, select Yes.

The screenshots below show you the third to sixth step.

Let's do these steps in all your inventory and non-inventory items, as well as your inventory assembly itself, to make sure they are set up accordingly.

You might need to record an adjustment every now and then, you can refer to this link: Adjust your inventory quantity or value in QuickBooks Desktop.

Please know that I'm here anytime you have other concerns.
