Hello @missymarykay55,
You can turn it on and make sure to assign a class to your items when entering and paying your bills. Let me show you how.
- Go to Edit.
- Select Preferences.
- Click Accounting.
- Under Company Preferences, select Use class tracking for transactions.
- Put a checkmark on the Assign classes to selection.
- Select Items.
- Click OK.
In addition, here's an article you can read to learn more about how you can utilize class tracking: How to track account balances using different classes in QuickBooks Desktop?
Lastly, I've also included this reference for a compilation of articles you can use while working with us: Expenses and Vendors for QuickBooks Desktop.
If you have any other questions, please let me know in the comments below. I'll be here to lend a hand.
