Hello vishmin,

Aside from the Divisions and the Class tracking features, we can also set up sub-accounts to keep track of your transactions. You can use these sub-accounts when creating your expenses.

For the detailed steps on how to create the sub-accounts, you can follow this link: Create subaccounts in your chart of accounts in QuickBooks Online.

Once you've transactions associated to the sub-accounts, you can pull up the Transaction List by Accounts report. From there, you can customize the report to get the accurate data.

We'll be right here if you have additional questions on how to keep track of your transactions. Have a great day!
