Hi there, @ELIVI.

Currently, we can only assign classes to Accounts Payable (A/P) by creating a check or an expense transaction, while the bill payments dont.

Also, please know that there isn't a specific Balance Sheet report that's showing by class.

Here's how you can assign classes to your Accounts Payable (A/P) transactions:

1. Click the + New button, then select Expense or Check.
2. Choose the payee from the drop-down and the bank account in the Payment account drop-down.
3. In the Category column, select the Accounts Payable (A/P) account from the drop-down.
4. Enter the necessary information, then amount.
5. From the Class drop-down, select which class you want to assign the transaction.
6. Click Save and close.

Once done, you can now run the Balance Sheet Detail report to see the assigned classes to your A/P transactions.

You might want to check out these articles to learn more about class tracking and what specific reports you can run:
