Thanks for getting back to us, @meickelbeck.

In QuickBooks Online (QBO), you have the option to assign classes to each of your employees. However, as mentioned by my peer Rasa-LilaM above, you can't assign classes to an account. Here's how:

1. In your QBO account, go to the Payroll Settings.
2. Click Accounting under the Preferences section.
3. Go to the Classes section, and select I use different classes for different employees. Then, click OK.
4. In the Preference - Employee Classes, define the class for each of your employees.
5. Click OK once finished.

I'm adding this article for more details: Create and assign employee classes.

In the future, you might want to run reports by class to review all your transactions associated with a class.

I'm still open to your replies. If you have additional questions about assigning classes to an employee. Have a great day ahead!
