Thanks for reaching out back to us, @usercheryle.

Yes, we can assign a class to an employee in QuickBooks Online (QBO) so you can track payroll expenses as provided by ZackE above. However, let me provide you with screenshots to help you follow the steps better.

First, make sure to turn on the class tracking feature. Please note that this is only available in QBO Plus and Advanced.

To assign a class:

1. Go to Payroll.
2. Select Employees.
3. Choose an employee.
   
   
    
4. From the Employment details section, click Edit or Start.
   
   
    
5. In the Workers' comp class field, enter a class.
6. Select Save.
   
   

Currently, the option to assign multiple classes to an employee is unavailable in QBO. That said, I suggest recommending that feature to our product developers by going to the Gear icon and selecting Feedback. 

As a workaround, we can set up different pay types for each worker. Here's how:

1. Go to Payroll and select Employees.
2. Choose an employee and click Edit on the Pay types section.
3. Choose between Hourly, Salary, and Commission only in the Set employee type section and enter an hourly rate.
4. Click + Add pay type to add more and enter an hourly rate for each. You may also rename these pay types.
5. Select Save.

Once done, you may proceed with running payroll for the employee. 

You might also want to set up a direct deposit for your company payroll to avoid the hassle of paying your employees with paper checks.

You can always come back to this thread if you have additional questions about running payroll. You're always our priority. Stay safe!
