Can you map different earnings to different classes?

Hey there, PSconsulting. Allow me to share some information regarding allocating salaries to different classes in QuickBooks Online.

I know how important it is to allocate an employee's salary to three different classes, however, the option to do so is currently unavailable. You can only assign one class per employee in QuickBooks Online.

Here's how:

1. Click the Gear icon at the upper right corner and choose Payroll Settings.
   
2. Go to the Preferences section.
   
3. From the Accounting Preferences, scroll down to the Classes section.
4. Choose I use different classes for different employees option.
5. Tap OK.
   
6. Assign a Class for each employee by clicking the drop-down arrow.
7. Select a Class from the List.
8. Hit OK.
   

I'd also suggest submitting feedback within your QuickBooks Online (QBO) account. This way, it goes to our product developers to help improve your experience while utilizing the program. See the steps below:

1. Go to the Gear icon at the upper right and select Feedback under Profile.
2. Enter your comments or product suggestions. You can also attach a screenshot or file to combine them all. 
3. Click Next.
   
4. You'll be provided a list of suggested help articles related to your comments. You can read through them or choose Skip and send message.
5. Select the appropriate category from the drop-down menu.
6. Tap Send message.
