Let's make sure we have the classes feature turned on, meickelbeck.

I can help you assign classes to your employees.

It's possible that you haven't turned no the class tracking feature yet. One possible reason can also be that your subscription plan is Simple Start or Essentials, I recommend upgrading to QBO Plus or Advanced. I'll show you how to verify your account settings.

2. From the Billing & Subscription menu, look into your QuickBooks Online plan.
3. Then, click the Advanced menu to check if your class tracking option is turned on.
4. Click Categories​​​​​​. Ensure that the Track classes feature is turned on.
5. Select Save and then Done.

After checking, you can follow these steps on how to assign classes to your employees.

2. Scroll down to the screen and click the pencil icon under Accounting.
3. You'll see the Class Tracking section. Click the pencil icon to turn on and start assigning classes.
