Hello there, jenbookkeeping.
I'd love to help you with setting up classes in QuickBooks Online. However, the Class tracking feature is only available in QuickBooks Online Plus. Once you're ready to have this feature, we can upgrade your current plan to QBO Plus. I'll show you how:
- Sign in to QuickBooks Online as a primary or company admin and go to the Gear icon.
- Select Account and settings.
- In the Billing & Subscription tab, make sure your payment info is up-to-date.
- In the QuickBooks Online section, select Upgrade your plan.
- Choose Plus and then select Choose plan.
- Follow the on-screen steps to upgrade your plan.
Once done, we can turn on this feature from the settings to start creating a class for each segment in your business. Here's how:
- Go to the Gear icon.
- Select Account and Settings.
- Select Advanced, then select the Categories section to edit.
- Check Track classes. Apply all the information you want.
- Click Save. Then, Done.
