How many classes can be created/used in QBO?

Hello, mark111.

In the US version of QuickBooks Online, you’ll be able to create up to 40 classes for the Plus subscription. In Canada, there isn’t a specific limit when creating classes. I did try to replicate the scenario and I was able to create more than 40 classes in my QBO Canada. However, you can only use one class per item when creating a transaction.

For additional information about classes, please refer to this article: https://quickbooks.intuit.com/community/Getting-Started/How-to-set-up-and-use-class-and-location-tracking/m-p/191381
