How do you stop from QB asking you to enter a "class".

Hi carol.fox.

Setting up and using classes is one of the ways QuickBooks Online helps you save time when entering transactions or pulling up information. I'd be happy to help you disable the automatic enter a class warning. 

In order to disable this from always warning you if no class is selected you'd need to follow these steps: Click on the Gear Icon>Account and Settings>Advanced. From there go to categories and uncheck the warn me when a transaction isn't assigned a class box. This'll disable the warning for all future transactions so you'll no longer need to worry about it.

If you have any questions let us know and we'd be happy to help.
