How do I run a profit/loss report for just one class?

Hello there, @traditionsbr-gma.

I'm here to lend a hand in running profit and loss reports for just one class in QuickBooks Online (QBO).

Here's how:
 

1. Go to Settings ⚙ and select All Lists.
2. Select Classes.
3. Choose the class that you want to open and click the Run report.

You can also check this article for more details: Filter, sort or total reports by Class.

I'm adding these links to guide you with modifying reports and saving their current settings so you won't have to make the same customization:

• Customize reports in QuickBooks Online
• Memorize reports in QuickBooks Online
   

Please know that you're always welcome to post if you have any other concerns about class reports in QBO. I wish you and your business continued success.
