Trial balance cannot agree with profit or loss

Hello there, @qianhui-shophany. Let's determine why your Trial balance doesn't agree with your Profit and Loss report in QuickBooks Online.

Beforehand, I'd like to ask what specific details both reports don't match. Would you mind adding them to this post? I'd appreciate any details you can add to help me get on the same page.

In the meantime, please ensure that both Accounting Methods, including the Report period, were accurate. This can be the reason why information is not matched. You can refer to this screenshot below for your reference:

I've added this resource to learn more about personalising your reports in QBO: Customise Reports.

Also, this article can help you export your data for future tasks: Export Reports, Lists, and More.
