Hi Accounts661. Yes, you can open different sections in separate browser tabs since QuickBooks Online (QBO) is a web-based application. To do this, right-click on the section or menu item you would like to open in a different tab and select Open link in new tab.

Please note that data does not sync across tabs automatically because each tab operates independently. You'll have to refresh or reload the page to see the latest updates.
If you have any questions, don't hesitate to reply here.
