Can you keep several reports open so can switch between them as needed?

Yes, you can definitely do that, anthea-accpro-co.

You can open each report in a different tab. This will be easier for you to switch between them. Here's how to do it:

1. Go to the Report menu.
2. Find the appropriate report you want to open.
3. Right-click the name of the report
4. Select Open link in new tab.

I'm also adding these articles to help speed up the reporting process in QuickBooks Online: 

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