Hey emmatch,

I'm happy to see you're looking to maximize the power of QuickBooks Online by multi-tasking in multiple companies! Currently, the system is designed to provide a consistent experience for the company you're signed in to. As your session is stored in your browser window, the best way to work on multiple accounts is by using a separate browser for each one (such as Chrome and Firefox). If you have any feedback about this, don't hesitate to submit it directly to our engineers.

Let me know if I can help with anything else.

@emmatch 

Open your first QBO on the main browser, second QBO on the private/incognito browser.

I have 7 companies I work with every day.  Are there enough browsers out there.  So stupid that Quixkbooks did away with on line app

@howiefish 

Firefox, Chrome, Edge, Safari, Opera, Vivaldi

Thats 6 and a royal pain in the A**.  Still short one.   Hopefully a 3rd party app is developed that allows multiple companies and tabs open at the same time......

As I said earlier, you can utilize the main browser and the incognito/private browser. 6 browsers = 12 QBO accounts. Do you need more?

Did not see the incognito thing.  how do I do that?

Thanks for posting here again, @howiefish.

I'm joining in this thread to share additional insights with you. Use these keyboard shortcuts to launch a new private window depending on your browser:

• Google Chrome: press Ctrl + Shift + N  
• Mozilla Firefox: press Ctrl + Shift + P
• Safari: press Command + Shift + N

From there, open your accounts by going to QuickBooks Online site.

Post here anytime if you have other program concerns or additional questions about accessing multiple QuickBooks Online account. Have a nice day!

Thank you,  Its still such a half A*S work around for a problem Intuit created
