Hello there, @reybrz.

There's no need to worry. I'm here to ensure you can get through this and access QuickBooks Online (QBO) company. Before anything else, we'll want to rule out the possibility of having issues with the browser itself. Know that when a browser is full of temporary internet files or Cache and cookies, it can affect your browsing experience and sometimes lead to your operation getting stuck or stopping.

To get this fixed, you'll want to access your account in an incognito or private window. You can use the following shortcut keys to access an incognito browser:

• Chrome: Ctrl+Shift+N
• Firefox: Ctrl+Shift+P
• Safari: Command+Shift+N

Once you're in, try to access the invitation link. If it works and you're able to access the account, you can proceed to clear your browser's cache. Refer to this article for the steps: Clear cache and cookies to fix issues when using QuickBooks Online.

You can also use other compatible browsers if the issue persists. Refer to this article to see the list of compatible browsers in QuickBooks Online: Other browsers.

Now, if the issue persists. I'd recommend contacting our Customer Care Team, so they access the account in a secure environment and determine the root cause of the problem. See this article for more details: QuickBooks Online Support.

Moreover, here's an article to help you ensure data stays accurate inside the company file: Run reports in QuickBooks Online.

@reybrz, please don't hesitate to comment below if you need further assistance accessing QuickBooks or performing specific tasks inside the program. I'll be here, ready to help you out again. Stay safe, and have a nice day!
