GOOD DAY. I AM HAVING DIFFICULTY OPENING QUICKBOOKS. IF YOU HAVE A CALL CENTRE NUMBER I CAN CALL TO HELP I WOULD REALLY APPRECIATE IT. THANK YOU.

Welcome and thanks for posting the Community, @fourrivers1-outl.

To check if this is a browser-related issue (cache and cookies), try signing into your QuickBooks Online (QBO) using a private browser (incognito).

Here's how:

• Press Ctrl + Shift + N (Google Chrome).
• Ctrl + Shift + P (Firefox).
• Control + Option + P (Safari).

If you're able to open your account, return to your default browser and perform a clear cache to refresh the system. However, if the issue persists, try using other supported browsers.

Also, if you still wish to contact our support, here's how to reach them:

1. In QBO, click the Help (question mark) icon at the upper right.
2. Select Contact Us at the bottom to connect with our live support.

Please know that I'm only a post away if you have any other issues or concerns. I'll be here to help. Have a good one!
