i just register a new company but my account is not signing in

Thanks for reaching out to the Community, @al raheel. I'm here to help ensure you can log in to QuickBooks Online.

May I know the specific issue you experience when logging into your account? Any additional information can help me provide a timely resolution. 

This issue usually happens if you're encountering bugs when trying to load a website. Clearing the cache in a browser helps fix this. Let's confirm first using your browser's private window. Here's how:

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

If you logged in successfully, we can clear the browser cache to get a clean slate for your browser. You can also switch to other browsers to see if the problem is with your current one. 

However, if you’re experiencing a different issue, check out the Get help if you can't sign in to your account guide. The troubleshooting is scenario-based, so I suggest following the steps that fit your situation. With these steps, you can correct your payroll and login into the account in no time.

Kindly post an update on how things go on your end. I want to make sure everything is all sorted out and I'll be right here if you need further assistance with your log in account in QuickBooks.
