Hello, arafa.ahmed.

I'd like to extend a helping hand in accessing your account. 

When you say you can't open your company, are you receiving any error messages when accessing it? I'd appreciate if you could shed some more details about this. 

In the meantime, let's do the following steps to access your account. You might've already done these, but I want to make sure we've exhausted all possible solutions. 

It's likely that a different login was used, so let's make sure to enter the correct credentials when logging in. Check your email inbox for the payment confirmation associated with your subscription. 

Did you encounter a specific error message instead? This is likely caused by a cache-related problem.

We can rule this out by using an incognito window. This is a good way to check for any cache-related problems since this window works independent from the regular browser. Here are the shortcut keys: 

• Google Chrome or Microsoft Edge: Press CTRL + Shift + N.
• Safari: Press Command + Shift + N.
• Mozilla Firefox: Shift + CTRL + P.

Log in to your correct account and see if you can access it properly. If you're able to do so, go back to the regular browser and clear the cache. This removes the webpage data that's causing the issue. Though, using another supported browser also works. 

If you still can't access it, we would want to get to the bottom of this. I see that you've already sent an email and initiated a chat with our support. So, we'll want to give the agents another shot at opening your company. 

We can use the same chat link or we could also reply to the last email sent by our support regarding your account. 

If you don't have the chat link or can't reply to the email, let's use this link to chat with the agents: https://quickbooks.intuit.com/learn-support/en-global/contact.

After accessing your account, do you also need help accessing prior historical data in QuickBooks for your records? Check out this guide for more details: Enter historical information in QuickBooks Online.  

You can always post here if you have more questions about your data or QuickBooks Online. Let me also know if you have concerns entering some records or running reports. I'm here to help.
