Thanks for visiting the Community, Harikrishna. Let me share information about customizing your sidebar menu in QuickBooks Online.

The left pane contains the different sections of features in QuickBooks. Personalizing them according to your preferences is currently unavailable. I can see the importance of adding a hyperlink button in the menu. With that, I suggest sending feedback to our product developers so they can review it and might consider adding this to our future updates.

Here's how:

1. Go to the Gear icon.
2. Under Profile, select Feedback.
   
3. Enter your suggestion.
4. Hit Next.

Additionally, you can change your view by clicking the Switch to Business view from the Gear icon.


 

I’ve added this link in case you need help navigating within QuickBooks. It includes all the features such as banking, reports and accounting, taxes, etc.

If you need further assistance with customizing QuickBooks, please feel free to let me know. I'd be glad to help you. Have a nice day.
