You've got me here to assist you with any QuickBooks concern, @kadabhilash.

Good to hear that you already know how to turn the Project into QuickBooks Online (QBO). I'm here to ensure that you can activate the feature so you can use it swiftly. 

Missing buttons in QBO are usually the result of outdated or corrupt cache files in your web browser. To get rid of the problem, I'd recommend doing some basic troubleshooting steps. To start, you'll want to log in to your account through incognito. This way, you can check if it's a browser-related issue. Here are the keyboard shortcuts:

• Ctrl + Shift + N (Google Chrome)
• Ctrl + Shift + P (Firefox)
• Control + Option + P (Safari)
• Ctrl + Shift + P (Microsoft Edge)

From there, go back to the Advanced page to verify if it's already operating adequately. If that goes well, you'll need to clear the cache of your regular browser to clear out the previously stored browsing data. Using another supported browser is a great choice too.

If the issue keeps going, I'd advise contacting our technical support. They can review your account and can send a ticket to our engineers for further investigation. 

Here's how: 

1. Go to the Help menu, then click Contact Us. 
2. Type your concern in the box and tap Let's talk. 
3. Click Chat and complete the required information. 

Ensure to call them within support hours to guarantee we can cater to your concern promptly.

Once everything is in place, you can now add projects and specific transactions. Then run the Profitability report to track all the data you've entered into the system.
