Hello there, ysharat.

There are certain features that work in the US entity and not on your India entity. The option to merge two company data files into one company is currently unavailable in QuickBooks Online. Each company is created as a separate file and can't be merged. However, you can manually input the data into the company you want to keep. 

You can also import files and lists into the account you want to keep instead of manually entering them. For more details, use this reference: Common questions about importing data to QuickBooks Online.

Keep me posted if you have other questions. You take care and have a great day!
