Thank you for posting here in Community, @lakshmanan-souda. Let me assist you with how you can add your companies with one user ID.

Here's how you can add two companies with one user ID:

1. Go to QuickBooks pricing page and select the subscription option you want.
2. If you're currently signed in to QuickBooks Online, you'll see a prompt to confirm the account you want to sign in. Select Yes, that's correct if this is true.
3. Otherwise, click the Sign In link to log in with your Intuit account.
   
4. Click One more step and it will create a new company file with the same user ID as you used.
