Hello there, sahil1.
A QuickBooks Online account is only intended for one company. If you have more than one, you can create another account.
Just a heads up, another account means you'll have a different subscription.
Once you have multiple subscriptions, you can easily keep track of your financial status by switching an account.
Also, for more resources in managing your QuickBooks account, you can check this reference: QuickBooks Articles page.
Don't hesitate to reach out to us again, or you can mention my name if you have concerns.
