Good question, abhinandan.

I'm here to give options on how  you can add an existing bills to an individual projects in QuickBooks Online (QBO).

You can either assign a customer name to the line item of your existing bills or make it billable to the project. 

1. Open your existing bill.
2. Assign a Customer/Project name or make it billable.
   
3. Click Save and close.
