I recently went to the new quickbooks online. How do I create a billing statement of open items to send to my customers like I used to do easily before?

From the Homepage screen

      Click “+” sign (top middle)
      Select “Statement” under Other header

    How to email statement to a customer?

        Select “Edit” under Delivery Method column
        Default could be “None” 
        Select “Email” from the pop up screen and follow the instructions
        Select “Create/Send Selected Statements” button
        It will send email and will end with “Statements Created” message report.
