Yes, you can send an invoice to multiple recipients. You can add two emails to an invoice or copy the invoice. Let me show you how.
You can send an invoice to more than one customer by adding their email addresses and separate it with a comma. For example, enter "ppp@intuit.com,yyy@intuit.com".
To add multiple recipients:
Go to Invoicing menu.
Select the Invoices tab.
Locate the invoice you want to send. In the Action column, select Send from the drop down menu.
Enter the recipients' email addresses in the To field. You can also use the Cc and Bcc field.
Alternately, here's how to copy:
Open the invoice.
Click More.
Select Copy.
Enter the name of recipients in the Customer fields.
