I want to send a copy invoice to another email account

Hi @lindak1119 

In Customer Information popup (at least when blank) it give you the option of adding multiple email addresses - separated by commas...

Hope that helps.

Hello Robert13, 

Welcome to the Community page, 

When you are on the invoice in the customer email box all you need to do is enter in a comma between each email address make sure there is not spaces either just email address comma email address and it will save and send for you with no issues.
