You can copy an existing customer invoice in two different ways:

1.  Directly from the customer invoice list:  Click on the “double sheet of paper icon” at the far right of the row.
   
   
   
   
2. If you click yourself into the detailed view of a customer invoice, you find Copy in the action bar at the bottom of your screen.
   
    

A pop up window will appear asking if you want to copy this invoice. Click on OK.

The new invoice is created identical to the one you copied, except for a new invoice number and today’s date. Make any necessary changes and click on Save or Post.
