Sometimes it’s advantageous to copy an existing invoice, rather than create a new invoice from scratch.  This is especially true for invoices that are repeated on a monthly basis.  To make the paperwork a bit easier, any invoice can be copied.  When an invoice is copied, a new invoice is created and automatically filled in with all the information of the invoice being copied. You can modify any fields which need adjustment if you desire. When the new invoice is saved for the first time, it will have a new invoice id and will be in the New state.

While reviewing an invoice, simply use the copy button and a new invoice will be created.

After you copy and optionally change the new invoice, don’t forget to save it!
