I demo'd the invoice system this morning on the multisite to my co workers and the end client. They loved it, and it worked perfect. Installing this as the only plugin to have installed on a multisite template does the job quite superbly.
I was asked how the end user can export the invoices so that they can give these to their accountant. I couldn't seem to find a way to do this. Is this something that is in the system, but just cannot see where it is?
If not, is there a way to do this?
