Thanks for your reply. In the demo I looked at before buying there was a list of all generated invoices on the invoice page on the front end. I assumed that the “demo” login provided was like an admin log in which gave access to view all invoices at once. I noticed the demo on your site has now changed and no longer has this. I think it is an essential feature you should consider putting into the “Invoice add on” as most companies will need to view all invoices at once to process accounts etc. Is there a way I can do this with code? e.g. is invoices a custom post type. Or is there a loop I can use in a PHP page to generate a feed of all invoices?
