Delivery Note instead of Invoice?

New user here. Just created and paid a PRO version and only to find out
that “Delivery Notes” is not available ?

Created an invoice and clicked on “Delivery Note” but it still indicates “INVOICE” on the left.
Shouldn’t it be DELIVERY NOTE instead ?


@david can you please advise?


Which design are you using? There should be a Delivery Note reference on that document.
