I stumbled upon something that is missing.
Case: A user wants to pay by bank after delivery, by making money over to the shop bank account noted on the invoice that came with the received order.
Problem: the store owner information like store addresses, telephone/fax, bank account numbers / IBAN etc etc. Can not be entered anywhere into the backend. So its impossible to include them on a invoice.
There is also need to include/generate a invoice number besides the order number. And/or possibility to make a order number dynamic for example: year+ordernumber (20090001)
Since I am working on a printable order invoice extension I really need to include this kind of information on the invoice.
