At the moment if you want to create a new invoice hen you just cretate a new order and send one out. Work 99% of the time. However, every so often you want to be able to sent out an additional invoice from the same order number. Maybe for some extra work and the client’s finance department wants it on a seperate invoice. It happens. So, we need to be able to create mutliple invoices on one order.
Also, we need to have a log in the charges section that tells us when the invoice was send and also a copy of that invoice. This should be qite easy as i belive this is already recorded in the order log. We just need to take the information our of there and put it in a table.
