What would be the best way to do this, it seems that we were supposed to apply a discount to an invoice, but it didn't happen and its now posted. I have seen the option to remove sales history, but I'm not sure if this is the same as voiding or if the invoice will be deleted from the client's account.
What would be the best way to get around this situation where i need to apply a discount to a posted invoice?
Thanks,
