Can an Invoice be Un-invoiced?
No!
When an order is Invoice many tasks happen in the back end and undoing them can be different depending on what else has happened.
This is particularly complicated when connected to Account software as in most cases we cannot undo what has happened in the external system.
The correct way to deal with this is to credit the invoice and re-enter the order.
