We currently issue service invoices and product invoices which all go to the same sales code on the nominal ledger. We are looking to streamline this for more effective reporting and information by having the service invoice sales as a separate entity. In order to do this currently it can only be changed at the point the invoice is created manually on each line of the invoice. It would be really useful to set a default sales code to this invoice type so all totals were sent to that code.
