New invoicing method when selling both goods and services

These costs must be invoiced at the same time as the products of the shipment.

This is the role of the invoice method to decide when a sale line must be invoiced. It is not difficult to say that a service must be invoiced once a shipment has been done.

@tbruyere

If I’ve tested it well, can’t we use this service-type product concept to put a charge on a sale?

For shipment cost it is better to use sale_shipment_cost because the invoicing of the cost is done automatically when the shipments are done.

@tbruyere

Example of costs: for certain product we must create product test certificates, this type is indeed a service. We have to include this service on the sale because we have to give a confirmation of sale with this service included.

Indeed it is if you need to track that the service has been actually delivered.
