The business wants to be able to include instruction manuals with outgoing shipments, but does not want this item to be entered in the item ledger or inventory.
The reason given is that they do not want this order line to appear on the customer's invoice, and that the system is set up to prevent 0 unit price items. The business does not want a cost added to the inventory for this.
Is there a way to include a consumable that can be added to a sales order, so that the warehouse shipment document will include a line for warehouse staff to pick the correct instruction manual for an order, without it being a part of inventory or appearing on invoices?
