Answer:
The lost opportunity cost of not ordering from a lower-cost supplier
Explanation:
Order cost can be defined as cost incurred when we create and processing an order to a supplier. It is included in economic order quantity for an inventory item. For example cost of labour that will inspect goods, cost of preparing a purchase order, and so on.
The opportunity cost of not ordering from a least cost supplier is not considered ordering cost as it represents a cost we did not incur.
