Make-to-stock is a store at the level of the end product. Delivery takes place from the end products store according to customer order.
An order picking store or a commissary are special cases in the logistics flow that represent a status between actual stocking and use. Here all items or products are brought together that will be used for a certain production or sales order. They are stocked until final use in production or in the form of delivery to the customer. See Section 14.4.1.
