Make to Order (MTO) and Make to Stock (MTS)

Make to Order

Make to order production is a process in which a product is individually manufactured for a particular customer. Stock keeping is not usually carried out for products that are made to order. The primary benefits of this process are the ability to track the progress for the sales order and the flexibility to offer to the customer the products to meet their specific requirements. The benefit also lies in tracking the costs incurred in the servicing of the sales order in the manufacturing of the goods and the ability of arrive at a profitability of the sales order.

Make to Stock

In make to stock production scenario stock is produced independently of orders because you want to provide your customers immediately with goods from that stock later on. You might even want to produce goods without having sales orders, if you expect that there might be customer demand in the future. This means

that make to stock strategies can support a very close customer-vendor relationship because your objective here is to provide your customers with goods from your stock as quickly as possible
