Make To Order

Make-to-Order (MTO) is a production strategy where manufacturing begins only after a confirmed customer order is received. In a pull supply chain, finished-goods inventory stays minimal or zero. The sales order generates a production work order, and planning works backward from fulfillment through procurement, material release, and assembly to meet the committed ship date.

In practical operations, MTO converts order management into a project-like discipline. A sales order enters planning first, then Bill of Materials explosion, component reservations, and routings sequence production against real capacity and material availability. Warehouse teams focus less on finished-goods racks and more on controlled staging of order-specific raw materials, work-in-process, and kit-based issue. Every lot, serial, and bin status is tied to a customer order, so parts cannot be released prematurely and shortages surface before manufacturing starts. Because many MTO shops coordinate procurement across suppliers and facilities, receiving, inspection, and kitting often become bottlenecks when multiple custom orders arrive together. Production scheduling runs backward from committed ship dates using actual demand, not forecasts. Manufacturing, inspection, and shipment are executed only after the order triggers the process. This supports customization, reduces finished-goods storage cost, and lowers excess inventory risk.
