The supply chain strategy that produces goods only after receiving a customer order is make-to-order (MTO).
Make-to-order reverses the usual forecast-first sequence: a confirmed order triggers production, rather than finished goods being manufactured in advance for warehouse stock. This approach is common for customized, expensive, or relatively low-volume products, including made-to-measure furniture, specialized machinery, and some vehicles.
MTO is often confused with assemble-to-order. In assemble-to-order, standard components are already in inventory and are combined after the customer chooses a configuration. Engineer-to-order goes further: the product’s design itself may begin or change after the order. By contrast, make-to-stock relies on forecasts and keeps finished products ready for immediate sale.
The main advantage of MTO is lower finished-goods inventory and less risk of unsold stock. The trade-off is a longer customer wait and greater dependence on reliable suppliers, production capacity, and accurate promised lead times. In practice, manufacturers may still stock raw materials or modules, so “made after order” does not always mean every physical part is purchased from scratch.
