Make-to-Order (MTO)
Make-to-Order (MTO), also called made-to-order or mass customization, is a production strategy in which goods are manufactured only after a confirmed customer order. Rather than building and storing finished products in advance, MTO is a pull-based approach that responds to actual customer demand and enables higher levels of customization.
Key takeaways
- Products are produced only after a customer places an order.
- MTO reduces finished-goods inventory, obsolescence, and waste.
- It enables customization but typically increases lead times and unit costs.
- Common in industries with high configuration needs or expensive inventory (aircraft, automotive, construction, computers, furniture, high-end fashion).
How MTO works (typical process)
- Customer places an order and configuration is confirmed.
- A bill of sale and internal work order are created.
- Required components are sourced (from stock or suppliers).
- Product is manufactured/assembled to specification.
- Quality checks are performed, then the product is shipped to the customer.
Advantages
- Customization: Products can match exact customer specifications, improving satisfaction and loyalty.
- Lower inventory costs: Fewer finished goods held in stock reduces holding costs and risk of obsolescence.
- Reduced waste: Materials and components are used only as needed.
- Full-price potential: Less need for discounting to clear excess inventory.
Disadvantages
- Longer lead times: Customers wait while items are produced and tested.
- Higher per-unit cost: Loss of economies of scale increases production cost for customized units.
- Supply-chain complexity: Timely sourcing of components is critical; disruptions can delay delivery.
- Not suitable for high-volume, low-cost everyday items.
MTO vs. MTS vs. ATO
- Make-to-Stock (MTS): Products are produced in advance and stocked for immediate sale. MTS supports fast delivery but risks excess inventory and obsolescence, especially in fast-changing markets.
- Assemble-to-Order (ATO): Components are pre-manufactured and stocked; final assembly occurs after order receipt. ATO shortens delivery time compared with MTO while still offering some customization.
- MTO: Best for highly customized, lower-volume, or expensive-to-hold products where full production after order is acceptable.
Industries that commonly use MTO
- Aerospace and defense
- Automotive (especially specialty or configurable models)
- Construction and real estate (custom homes)
- Computer hardware and servers (highly configured systems)
- Furniture and high-end fashion
- Specialty vehicles and e-bikes
Example: Custom electric bicycle
A customer configures an e-bike (frame type, motor size, battery capacity, color, accessories). No finished unit exists until payment and specifications are confirmed. The company sources or reserves components, assembles the bike to the selected options, performs electrical and safety tests, then ships directly to the customer—minimizing intermediary storage.

Implementing an MTO strategy
- Define configurable options and pricing models.
- Build a streamlined order-capture process (easy configurator and clear lead times).
- Establish reliable supplier relationships and component lead-time visibility.
- Implement production planning that prioritizes order-specific work orders.
- Communicate status to customers and manage expectations about delivery times.
- Use demand management and forecasting for components, not finished goods.
When to use MTO
Choose MTO when customers value customization, product variants are numerous, finished inventory is costly or risky to hold, and customers accept longer wait times. Avoid MTO for everyday commodities and when rapid delivery and low unit cost are the priority.
Bottom line
Make-to-Order is a pull-based production approach that trades speed and unit-cost advantages for flexibility and reduced inventory risk. It fits industries and products where customization and minimizing finished-goods stock outweigh the costs of longer lead times and more complex supply-chain coordination.
