What is the Difference Between MTS and MTO?
Inventory planning and decoupling point placement are critical for multi-product and multi-stage manufacturing operations. Choosing between Make to Stock (MTS) and Make to Order (MTO) dictates your working capital requirements, lead times, and operational flexibility.
Make to Stock (MTS) vs. Make to Order (MTO): Comparison
Primary Trigger: MTS uses Demand Forecast (Push System) | MTO uses Firm Customer Order (Pull System)
Lead Time: MTS is Very Short (Off-the-shelf) | MTO is Longer (Production + Delivery)
Inventory Risk: MTS is High (Risk of obsolescence/holding costs) | MTO is Low (Raw material & WIP focus)
Product Customization: MTS is Low (Standardized SKUs) | MTO is High (Tailored/Configured SKUs)
Ideal For: MTS suits High-velocity FMCG & Commodity goods | MTO suits Custom machinery & Project-based B2B
1. Make to Stock (MTS): Demand-Driven Buffer
The Make to Stock approach relies on accurate demand forecasting. Production runs ahead of demand to ensure finished goods are available across distribution networks.
Best For: Fast-moving Stock-Keeping Units (SKUs) and commodity goods (e.g., FMCG, packaging stock).
Key Advantage: Maximizes service levels by eliminating production lead time for the end buyer.
Main Risk: Trapped working capital and excess inventory carrying costs if forecasts fail.
2. Make to Order (MTO): Pull-Based Precision
The Make to Order strategy activates production only when a confirmed customer order is received.
Best For: High-mix/low-volume products, industrial equipment, and specialized B2B manufacturing.
Key Advantage: Minimizes finished goods inventory and eliminates stock obsolescence risks.
Main Risk: Requires strict shop-floor scheduling and optimized setup times to meet expected lead times.
The Hybrid Approach: Finding the Decoupling Point
Modern supply chains rarely rely 100% on pure MTS or pure MTO. Instead, top-performing plants utilize a Hybrid (Assemble to Order / ATO) framework, strategically placing the order decoupling point at the sub-assembly or raw material level.
To optimize your decoupling point, coordinate three core operational roles:
Inventory Planner: Classifies SKUs by cash velocity using ABC/XYZ analysis.
Production Planner: Balances line capacity between MTS buffers and MTO rush orders.
Fulfillment Planner: Aligns logistics scheduling with customer Service Level Agreements (SLAs).
