In manufacturing and supply chain management, the make-to-order (MTO) and make-to-stock (MTS) processes are two fundamental production strategies. Each approach caters to different business needs and customer demands. Below, we’ll explore the key differences between MTO and MTS processes, their advantages, and when each is most appropriate.

1. Definition and Core Concept

Make-to-Order (MTO)

• Products are manufactured only after a customer places an order.
• Production begins once specifications and requirements are confirmed.
• Example industries: custom furniture, bespoke clothing, and aerospace manufacturing.

Make-to-Stock (MTS)

• Products are manufactured in anticipation of future demand.
• Finished goods are stored in inventory and are ready for immediate sale.
• Example industries: fast-moving consumer goods (FMCG), electronics, and automotive.

2. Process Workflow

MTO Workflow

1. Customer places an order.
2. Design and production planning are tailored to the order’s specifications.
3. Raw materials are procured (if not already in stock).
4. Manufacturing begins.
5. Product is delivered upon completion.

MTS Workflow

1. Demand forecasts are analyzed.
2. Products are manufactured based on these forecasts.
3. Finished goods are stored in inventory.
4. Customers purchase products from stock.

3. Key Characteristics

4. Advantages and Disadvantages

Make-to-Order (MTO)

Advantages:

• Reduced inventory costs.
• Ability to provide customized products.
• Minimizes risk of overproduction and obsolescence.

Disadvantages:

• Longer lead times can deter time-sensitive customers.
• Dependence on reliable suppliers for timely raw material procurement.
• Higher per-unit production cost due to smaller production batches.

Make-to-Stock (MTS)

Advantages:

• Faster order fulfillment due to pre-produced inventory.
• Economies of scale in production lower per-unit costs.
• Predictable production schedules.

Disadvantages:

• Higher inventory carrying costs.
• Risk of overproduction and inventory obsolescence.
• Limited ability to meet unique customer specifications.

5. When to Use Each Approach

Make-to-Order (MTO)

• Suitable for businesses offering highly customized or specialized products.
• Ideal when demand is unpredictable or varies significantly.
• Best for low-volume, high-value production.

Make-to-Stock (MTS)

• Appropriate for standardized products with consistent, predictable demand.
• Useful in high-volume production environments.
• Best for industries with short lead time expectations.

NEW in Odoo 18.0:

Make to Stock and Order - acts like Make to Stock (checking for existing Inventory) and then acts like Make to Order (when there is insufficient stock).

6. Hybrid Models: Combining MTO and MTS

In some cases, businesses adopt a hybrid strategy to balance the benefits of both approaches. For example:

• Assemble-to-Order (ATO): Components are manufactured and stocked, but final assembly occurs after an order is placed.
• Configure-to-Order (CTO): Standard modules are produced and stocked, with customization applied upon order.

Conclusion

Choosing between make-to-order and make-to-stock processes depends on factors like product type, customer expectations, demand variability, and production capacity. While MTO offers flexibility and customization, MTS provides efficiency and faster delivery. Understanding the strengths and limitations of each approach helps businesses align their production strategy with market demands and operational goals.
