Make-to-order (MTO) and make-to-stock (MTS) are the two core manufacturing strategies. The choice between them shapes your lead times, inventory costs, and delivery speed.
Make-to-order builds each item after a customer places an order, so production follows real demand. Make-to-stock builds to a forecast and holds finished goods ready to ship.
Pick the wrong strategy and you either keep customers waiting or tie up cash in stock that never sells. This article breaks down the key differences between MTO and MTS manufacturing. It covers the advantages and disadvantages of each, plus the factors that point to the right fit.
You will also see how manufacturers apply both approaches, backed by outside research and results from named Fishbowl customers. Use it to match your production strategy to your products, demand patterns, and delivery promises.
Key takeaways
- Make-to-order (MTO) manufactures each product after a customer orders it, which fits bespoke or highly customizable goods.
- Make-to-stock (MTS) manufactures to a demand forecast and holds finished inventory, which fits standardized products with predictable demand.
- MTO cuts inventory cost but adds lead time. MTS speeds delivery but carries forecast risk and holding costs.
- The right production strategy depends on product complexity, demand predictability, and how long customers will wait for delivery.
What is make-to-order production?
Make-to-order (MTO) production, also known as build-to-order (BTO), is a manufacturing strategy where production is driven by demand rather than forecasts. Production begins after customers place an order. Each product is crafted to that customer’s requested specifications, so MTO is best for businesses selling bespoke or highly customizable products.
Make-to-order example
Dell built its business on build-to-order (BTO) personal computers. A customer configures the processor, memory, storage, and other components online, and Dell assembles that machine only after the order is placed. This approach delivers two clear benefits:
- Optimal functionality for the customer: each PC is built to the buyer’s exact specifications, so they pay only for the configuration they need.
- Less finished-goods inventory for the manufacturer: Dell assembles after the sale, avoiding large stocks of pre-built machines that could become dead stock.
What are the advantages of make-to-order?
MTO carries several benefits for businesses that value customization and lean inventory.
1. Customization
MTO tailors each product to the individual customer, which boosts satisfaction, retention, and referrals. Demand for that personalization is real. Deloitte personalization research found that 80% of consumers prefer brands offering personalized experiences and spend 50% more with them.
2. Reduced inventory costs
Because production only starts after a sale, MTO avoids unsold stock, and goods rarely become dead stock. Producing to confirmed orders also saves on storage, handling, and production costs.
3. Minimized waste
MTO produces only what customers order, aligning output with actual demand and preventing overproduction.
4. Increased efficiency
Producing orders that are already sold reduces the inefficiencies of mass production, such as poor resource allocation and defective batches.
What are the disadvantages of make-to-order?
MTO also comes with trade-offs that affect speed, planning, and cost.
1. Longer lead times
Production starts only after an order arrives, so longer lead times are common. Designing, producing, and delivering a bespoke item can take weeks.
Still, customer patience is greater than many assume. McKinsey delivery research found that about 90% of consumers are willing to wait two or three days for delivery. More than 80% will still buy an item when delivery takes four to seven days, as long as it is free.
2. Irregular sales demand
Custom orders arrive less predictably, which creates inconsistent production schedules. Bursts of orders can be followed by slow periods, making it harder to stock raw materials and staff appropriately.
3. Higher production costs
Bespoke processes and materials cost more, and customization is difficult to automate when every unit is unique. That raises labor and overall production expense.
What is make-to-stock production?
Make-to-stock (MTS), also known as build-to-stock (BTS), is a manufacturing strategy that produces to forecasted demand and stores finished goods until they sell. It suits standardized products with predictable demand and enables quick delivery.
Example of make-to-stock
A breakfast-cereal producer is a clear MTS example. It forecasts how many boxes of each variety retailers will order and runs long production lines to fill that forecast. Finished cereal then ships from the warehouse as orders arrive.
Bulk production keeps the cost per box low and lends itself to heavy automation, which is practical because every box is identical.
What are the advantages of make-to-stock?
MTS offers benefits for companies serving steady, predictable demand.
1. Reduced customer wait times
Because products are built in advance, they are ready for immediate shipment, which shortens lead times. A winter-coat maker produces year-round so that safety stock is on hand for peak season, which prevents stockouts when demand spikes.
2. Optimized resource allocation
Producing in large batches lowers the cost per unit and supports greater automation across the line.
3. Simplified production planning
Demand forecasts drive the production plan, which makes resource allocation more efficient and predictable.
What are the disadvantages of make-to-stock?
MTS depends on accurate forecasting and carries inventory risk.
1. Forecast dependency
Accurate demand forecasting is critical to MTS. It is difficult for variable or seasonal items, where a miss can cause surplus or unmet demand.
Forecasting is growing more sophisticated. Gartner forecast predicts that 70% of large organizations will adopt AI-based forecasting to predict future demand by 2030.
2. Risk of excess inventory
Holding large amounts of stock raises the risk of excess or obsolete inventory. The financial losses hit hardest in fast-changing categories like fashion.
The scale of that waste is significant. IHL Group research found that global retail loses about $1.73 trillion a year to inventory distortion, combining overstocks and out-of-stocks.
3. Increased storage costs
Large inventories require warehousing, and the fixed and variable costs of holding stock add up over time.
Make-to-order vs. make-to-stock: what’s best for your business?
The table below summarizes how the two strategies compare across the factors that matter most.
| Aspect | MTO | MTS |
|---|---|---|
| Production timing | Begins after a customer order, allowing for customization | Based on forecasted demand, produced in advance |
| Customization | High customization, tailored to specific needs | Standardized products with minimal customization |
| Lead times | Longer due to production starting post-order | Shorter, with products ready for immediate shipment |
| Inventory management | Low inventory management costs because production aligns with actual demand | Requires large inventories and higher storage costs |
| Demand predictability | Suitable for unpredictable demand, reducing overproduction | Ideal for stable demand, requiring accurate forecasting |
How do you choose the best approach for your business?
Weigh these three factors to decide between the two strategies:
- Product complexity: Highly customized or configurable products lean toward make-to-order, while standardized products suit MTS.
- Demand variability: Unpredictable or seasonal demand favors make-to-order, and stable, forecastable demand favors MTS.
- Customer expectations: If buyers will wait for a tailored product, MTO fits; if they expect immediate availability, MTS fits.
How does Fishbowl support both make-to-order and make-to-stock operations?

Frequently asked questions about make-to-order and make-to-stock
What is the difference between make-to-order and make-to-stock?
Make-to-order (MTO) builds each product after a customer places an order, so production follows real demand and items can be customized. Make-to-stock (MTS) builds to a demand forecast and holds finished goods until they sell, which speeds delivery for standardized products. The core trade-off pits lead time and customization against forecast risk and holding cost.
Can one inventory or manufacturing system handle both MTO and MTS?
Yes, many manufacturers run MTO and MTS side by side, building standardized lines to forecast while taking custom orders as they come. A single system that tracks inventory, orders, and production in real time can manage both. Fishbowl handles bespoke and standardized production in one system, so counts and promise dates stay accurate across both workflows.
What is assemble-to-order (ATO) and how is it a hybrid of MTO and MTS?
Assemble-to-order (ATO) is a strategy where a manufacturer stocks standard components in advance, then assembles the finished product only after a customer orders. It borrows from MTS by pre-building parts to forecast and from MTO by finishing to each customer’s configuration. That hybrid delivers faster than pure MTO and allows more customization than pure MTS, which is why configurable products like personal computers use it.
What is a real example of each?
Dell is a classic make-to-order example, assembling each personal computer to the customer’s chosen configuration after the order is placed. A breakfast-cereal producer is a make-to-stock example, forecasting demand, running large batches, and shipping finished boxes as retailers order. The first approach avoids finished-goods inventory, while the second keeps products ready for immediate shipment.
How do you know when to switch from make-to-stock to make-to-order?
Consider shifting toward make-to-order when customers increasingly ask for customization, when demand becomes hard to forecast, or when excess inventory starts eating into margins. If you carry stock that does not sell, producing to confirmed orders can lower that risk. Many manufacturers do not switch fully; they add make-to-order lines alongside MTS to balance speed with flexibility.
