When developing a hardware product, you need to make many important decisions. One of the biggest is whether to make or buy hardware components.
A custom component can give you more control. However, it can also increase development time and costs. On the other hand, an off-the-shelf component can speed up development. It may also reduce engineering effort.
So, how do you choose the right option?
The answer depends on your product requirements, budget, production volume, technical resources, and long-term goals. Therefore, you should evaluate both options before making a decision.
In this guide, we explain the make vs. buy hardware components decision and the key factors you should consider.
What Does Make vs. Buy Mean?
The make vs. buy decision involves choosing between developing a component yourself and purchasing an existing solution.
What Does “Make” Mean?
Making a component means designing and developing it specifically for your product.
Your team can handle the development internally. Alternatively, you can work with a hardware engineering partner.
For example, you may develop:
- Custom PCBs
- Power management circuits
- Sensor boards
- Control boards
- Custom enclosures
- Embedded hardware
- Specialized connectors
A custom solution provides greater control. However, it also requires engineering time, testing, and product validation.
What Does “Buy” Mean?
Buying means using an existing component from a manufacturer or supplier.
Common examples include:
- Microcontrollers
- Sensors
- Displays
- Batteries
- Connectors
- Memory chips
- Communication modules
- Power supplies
- Cables
Since these products already exist, your team can focus on integration. As a result, you may reduce development time and reach the market faster.
Why the Make vs. Buy Decision Matters
The component strategy you choose can affect the entire product lifecycle.
For instance, a low-cost component may appear attractive during the prototype stage. However, limited availability could create production problems later.
Similarly, a custom component may deliver better performance. Nevertheless, development and testing can require a larger investment.
Therefore, you should look beyond the initial price.
Consider these factors:
- Development cost
- Unit cost
- Engineering effort
- Time to market
- Product performance
- Production volume
- Supply chain stability
- Quality
- Certification
- Long-term support
Most importantly, compare the total value of each option. This approach can help you avoid expensive decisions later.
When Should You Make a Hardware Component?
Custom development can make sense when existing components cannot meet your requirements.
Several situations can justify the investment.
1. You Need Unique Performance
Sometimes, standard components do not provide the performance your product needs.
For example, your product may require:
- Higher efficiency
- Lower power consumption
- Smaller dimensions
- Higher processing performance
- Specialized communication
- Better thermal performance
- Greater reliability
In such cases, a custom component can provide more flexibility.
Moreover, you can optimize the design around your exact requirements.
2. The Component Is Critical to Your Product
Some components directly control your product’s main functionality.
For example, an industrial device may need a custom control board. A standard board may not provide the required features or performance.
In this situation, custom hardware can become a competitive advantage.
3. You Need Product Differentiation
Standard components are available to many companies. Therefore, they may not help your product stand out.
A custom design can provide unique functionality. It can also help you create a smaller, faster, or more efficient product.
For example, custom hardware may offer:
- Better performance
- Lower power consumption
- Smaller form factors
- Unique functionality
- Improved reliability
As a result, custom development can be valuable when hardware innovation is central to your product.
4. You Have the Required Expertise
Custom hardware development requires specialized knowledge.
Your team may need experience in:
- PCB design
- Embedded systems
- Power electronics
- Signal integrity
- Thermal design
- Hardware testing
- Firmware development
If these skills already exist within your company, making a component may be easier.
Otherwise, you may need an external engineering partner. That additional cost should also be part of your decision.
When Should You Buy Hardware Components?
Buying is often the better choice when an existing component meets your requirements.
It can reduce development work and simplify your product design.
1. The Component Is Standard
There is little value in designing something that already works well.
For example, you usually do not need to develop a custom resistor or standard USB connector.
Instead, you can purchase a proven component. Your engineering team can then focus on more important parts of the product.
2. You Need to Launch Quickly
Time to market matters in competitive hardware markets.
Custom development requires several stages. These may include design, prototyping, testing, validation, and revisions.
By comparison, an existing component may be ready for integration.
Therefore, buying can be the better choice when you have a tight launch schedule.
3. The Component Is Not a Competitive Advantage
Not every part of your product needs to be unique.
For example, standard connectors, capacitors, resistors, and memory components usually do not differentiate a product.
Buying these components allows your team to focus on areas that create greater value.
4. You Want to Reduce Development Costs
Custom development requires an upfront investment.
You may need to spend money on:
- Engineering
- Prototypes
- Testing
- Tooling
- Certification
- Design revisions
In contrast, buying an existing component can reduce many of these costs.
As a result, off-the-shelf components can be especially useful during early product development.
7 Factors to Consider Before You Decide
The make vs. buy hardware components decision involves more than comparing two prices.
Instead, evaluate the following factors.
1. Total Cost
Cost is usually one of the first considerations. However, the purchase price is only one part of the equation.
For a custom component, include:
- Engineering costs
- Prototyping
- Testing
- Tooling
- Certification
- Manufacturing setup
- Maintenance
For a purchased component, consider:
- Unit price
- Shipping
- Integration
- Supplier management
- Minimum order quantities
- Licensing
- Replacement costs
Therefore, calculate the total cost of ownership for both options.
2. Time to Market
Next, consider your launch schedule.
How quickly does the product need to reach customers?
Custom development can take months. It may also require several design iterations.
An existing component can often move through development faster. Consequently, buying may provide a major advantage when speed matters.
3. Production Volume
Production volume can change the economics of your decision.
For a small production run, buying may be more practical. At higher volumes, custom development may become more attractive.
For example:
| Production Stage | Common Approach |
|---|---|
| Prototype | Buy |
| Low volume | Buy |
| Medium volume | Compare both |
| High volume | Consider making |
| Very high volume | Custom development may be attractive |
These are general guidelines. Your actual break-even point will depend on engineering costs, tooling, unit pricing, and production requirements.
4. Customization Requirements
Determine how closely an existing component matches your product requirements.
Ask the following questions:
- Does it have the correct dimensions?
- Does it support the required voltage?
- Does it provide enough performance?
- Does it meet environmental requirements?
- Does it support the required interface?
- Does it meet certification requirements?
If the existing component meets your needs, buying may be more efficient.
However, a critical missing feature could justify custom development.
5. Supply Chain Risk
Supply chain stability is another important factor.
A component may be available today. Yet, its availability could change during the product lifecycle.
Before selecting a supplier, check:
- Lead times
- Product lifecycle
- End-of-life policies
- Manufacturer reputation
- Minimum order quantities
- Second-source availability
- Geographic supply risks
In addition, ask whether you can replace the component without redesigning the entire product.
This step can reduce future supply chain problems.
6. Quality and Reliability
Low cost should never come at the expense of product quality.
When evaluating a purchased component, review:
- Datasheet specifications
- Reliability information
- Manufacturer quality standards
- Certifications
- Testing requirements
- Warranty
- Field performance
For custom components, define testing requirements before production.
As a result, your team can identify design issues earlier and reduce product failures.
7. Intellectual Property
Intellectual property can also influence your decision.
If a component contains an important part of your product’s competitive advantage, custom development may provide greater control.
However, ownership must be clearly defined.
Your agreement should cover:
- Schematics
- PCB design files
- Firmware
- Source code
- Manufacturing files
- Design documentation
- Custom tooling
- Intellectual property rights
Clear ownership terms can prevent disputes during future development.
Make vs. Buy: A Simple Decision Framework
A structured process can make the decision easier.
Step 1: Check Existing Solutions
First, determine whether a reliable component already meets your requirements.
If it does, compare suppliers and pricing.
If it does not, consider a custom solution.
Step 2: Identify the Component’s Importance
Next, determine how important the component is to your product.
If it drives your product’s unique value, making it may be worthwhile.
If it performs a standard function, buying may be more efficient.
Step 3: Estimate Production Volume
Calculate your expected production volume.
Importantly, consider the entire product lifecycle. Do not base the decision only on your first production order.
Step 4: Compare Total Costs
Now, calculate the complete cost of both options.
Make Cost = Development + Prototyping + Testing + Tooling + Manufacturing
Buy Cost = Unit Price + Integration + Logistics + Supplier Costs
This comparison provides a more realistic view of the investment.
Step 5: Evaluate Supply Chain Risks
Next, check the availability of the purchased component.
Look at its expected lifecycle. Also, identify alternative suppliers where possible.
Step 6: Consider Long-Term Support
Finally, think about future product support.
Will the supplier continue supporting the component?
Can you source it for several years?
If the answer is uncertain, a custom solution or alternative component may reduce future risk.
Make vs. Buy Hardware Components: Comparison
| Factor | Make | Buy |
|---|---|---|
| Customization | High | Limited |
| Initial development cost | High | Low |
| Time to market | Longer | Faster |
| Engineering effort | High | Lower |
| Product differentiation | High | Limited |
| Technical control | High | Moderate |
| Supplier dependency | Lower | Higher |
| Development risk | Higher | Lower |
| Best for | Unique requirements | Standard requirements |
Overall, neither option is always better.
Instead, the right choice depends on your product strategy, technical requirements, and business goals.
What About a Hybrid Approach?
You do not have to make everything yourself.
Likewise, you do not have to buy every component.
A hybrid approach can provide a better balance between control, cost, and speed.
For example, your product could:
- Use a standard processor
- Buy communication modules
- Use a custom PCB
- Buy standard connectors
- Develop custom firmware
- Use an existing power-management IC
This strategy lets you customize the parts that matter most.
At the same time, you can use proven components for standard functions.
As a result, your team can reduce development time while maintaining product differentiation.
Common Make vs. Buy Mistakes
Choosing Only by Unit Price
A low-cost component can create expensive problems.
For instance, poor availability may cause production delays.
Therefore, always evaluate the total lifecycle cost.
Ignoring Component Availability
Do not assume that a component will remain available forever.
Instead, check its lifecycle status before committing to it.
Customizing Everything
Custom hardware is not automatically better.
Creating a custom solution for a simple requirement can waste engineering resources.
Therefore, use custom development only where it adds real value.
Ignoring Production Volume
A strategy that works for 1,000 units may not work for 1 million units.
For that reason, always consider expected production volume.
Thinking Only About the Prototype
A component may work perfectly during prototyping.
However, mass production introduces different requirements.
Therefore, evaluate sourcing, testing, manufacturing, and support before finalizing your component strategy.
Questions to Ask Before Choosing Make or Buy
Before making your decision, ask:
- Is there an existing component that meets our requirements?
- Is this component critical to our product?
- How much customization do we actually need?
- What is the total cost of making it?
- What is the total cost of buying it?
- What is our expected production volume?
- How quickly do we need to launch?
- How reliable is the supplier?
- How long will the component remain available?
- Is a second supplier available?
- Does the component meet certification requirements?
- Who owns the design and intellectual property?
- What happens if the component becomes obsolete?
- Can we replace the component easily?
- Will this decision remain practical as production increases?
These questions provide a clear starting point.
More importantly, they help your team identify risks before they become expensive problems.
Final Thoughts
The make vs buy hardware components decision is more than a simple price comparison.
It is a strategic product decision.
Buying can make sense when a reliable component already meets your requirements. It can reduce development time and help you launch faster.
Making can be better when you need unique performance or greater control. It can also create a strong competitive advantage.
In many cases, a hybrid strategy offers the best solution.
Therefore, evaluate each component based on cost, customization, production volume, time to market, quality, supply chain risk, and long-term support.
Ultimately, the goal is simple: make the components that create value and buy the components that already solve the problem.
