If you are considering choosing an OEM manufacturing service, keep reading. In this guide, we’ll explain some qualities to look for in a reputable OEM manufacturer.

We’ll give you pointers on comparing shortlisted suppliers to help you reach a final decision. Explore the entire article before you begin your OEM manufacturing search. 

What Is OEM Manufacturing?

OEM stands for Original Equipment Manufacturing. It refers to companies that supply parts or equipment for another business’s production line. That’s in contrast to one that provides a finished item to the general public.

OEM manufacturers are specialists. They focus on producing particular components.

Their priority is making products of the highest quality. It’s also about creating an efficient production with high output to meet changing customer demands. OEM manufacturers often have a strong partnership with customers.

These manufacturers can help optimize supply chains. And they can ensure the end products meet specific standards (like regulatory standards). Collaborating with the best OEM manufacturer can positively impact any business.

Begin by Assessing Your Needs

You need to narrow your options before you can find an OEM partner. That starts with an inward look at your business and what your company needs. Those requirements will be your focal point during your search.

It will ensure you prioritize the OEM partners that best match your specific demands. Those demands should align with your high-level business strategy. Here are three elements you should consider as part of your requirements phase.


Not all OEM manufacturers will offer the same volumes. You need to find the one best aligned with your forecast. Do you need specific units, one-time or recurring monthly orders?

To establish the answer, look at your coming year’s sales forecast and product development roadmap.

Product Specification

Some products are complex and need specialists with the right technology and know-how. You must get a firm understanding of your product’s uniqueness and what degree of customization you need.

Remember that a product’s uniqueness might not be in the design. It could be related to regulations and laws, like a specific safety feature.

Delivery Timescales

Delivery timescales from your OEM partner matter, so think about your timeline and what slack you have in that.

However, it’s essential to focus on what timescales you need to fulfill your production targets rather than other factors like geography and proximity of the OEM.

An overseas company with high, reliable output might give you better timescales than a local one that’s less efficient.

Technical Capabilities

OEM partners offer more than machinery. They come with cutting-edge technology, industry experience, and specialist expertise.

Many also have a solid commitment to innovation and product development. All this can support your business, so knowing what qualities to consider is essential.


The most modern, state-of-the-art equipment will help deliver the highest-quality products. Modern automated systems provide precision. They also produce output reliably and quickly.

It could help you meet some demanding timescales from your customers. Assess what equipment each OEM manufacturer has so you can compare and contrast.

Industry Experience

Having an OEM manufacturer who knows your industry can be an advantage. You’ll want to see evidence of past projects in a related field.

Knowing more about a potential supplier’s expertise and experience will also help you to gauge whether they are a good match for your niche.

Product Development

Manufacturing is constantly evolving. You’ll want a company committed to learning, innovation, and product development. You’ll find evidence of that through the processes and technology they offer.

Whether they provide proof of concepts for new designs will also help you answer this question. Don’t forget to assess their industry reputation. Talking to other customers can help you learn about that.

Checking Quality

Product excellence comes from high-quality manufacturing. You’ll need to dive deep into an OEM’s commitment to its quality assurance processes. Let’s look at some of the ways to do that.


Check what standards and certifications each OEM follows, like the ISO series. International standards are best. They must prove an ongoing commitment to rigorous quality checks as part of those standards.


The OEM’s quality control processes will be central to their ability to deliver to your standards. It must be meticulous and well-practiced. It should include stringent checks that cover the complete end-to-end manufacturing process.

Plus, their checks should be transparent. An OEM with high-quality processes will happily share their system with you.

Track Record

Quality standards are vital, but an OEM company must also show evidence it can deliver to those standards. A track record of quality is a must. Sample products are helpful here to assess quality levels.

Industry reputation and customer references will also help you shortlist the best companies from a quality standpoint.


You’ll need an OEM that can scale with your business. Moreover, an OEM that offers flexibility will be better positioned to respond to the changing demands of your business.

It means you can cater to future growth or peaks in sales more easily. Likewise, you can scale back if the market demand drops.


Does the OEM have the infrastructure to scale up to large volumes? You’ll want to ensure they don’t become a bottleneck for your operation. Check they have the equipment and resources to produce high-volume orders.

Design Changes

You may be in an innovative environment that demands regular product changes. If so, you’ll want an OEM to support this with flexible manufacturing.

Can they adapt their production to meet design changes? What sort of lead time will they need? These are questions to ask before choosing an OEM.

Market Fluctuation

Can the OEM business adjust to changing demands? That’s important if you operate in an industry with a fluctuating market.

For example, perhaps you are in a price-sensitive market that has lulls during recessions. You should consider these scenarios and whether the OEM can adapt and stay on board.


A strong partnership with your OEM will ensure you get the most out of the relationship.

That comes down to effective communication. Open dialogue will foster a trusting, long-standing partnership. It will also help you collaborate, solve problems and innovate.

Ease of Communication

Consider the ease of communication when putting together your shortlist for OEM manufacturers. Is it easy and comfortable to approach the supplier?

Are there any barriers that could make life difficult, such as a generic customer support address instead of a named contact? It’s always worth conversing with a potential OEM supplier about your communication expectations.

Communication Method

You must also have a communication method and frequency that works for your business. You might prefer meetings or prefer to get updates via email. You may like to have a named contact you can call directly.

Working with a company that aligns with your communication needs is essential. It will help you build a stronger, long-term relationship.


Find out how your shortlisted OEM companies address feedback or concerns. They must take a problem-solving approach and look at ways to improve quality and delivery.

Being open to feedback will demonstrate they are a learning and growing business.


You’ll want an OEM that can offer a logistics setup as efficient as their production capabilities. It gives you reliability with your supplier, improving lead times and product availability.

Here are some factors to consider when reviewing the logistics aspect of an OEM manufacturer.

Supply Chain

Look for a business that has robust integration with other suppliers and distributors. It will ensure a more seamless link, reducing potential bottlenecks.

If an OEM has a strong relationship with other businesses in your network, it will be a significant advantage to you.

Handling Disruption

Sometimes things can go wrong. Your OEM must have a plan of action for dealing with disruption. It’s worth asking whether they have a risk management plan.

Find out their backup options to ship products to you in case of an unexpected event. This question is also relevant when examining if your OEM can handle unexpected requests or orders from you.


Ask the OEM what secure storage they have on offer. That includes security when shipping a product to you. It’s vital for your business operations and may also be a compliance issue for your business.

Aside from security, you’ll want to ensure they have other best practices for storage, such as robust inventory management processes.

Financials and Costs

It’s essential to find a cost-competitive supplier. You should also check that you are working with a financially stable business. An economically robust company will likely support you as part of a long-lasting relationship.


You will need to understand the cost of the products and a breakdown of the unit price, setup, and other charges. A reputable OEM will be transparent about their pricing and provide a clear picture of any additional fees.

Financial Health

A long-standing company will signal a reliable one. Look for signs of financial stability, such as public records or company history. It will reassure you that you won’t have a supplier closing their business and disrupting your operations.

Long-Term Cost Savings

If you are looking for a long-term partnership, you could negotiate costs as part of your contract. That might include discounts or loyalty incentives once you order a certain number of units.

Getting this information upfront is helpful as it will help you compare the long-term costs of each OEM on your shortlist.


A first-class reputation is often the best marker for choosing an OEM. Reputation in manufacturing is hard won, and if a company comes with glowing references, take note.

It paints a picture of a reliable, competent, and professional business. Here are some ways to uncover the reputation of an OEM.

Case Studies

Some companies will provide a detailed look inside other client projects via a case study. It’s a helpful guide and will tell you about their processes and approach.

You can assess their strengths and weaknesses. A case study often includes a customer quote about their experience, so it’s worth looking for these.


Industry recognition in aspects like quality and innovation is another sign to look for when assessing reputation.

These awards are often highly competitive so that they will point to a company with a high degree of expertise and a commitment to excellence.

Handling Disputes

If you can, ask for some customer references. When speaking to past customers, find out how the company handled disputes.

Problems will always arise, but what’s most important is what a supplier does afterward to remedy the situation. You want to look for evidence of effective communication and problem-solving skills.

Post-Manufacturing Support

When the OEM has delivered the product, what happens next? That’s a question to ask when assessing your shortlist. Here are some things to note in your supplier search.

After-sales Service

You’ll have a product warranty, but you should examine other ways the OEM provides after-service support.

That might be after-sales communications, ongoing product development, or product manuals. This will provide a picture of which companies put customer satisfaction first.


If the relationship involves knowledge transfer, determine how the OEM handles this. Look at other ways they pass on information, like training manuals, guides, or online help.

Product Development

Finally, look at how the OEM approaches new product development. Do they have a process in place?

Do they offer proof of concepts for new product designs? Working with a business that can embrace new ideas and take an innovative approach is essential.
