OEM vs ODM: What Is the Difference?

OEM vs ODM describes two ways a branded product can come to market. An original equipment manufacturer (OEM) defines the product, owns the design and sells it under its own name. It may build the product in its own factory or pay a contract manufacturer to build it, but the specification and intellectual property (IP) are its own.

An original design manufacturer (ODM) does the design work itself. It develops a product, often a whole family of them, and sells it to brands that put their own name, logo and sometimes a few changes on it. The ODM usually keeps the design and the IP, and the same base product can appear under several labels.

The terms cause confusion because OEM has drifted. It first meant the maker of a part used inside someone else’s product, which is why parts and software licences are still sold “OEM”. In industrial computing it now usually means the machine builder: the company that puts a computer inside its own kiosk, analyser, vehicle or control cabinet and sells the result under its own brand.

The table shows the usual pattern, not a rule. Every term here is set by contract, so an ODM can sell exclusive rights to a design, and an OEM can let its contract manufacturer keep the tooling. Read what the agreement says about IP, tooling and design files rather than relying on the label.

OEM and ODM sit among several related terms. Suppliers often use more than one to describe themselves, depending on the project.

Much of the world’s embedded hardware is designed and built by board makers in Taiwan and mainland China, and the same base design can appear under more than one brand. For an OEM building a machine, the choice is usually not “OEM or ODM” but how far to move away from a standard product.

Most projects stay with an off-the-shelf computer, configured, imaged and labelled for the application. The next step is semi-custom: an existing design with changed I/O, firmware, chassis branding or labelling. The last step is fully custom, such as COM Express carrier boards or NVIDIA Jetson carrier boards laid out around one product’s connectors and mechanics. Our system design and integration service covers all three, and reusing proven designs takes a signed specification to a verified custom prototype in typically 8–12 weeks.

Whichever model you choose, the risks sit in the contract and the paperwork. Under UK and EU product law, a company that places a product on the market under its own name or trade mark takes on the manufacturer’s legal duties, even if an ODM designed and built it. That brand must hold the technical file and sign the UKCA or CE Declaration of Conformity. In the USA, the responsible party for an FCC Supplier’s Declaration of Conformity must be based in the USA.

Before production, agree in writing who owns the design files and tooling, who controls the bill of materials (BOM), how changes are notified, and how long the product will be built. For industrial equipment that may be in service for 10 years or more, revision control and last-time-buy planning often matter as much as the build price.

We work with OEMs as an extension of their engineering team, supplying standard, branded and custom-designed systems with imaging, labelling and certification support as standard.
