ODM is the abbreviation of Original Design Manufacture (Original Design Manufacturer). A product is designed and produced by one firm according to another firm's specifications and requirements. The entrusted party has the design ability and technical level, and produces products based on the authorized contract. For example, a computer company such as HP may specify specifications for a laptop computer it wants to bring to market. They will specify the appearance requirements of the product, such as the size and technical requirements of the screen, input/output ports, the forward tilt of the keyboard, the shape and color of the computer bag, the location of the speakers, etc. They also typically specify specifications for major internal details of the product, such as the CPU or video controller. However, they do not design drawings, specify the type of switching transistor used for the power supply, and do not select the frequency of the backlight converter. These are the jobs of ODM. ODMs design and manufacture laptops according to specifications put forth by computer companies. Sometimes, ODM can also be produced according to existing samples. The ODM method often pays more attention to cooperation, while in the case of OEM, the buyer basically does not participate in the specific specifications of the product.

The main difference between OEM and ODM is that in the former, the entrusting party proposes a product design plan—no matter who completes the overall design—and the entrusted party shall not provide third parties with products using the design; They are all completed by the manufacturer themselves, and the OEM buys them after the product is formed. Whether the manufacturer can produce the same product for a third party depends on whether the OEM buys out the design. OEM products are tailor-made for brand manufacturers. After production, only the brand name can be used, and the manufacturer's own name must not be used for production. And ODM depends on whether the brand company has bought out the copyright of the product. If not, the manufacturer has the right to organize production by itself, as long as there is no corporate design identification. To put it bluntly, the difference between OEM and ODM is that the core of the product is who owns the intellectual property rights of the product. If the entrusting party owns the intellectual property rights of the product, it is OEM, which is commonly known as "OEM"; The overall design carried out is ODM, commonly known as "OEM".

In industrial society, OEM and ODM are commonplace. Because of considerations such as manufacturing cost, transportation convenience, and saving development time, well-known brand companies are generally willing to find other manufacturers for OEM or ODM. When looking for other companies for OEM or ODM, well-known brand companies also have to bear a lot of responsibilities. After all, the product is crowned with its own brand. If the product quality is not good, at least customers will come to complain, and at worst, it may go to court. Therefore, brand enterprises will definitely carry out strict quality control during commissioned processing. But after the foundry is over, the quality cannot be guaranteed. Therefore, when some merchants tell you that the manufacturer of a certain product is an OEM or ODM product of a certain big brand, never believe that its quality is equivalent to that brand. The only thing you can trust is that this manufacturer has a certain production capacity.
