A systems integrator is a company or individual that specializes in bringing together various subsystems or components into a cohesive, functioning whole, ensuring that these elements work together seamlessly within a larger system. This role is considered part of the [[physical channels|physical distribution channel]] because system integrators often handle the procurement, installation, and configuration of hardware and software components, physically assembling them to deliver a complete solution to the end-user. Unlike an [[original equipment manufacturer (OEM)]], which produces parts or equipment that may be marketed by another company under its brand, system integrators do not manufacture the components themselves but instead focus on combining existing products from multiple vendors to meet specific customer needs. While OEMs are primarily concerned with the production and branding of their products, system integrators add value through customization and integration services tailored to client requirements.
