Reseller
termnetworkingvendors & products
The company that sells and installs somebody else's products for the organisation that will run them; also called a value-added reseller or integrator.
Their skill is not the products - it is making a portfolio assembled for commercial reasons behave like a system. A reseller arrives at an estate somebody else designed, with vendors who each assume they are the only one present, and has to produce something coherent from parts that were never tested together. That is a real discipline and it is largely undocumented, because every vendor's material describes a world containing only that vendor.
