Sometimes this means selling and marketing the product directly, but not all companies have the know-how or market presence to do it themselves, so they have to work with a distributor who has experience and foot in the target market. A distribution agreement defines the terms of an agreement between these two parties, which allows the distributor to sell and market the supplier`s products. A distribution contract can be international. The largest electronics and IT distributors, including Arrow Electronics, Avnet, Ingram Micro and Tech Data, operate subsidiaries in a number of countries for wide geographic coverage. Although there is no legal requirement for the agreement to be in writing, the Commercial Agent Regulations in 1993 provide that an agent has the right to request a written statement of the terms. To be enforceable, trade restriction clauses must also be in writing. g. Global Agreement. .
