A service agreement, also known as a service level agreement, is an agreement between a company and a customer, regulating the company’s obligation to check and repair (maintain) equipment or deliver another service for an agreed price during a fixed period of time, at a specified level.
Much the same as a service agreement, a maintenance contracts are agreements under which a service provider agrees to perform maintenance services to the benefit of a consumer., usually on equipment the provider sold to the customer, i.e. a stove or fridge.
