An annual maintenance contract (AMC) is an agreement with a service provider for repair and maintenance of property used by your company. The service can be of any property owned by your company from the large manufacturing machines creating your products down to the computers and printers used in your offices. It can also include service to the building, the land, parking lots, etc. A company that cares about improving day to day operations should have an AMC in order to ensure quality of product and process.
