A Master Service Agreement, spelled out, should take precedence as it will outline the overall structure of the agreement between the company and the vendor. This agreement is key as it sets the stage for any additional specific contracts or project-based terms. This document is pivotal in managing the broad terms and conditions that will govern all other projects and their respective contracts. An Acceptable Use Policy is more focused on guiding how company resources are to be used by individuals and does not cover vendor-client contracts. An agreement specifying the Service Level, fully spelled out, defines specific performance and quality metrics for services provided and does not typically establish general relationship terms. A Business Partners Agreement outlines the partnership between two business entities, but it is not as comprehensive in scope for service agreements and operations as a Master Service Agreement.
