The term "outside agencies" refers to organizations, groups or individuals that are not directly affiliated with a particular company, institution or government body. These entities may operate independently and can provide services, information or support to the entity they are associated with on an as-needed basis. Outside agencies can include anything from marketing firms, consultants, research organizations, suppliers, legal counsel, advertising agencies, among others. The relationship between outside agencies and their clients is typically governed by a contract that outlines the terms of service, expectations, and deliverables.
