A Contractor Service Agreement is a binding agreement between an individual or business offering a service—the contractor—and the person or organization hiring them—the customer. This agreement sets forth the details of the project to be completed, such as the scope and cost of the job, how long it will take, and any other applicable conditions. It outlines the responsibilities of each party, describes the payment structure and establishes any legal rights and obligations related to the work being done. All in all, this contract helps ensure that both parties have a clear understanding of what is expected during the course of the project.
