Scope of Services
Describe added tasks in specific, measurable terms so deliverables and exclusions are clear and the parties share the same expectations.
A precise additional services contract reduces disputes by defining scope, timelines, compensation, and approval steps. It creates an auditable change record that supports invoicing, project management, and legal enforceability under applicable contract law.
Multiple stakeholders create and rely on additional services contracts, especially when project scope shifts or clients request extra tasks.
Ensure the person signing has authority to bind the party; see Who Has Authority to Sign for details.
