Parties
Full legal names and contact details for all parties to the agreement; include entity type where applicable.
A well-drafted proposal reduces ambiguity about scope, fees, deliverables, and timelines, and provides written authorization to begin work. It helps manage client expectations, supports collections, and documents consent to electronic processes where used.
Professionals who bill hourly or by project commonly use this document to collect client data and secure an advance retainer before starting work.
Use the signed proposal as the controlling engagement record; attach exhibits and statements of work as appendices for specificity.
