What Is a Statement of Work?
A statement of work (SOW) is a document that defines the deliverables, scope, timeline, and acceptance criteria for a project. It is often attached to a contract and turns a high-level agreement into an actionable plan. For a formal definition, see the reference entry on the statement of work.
SOW vs Proposal: What's the Difference?
A proposal persuades a client to hire you; an SOW documents what you will actually deliver once they say yes. The proposal sells the vision, and the SOW nails down the specifics both parties will be held to.
Essential SOW Sections
- Objectives — the business goal the project serves.
- Scope — what is included and, crucially, what is excluded.
- Deliverables — tangible outputs with formats and quantities.
- Timeline and milestones — phased dates and dependencies.
- Acceptance criteria — how "done" is defined and approved.
- Payment schedule — tied to milestones where possible.
Acceptance Criteria Prevent Disputes
