A Statement of Work is a legally binding document that details exactly what a firm will deliver, when, and under what terms. It includes project objectives, deliverables, timeline, payment schedule, revision policies, and out-of-scope items. A clear SOW prevents misunderstandings and scope creep.

Why This Matters for Professional Services Firms
