Scope of Work (SOW)
Agency glossary · Updated July 2026
Definition
A scope of work (SOW) is the section of a contract or proposal that spells out exactly what an agency will deliver: the specific tasks, deliverables, timeline, and what is explicitly excluded. A clear SOW is the main defence against scope creep and disputes.
Why it matters
Most client disputes and lost margin trace back to a vague scope. A precise SOW sets expectations, protects the fee, and gives you grounds to raise a change order when the client asks for more.
What to include
Deliverables, milestones and timeline, number of revisions, assumptions, and an explicit out-of-scope list.
