What is a scope of work?
A scope of work is the part of a project agreement that defines the work itself: the deliverables, quantities, what is included and excluded, assumptions and acceptance criteria.
Definition

Statement of work (SOW)
A detailed document that defines project scope, deliverables, timelines, milestones, and terms. A well-written SOW prevents scope creep and sets clear expectations for both agency and client.
Scope creep
The gradual expansion of project requirements beyond the original agreement, often without corresponding budget or timeline adjustments. Scope creep is one of the leading causes of project overruns and profit erosion.
Change order
A formal document that modifies the original project agreement when scope, timeline, or budget changes. Change orders protect agencies from scope creep by making scope changes visible and billable.
Deliverables
Tangible outputs or work products that agencies produce and deliver to clients. Clearly defining deliverables in scope documents prevents scope creep and ensures mutual understanding of project outputs.

Frequently asked questions
What should a scope of work include?
Deliverables with quantities and formats, included tasks, an explicit list of exclusions, assumptions about what the client provides, revision limits and acceptance criteria. Timeline and payment terms usually sit in the wider statement of work or contract.
What is the difference between a scope of work and a statement of work?
The scope of work describes the work itself: deliverables, inclusions, exclusions and acceptance. The statement of work is the complete document that includes the scope plus timeline, milestones, fees, payment terms, roles and the change process. Many people use "SOW" for both, so define the term in your own contracts.
How do I write exclusions in a scope of work?
List the tasks clients most often assume are included but are not: content creation, stock assets, third-party fees, hosting, migration, extra revision rounds, and work on other channels or pages. Be specific. "Copywriting is not included; the client supplies final copy" is clearer than "content not included".
When should you create a change order?
When a client asks for work outside the agreed scope. Describe the addition, estimate the extra cost and time, get written approval, and update the scope so it stays current.
