What is a Statement of Work (SOW)?

A Statement of Work (SOW) is a document that defines the scope of a project: what you will deliver, when, and often under what terms. It protects both you and the client by putting the agreement in writing—and it’s one of the best ways to prevent scope creep.

Why use a SOW?

Without a SOW, “scope” is vague. Clients may assume more is included; you may assume less. A SOW lists deliverables, milestones, and sometimes what’s explicitly out of scope. When a new request comes in, you can point to the SOW and either say “that’s covered” or “that’s a change—here’s the process and cost.”

What to include in a SOW

  • Project objectives and deliverables
  • Timeline and milestones
  • What’s in scope and (optionally) out of scope
  • Assumptions and dependencies
  • Revision/change process (how extras are approved and billed)

SOW vs contract

A contract is the legal agreement (payment terms, liability, etc.). A SOW is the project-specific scope. Often they’re used together: the contract says “we’ll do work as defined in SOWs,” and each project or phase has its own SOW that you and the client sign off on.

How ApproveDeck uses your SOW

In ApproveDeck you can upload or define your SOW per project. Our AI uses it to compare incoming client requests (from Slack, email, or project tools). When something looks out of scope, we flag it so you can turn it into a change request and bill for it instead of doing it for free.
