## Meaning

A Statement of Work (SOW) is a formal document that outlines the specific tasks, deliverables, timeline, and budget for a project between a client and a vendor or team. It defines what work will be done and what the expectations are.

In tech companies and consulting, a Statement of Work is a critical contract document that sets clear boundaries and expectations for any project engagement. It typically includes the scope of work, deliverables, timeline, payment terms, and responsibilities of each party. SOWs are used when a company hires an external vendor, freelancer, or contractor, or when different departments need to formalize an internal project agreement. Having a clear SOW prevents misunderstandings and scope creep because everything is documented upfront. You will encounter SOWs frequently in client-facing roles, project management, and when working with external partners.

## When you hear it

Before we start the project, we need to finalize the SOW with the client.

## Examples

- **in a project kickoff meeting:** "Everyone should have reviewed the SOW by now so we can align on deliverables and timeline."
- **in a client email:** "I have attached the SOW for your review. Please let us know if any modifications are needed."
- **in a team standup:** "We can't start development until the SOW is finalized and signed by both parties."

## What native speakers say

- "Let's get the SOW signed off before we begin work."
- "The client has approved the SOW."
- "We need to update the SOW to reflect the new requirements."

## Common mistakes

- ✗ "We need to SOW this project before we begin." → ✓ "We need to finalize the SOW for this project before we begin." (SOW is a noun referring to the document itself, not a verb meaning to start or begin work.)
- ✗ "The SOW covers everything we will possibly do." → ✓ "The SOW covers the agreed scope of work to prevent scope creep." (A SOW should define specific deliverables and boundaries, not unlimited work.)
- ✗ "I am writing a SOW to describe my job role." → ✓ "I'm writing a job description to describe my job role." (SOWs are for project engagements with clients or vendors, not for regular employment roles.)

## Be careful

SOW is sometimes confused with similar project management terms like RFP or MSA. It is a noun, not typically used as a verb. Do not use when discussing actual seeds or gardening.

## Word forms

| Part of speech | Word | Example |
| --- | --- | --- |
