Statement of Work (SOW)
A document that defines the specific work, deliverables, timeline, and costs for a particular project or engagement under a broader agreement.
A Statement of Work (SOW) is a contract document that defines the specific work to be performed, the deliverables expected, the timeline for completion, and the associated costs for a particular project or engagement. SOWs are typically executed under a Master Service Agreement (MSA), which sets the overarching terms of the relationship, while the SOW governs the specifics of each individual project.
Why It Matters SOWs are among the most operationally important documents a business manages because they define exactly what a vendor or contractor is supposed to deliver and when. Without clear visibility into active SOWs across your vendor relationships, it is easy to lose track of deliverables, miss completion deadlines, or fail to hold vendors accountable to the scope of work they agreed to.
In Practice A company has an MSA with a software development agency covering the overall terms of their relationship. Each new project is governed by a separate SOW that defines the specific features to be built, the delivery timeline, and the payment schedule. When a project runs over scope, the legal team pulls the relevant SOW to confirm what was agreed and where the deviation occurred.
