When a business engages a freelancer or contractor for a specific project, having clarity about what has been agreed — and documenting it properly — reduces the risk of disputes and helps establish the nature of the working relationship for tax purposes. A statement of work provides this clarity, and understanding what it is and what it should contain is useful for any founder regularly engaging external talent.

A statement of work — often abbreviated to SOW — defines the scope, deliverables, timeline, and commercial terms of a specific engagement. It typically covers what work will be done, what outputs will be produced, when they are due, how the contractor will be paid, and any relevant intellectual property or confidentiality provisions. A well-drafted SOW reduces ambiguity and provides a clear basis for resolving any disagreement about whether work has been completed to the required standard.

Beyond its commercial function, a statement of work that describes the engagement in terms of outputs and deliverables — rather than time attendance and direction by the client — is one of the factors supporting a genuine self-employment relationship. The document alone does not determine status, but it contributes to a pattern of evidence. Our guide to statements of work covers what to include and how to draft one effectively.
