Why statement of work (SOW) matters to a first-time founder
A clear SOW turns a broad commercial promise into work that both sides can plan, price and accept. It reduces disputes about what is included, who does what and when payment is due. Missing assumptions or acceptance criteria can turn reasonable changes into delays, unpaid effort and damaged customer relationships.
Examples of statement of work (SOW)
A startup hires an agency to redesign its checkout for ₦30 million. The SOW lists five screens, two testing rounds, customer responsibilities, delivery dates and a requirement that agreed browser tests pass before acceptance. New analytics work must follow a written change process with its own price and timeline.
Common misunderstanding
It is not always the whole contract. A master services agreement may contain general legal terms, while each SOW defines a particular project. It also should not be a vague wish list: deliverables, exclusions, dependencies and acceptance should be specific enough for both parties to recognise completion.
When to use it
Use one before starting substantial client, supplier or contractor work with defined outputs. Agree scope, responsibilities, milestones, fees, expenses, acceptance, change control and termination effects. Check that it aligns with the main contract and seek legal advice where intellectual property, regulated work or cross-border obligations matter.
