It often sits alongside a broader services agreement that governs legal terms. ## Key takeaways - State what is included and excluded, who supplies inputs, how changes are approved and how deliverables are accepted. - A list of activities without a definition of completion can produce disputes even when both parties worked in good faith. - Use the definition consistently across your marketing, product and sales discussions. --- This concept sits within [saas marketing agencies](/saas-marketing-agencies/). Use the definition above to align terminology before comparing reports or planning work. ## A SaaS example A website project SOW lists page types, migration responsibilities, review rounds, accessibility requirements and launch acceptance checks. This is an illustrative scenario, not a reported result from a customer study. The point is to show the meaning of the term and the decision it affects. ## The mistake to avoid A list of activities without a definition of completion can produce disputes even when both parties worked in good faith. ## Put the definition to work State what is included and excluded, who supplies inputs, how changes are approved and how deliverables are accepted. When adding the term to a brief or dashboard, write down the scope and the evidence the team will use. Assign an owner for the definition so it does not change quietly between reporting periods. If two teams use the same label differently, resolve that difference before combining their numbers or handing work between them. ## Related reading - [B2B SaaS Marketing Agency](/guides/b2b-saas-marketing-agency-agencies/) - [SaaS Agency Engagement Models](/guides/saas-agency-engagement-models/) - [Choosing a SaaS Marketing Agency](/guides/how-to-choose-a-saas-marketing-agency/) - [SaaS Marketing Agency Pricing](/guides/saas-marketing-agency-pricing-agencies/) Browse the [full glossary](/glossary/) for adjacent definitions and the [resource library](/resources/) for working materials. {/* expanded-practice-2026-09 */} ## Apply statement of work in a working review Start by explaining the term without repeating its label. Then point to an observable example and a counterexample. If it is a metric, write the unit, numerator, denominator and time window. If it is a role, process or strategy, identify the responsibility or decision that distinguishes it from adjacent terms. This prevents a shared word from concealing different operating assumptions. For this topic, involve the client owner and agency delivery lead and work from agreed scope, acceptance criteria and account ownership inventory. The relevant unit is a comparable deliverable or operating outcome. State the question the review should resolve before choosing a chart, an asset or a tool. If participants disagree about the unit or scope, resolve that disagreement before combining their evidence. ### Evidence to prepare Compare the actual work, internal effort and delivery dependencies rather than the retainer alone. Keep reporting definitions and asset ownership clear enough that the client can inspect the work and continue operating after the engagement changes. | Review field | What to record | | --- | --- | | Topic | Statement of work | | Decision | The specific action this explanation should help you choose | | Working evidence | agreed scope, acceptance criteria and account ownership inventory | | Unit and scope | a comparable deliverable or operating outcome | | Responsible people | client owner and agency delivery lead | | Remaining uncertainty | The missing fact that could change the decision | ### Two situations that can change the interpretation #### When an agency scope has no acceptance criteria A landing page can be delivered as a file while still failing the agreed mobile, tracking or content requirements. Use this check: Choose one promised deliverable and identify the observable requirements, review owner and allowed revisions. Do not treat an internal project note as a substitute for appropriate commercial review. The [focused diagnostic guide](/guides/agency-scope-has-no-acceptance-criteria/) provides the correction process and a working evidence sheet. #### When an agency trial has no end decision A test project should reveal whether the working method fits, not simply postpone the decision through another vague extension. Use this check: Review the trial's question, deliverables, acceptance criteria and decision date. Do not use a trial to extract unagreed unpaid work or avoid legitimate payment obligations. The [focused diagnostic guide](/guides/agency-test-has-no-transition-plan/) provides the correction process and a working evidence sheet. ### Record the decision and the limit An agency can complete a draft while the deliverable remains blocked on an agreed technical review. That is different from failing to produce the draft. A useful scope distinguishes responsibilities and acceptance criteria so the relationship can address the real bottleneck. Keep the conclusion beside the evidence that supports it. Record what the team will do, who owns the next action and which event or date will trigger a review. If the underlying definition, audience or product behavior changes, revisit the conclusion rather than assuming the old result still applies. A clear limit is useful information; it tells the next reader where additional investigation is required.
