Statement of Work Template for SaaS Businesses (UK 2025)
Last updated: February 2025
Why SaaS Businesses Need a Statement of Work
SaaS statements of work define specific development projects, feature builds, or integration work within broader service or employment relationships. They must translate product requirements into precise technical specifications with measurable acceptance criteria, define deployment and testing procedures, and allocate responsibilities for bug fixes after delivery. The iterative nature of SaaS development means SOWs must accommodate agile methodologies while still providing contractual certainty on deliverables and timelines.
Key Clauses for SaaS
- Technical specifications with measurable acceptance criteria
- Sprint or milestone-based delivery schedule
- Testing, QA, and deployment procedures
- Post-delivery warranty and bug fix obligations
Common Mistakes
- Not defining acceptance criteria precisely enough, leading to disputes about whether deliverables meet requirements
- Failing to specify which party is responsible for testing environments, staging servers, and deployment infrastructure

FAQ
How should a SaaS SOW handle changing requirements during development?
Include a formal change request procedure that documents requirement changes, assesses their impact on timeline and budget, and requires written approval before implementation begins. For agile projects, define the process for re-prioritising the product backlog while maintaining the overall budget and timeline envelope, with any scope additions offset by scope reductions elsewhere.
What acceptance criteria should a SaaS statement of work include?
Define specific, measurable, and testable criteria for each deliverable. Include functional requirements with test cases, performance benchmarks such as response times and concurrent users, browser and device compatibility requirements, accessibility standards, and security requirements. Specify who performs acceptance testing, the testing period, and the process for reporting and resolving defects.
