SOW template library
Statements of work that say exactly where the project ends.
16 agency SOW templates with counted deliverables, explicit exclusions, revision limits and a change control clause your PMs can cite without an argument.
Agency will migrate all store data.
RewriteAgency will migrate products, variants, customers and 24 months of orders up to the caps in this SOW. Reviews, blog posts and redirects are migrated as listed in Schedules B and C.
Recreate existing store functionality on Shopify.
RewriteReplace the 11 legacy features listed in Schedule C with the named apps. Features not listed are out of scope.

Library
Pick your discipline. Copy the clauses. Adapt the appendices.
Each template pairs ready-to-edit clause blocks with an ambiguity check: the vague phrases that cause most scope disputes, rewritten into language a client can sign and a PM can enforce.

Anatomy of a defensible SOW
Six clauses decide whether a request is a favor or a change order.
Every template in the library follows the same structure, so your team learns one pattern and applies it to every proposal.
§ 1
Deliverables
Counted, named outputs. Screens by name, pages by number, objects by table. If you cannot count it, a client can expand it.
- 2.1 Fourteen screens listed in Appendix A
- 2.2 Three notification types listed in Appendix B
- 2.3 Twenty-two REST endpoints listed in Appendix C
§ 2
Exclusions
The clause clients read least and agencies cite most. Name what the project is not.
§ 3
Revision limits
Rounds, who consolidates feedback and how long a round stays open.
§ 4
Acceptance
Measurable tests and an auto-acceptance window, so delivery has an end.
§ 5
Assumptions
Client dependencies with dates attached. Late inputs move the schedule day for day.
§ 6
Change control
Who asks, who estimates, who approves, and that no change work starts before approval.
Why it matters
Scope creep is the default, not the exception.
A clear SOW will not stop clients from asking for more, and it should not. Good clients have new ideas. What a clear SOW does is turn each new idea into a calm, documented decision instead of a negotiation in a Slack thread.
Then use the change order scripts- 52%
- of projects experienced scope creep, up from 43% five years earlier
- 82%
- of out-of-scope requests first appear in Slack or Teams, not tickets
