Key takeaways
- An MSA holds the standing legal terms. A SOW holds the scope, deliverables, timeline and price for one project.
- Signing the MSA once lets you sign each SOW in days.
- State which document prevails in a conflict. The MSA usually does unless the SOW expressly overrides it.
- Changes in scope go in a change order. Changes in legal terms go in an amendment.

Clause-level detail is on the master service agreement page. SOW structure is on statement of work.
A bank signs an MSA with an analytics firm. Three SOWs follow: a data audit, a model build and a training programme. Each SOW is four pages. The MSA covers data protection and liability for all three.
In SOW 2 the parties agree that the bank owns the model code. The SOW says that this overrides the MSA IP clause for this deliverable only.
Order of precedence
A typical clause says: if there is a conflict, the MSA prevails over the SOW, unless the SOW expressly states that it overrides a specific MSA term. Agree the rule before the first conflict.

Frequently asked questions
What is the difference between an MSA and a SOW?
The MSA holds standing legal terms. The SOW defines one project.
Which prevails, the MSA or the SOW?
Whatever the precedence clause says. Commonly the MSA, unless the SOW expressly overrides.
Do I need both?
For repeat work yes. For a one-off job a single contract may do.
Can a SOW exist without an MSA?
Yes, but it would then need to contain the legal terms itself.
Who signs the SOW?
Authorised signatories from both sides, usually the same as for the MSA.
