Quick answer
An MSA is the master contract covering the relationship’s terms; an SOW is a per-project attachment defining specific work — MSA governs, SOWs specify.
MSA
Master Service Agreement — legal framework: liability, IP, payment terms, disputes; signed once, covers all work.

SOW
Statement of Work per engagement — scope, deliverables, dates, price for one project; attaches to the MSA.
The relationship
MSA = the constitution; SOWs = the individual laws — conflicts resolved per the MSA’s precedence clause.
Why the split
Legal terms negotiated once; work scoped per project — faster contracts for each new engagement.
