Master Services Agreement (MSA)

A Master Services Agreement (MSA) is a standing contract between a services firm and a client that establishes the legal framework governing all future work, covering liability, IP ownership, payment terms, confidentiality, and dispute resolution. Individual projects are then executed under Statements of Work that sit beneath the MSA.

Negotiating the MSA once means neither party needs to relitigate legal terms on every engagement.

What an MSA covers

A well-drafted MSA addresses:

• Liability and indemnification (caps, carve-outs, mutual vs. one-way)
• Intellectual property (who owns custom deliverables, who retains pre-existing IP)
• Confidentiality and data protection (NDA terms, data handling obligations)
• Payment terms (net days, late fees, dispute resolution for invoices)
• Termination rights (for convenience, for cause, notice periods)
• Governing law and dispute resolution (jurisdiction, arbitration vs. litigation)

MSA vs. SOW

The MSA and SOW are complementary, not interchangeable.

	MSA	SOW
Scope	All work between two parties	One project or phase
Duration	Multi-year, until terminated	Project timeline
What it defines	Legal and commercial framework	Deliverables, timeline, price
Renegotiated	Rarely	Every engagement

The MSA handles the legal relationship. The SOW handles the commercial and delivery terms for a specific project. Running a project without an MSA means negotiating legal terms under time pressure every time.

Who drafts the MSA

Either party can originate the MSA. When the firm provides paper, it controls the default positions on liability caps, IP retention, and payment terms. When the client provides paper, the firm inherits the client’s preferred terms, which often include unlimited liability and client ownership of all work product. For enterprise clients with standard vendor agreements, it is common to negotiate specific carve-outs rather than replacing the document wholesale.

Common MSA mistakes

• Signing a client-paper MSA with unlimited liability without a full review
• No IP assignment clause, leaving ownership of deliverables ambiguous
• Payment terms that contradict the SOW payment schedule
• Missing a change-order framework that the SOW can reference
• No termination-for-convenience clause, which can trap the firm in an unprofitable engagement

A proposal is typically accepted before the MSA is finalized. Firms that start delivery before the MSA is executed take on significant legal exposure, particularly on IP ownership and termination rights. The MSA should be signed before any statement of work is countersigned.
