What does MSA stand for?
MSA stands for master services agreement, sometimes written as master service agreement. It is the top-level contract between a customer and a vendor that establishes the standing legal terms under which the vendor provides services. Specific purchases and quantities are documented separately in order forms or statements of work that reference the signed MSA.
What is the difference between an MSA and an SOW?
An MSA is the top-level framework contract that covers the legal terms of the relationship: IP, liability, warranty, indemnification, data, confidentiality, and termination. A statement of work (SOW) is a document under the MSA that describes a specific professional services engagement with its scope, deliverables, timeline, and price. The MSA is signed once; multiple SOWs can be signed under it.
What is the difference between an MSA and an order form?
An MSA holds the legal framework and does not contain prices or quantities. An order form is a short commercial document that captures a specific purchase: the products, seats, term, and price. The order form references the signed MSA and inherits all its legal terms. One MSA, many order forms, is the standard pattern in B2B SaaS.
What clauses are in a standard B2B SaaS MSA?
A typical B2B SaaS MSA covers the license grant, intellectual property ownership, limitation of liability, warranties and disclaimers, mutual indemnification, data processing and privacy, confidentiality, service levels, payment terms, termination rights, governing law, and the order of precedence between the master and its attachments. Pricing and quantities live in the order form, not the MSA.
How long does a master services agreement last?
Most MSAs have an indefinite or long term and stay in force as long as any order form under them is still active. The commercial terms live in the order forms, each of which has its own term (typically one or three years). Terminating the MSA generally terminates all live order forms; terminating a single order form does not touch the MSA.
Who signs an MSA first, the customer or the vendor?
Either party can send the first draft, but in B2B SaaS the vendor usually sends their standard MSA as the starting point. Enterprise buyers often insist on their own paper. In practice, the paper that wins is the paper of the party with more leverage, which is usually the buyer in a large deal. The MSA and the first order form are typically signed at the same time, on the same signature page.
Does the MSA replace the NDA?
Not exactly. An NDA (usually a mutual NDA) covers confidentiality during the pre-sale evaluation period. An MSA covers the full commercial and legal relationship after a purchase. Most MSAs include a confidentiality section that supersedes the earlier NDA for the covered relationship once the MSA is signed, but the NDA often remains useful for discussions that fall outside the MSA scope.
Can an MSA be amended after it is signed?
Yes. If a legal term in the MSA needs to change, the parties sign a formal amendment that is attached to the master. Amendments apply to all current and future order forms under the MSA. Signing a new order form never amends the master; the MSA can only be changed by amending it directly, which usually requires another round of legal review on both sides.
