A master services agreement (MSA) is the foundational contract between two business parties, with deal-specific terms layered on as statements of work (SOWs). The MSA covers payment terms, intellectual property ownership, confidentiality, liability limits, indemnification, and termination — once. Each new engagement then references the MSA and adds only the SOW-specific scope and price.
This structure saves negotiation time on subsequent deals. Modern MSAs use conditional clauses that adapt to jurisdiction (CA-specific, EU-specific, NY-specific), industry (HIPAA add-ons for healthcare, DPA for EU data subjects), and deal size.
