Master Service Agreement (MSA)
A master service agreement establishes the legal and commercial framework that governs all projects and engagements with a given client or supplier.
What is a Master Service Agreement (MSA)?
A master service agreement (MSA) is a contract that establishes the general terms and conditions governing all current and future work between two parties. It covers the 'non-negotiable' commercial terms — payment, IP, confidentiality, liability, termination — so that individual project documents (statements of work, purchase orders) only need to address the project-specific details.
MSAs are particularly valuable for long-term, multi-project client relationships. Once signed, they reduce the friction of contracting for each new engagement, since parties only need to negotiate and sign project-specific documents rather than revisiting the full commercial terms every time.
When do you need a Master Service Agreement (MSA)?
- ✓When establishing a new client relationship that is expected to involve multiple projects
- ✓Before entering a significant supplier relationship for ongoing services
- ✓When an existing client relationship needs to be formalised under a single governing document
- ✓Before a large enterprise or government client will engage with your agency
- ✓As the precursor to any statement of work or purchase order
Key provisions to include
Scope Framework
How individual projects are scoped and governed under the MSA — typically via attached SOWs or purchase orders.
Payment & Invoicing
Standard payment terms, invoicing process, and late payment consequences.
IP Ownership
Default IP allocation for all work produced under the agreement, including background IP and new IP.
Confidentiality
Mutual confidentiality obligations covering all information shared under the agreement.
Warranties
Standard warranties about quality, originality, and non-infringement.
Liability Cap
Maximum liability of each party under the agreement.
Termination for Convenience
Right to terminate the entire agreement with reasonable notice.
Governing Law
Which state's laws govern the agreement and where disputes are resolved.
Common mistakes to avoid
Signing a client's MSA without reviewing the IP and liability provisions — client MSAs are often heavily skewed in the client's favour
Not including a clear order of precedence clause — defining whether the MSA or a specific SOW takes priority when they conflict
Having no automatic renewal clause — MSAs should be evergreen (automatically renewing) unless one party gives notice
Frequently asked questions
What is the difference between an MSA and a client service agreement?
They are functionally the same — both establish the general commercial terms for an ongoing service relationship. 'Master service agreement' is more commonly used in technology and enterprise contexts, while 'client service agreement' is more common in creative and marketing agencies. The substance is identical.
Does an MSA need to be renewed each year?
Not necessarily. MSAs are typically structured as evergreen documents — they continue indefinitely until terminated by one party. Individual projects are scoped and governed via SOWs or purchase orders, which have their own durations.
