A master services agreement, often called an MSA, is a long-form contract that sets out the governing terms between a service provider and a client across an ongoing commercial relationship. Rather than negotiating a new contract for every project, the parties sign one master services agreement that covers recurring legal and commercial terms, and then add individual engagements through additional Statements of Work. A master services agreement is widely used by software developers, content creators, marketing agencies, consultants, production companies, and other service providers who deliver work on a project-by-project basis.
Streamlining recurring engagements. A master services agreement reduces the friction of contracting for every new project. Once the master services agreement is signed, the parties can launch additional projects by signing a short statement of work that references the master services agreement, rather than renegotiating the full contract each time.
Separating legal terms from commercial scope. A master services agreement keeps the durable legal terms in one document and the project-specific commercial terms in another. This separation makes the commercial relationship easier to scale, because a statement of work can be drafted and signed quickly without reopening the negotiated legal terms of the master services agreement.
Allocating intellectual property clearly. Service-based work almost always produces intellectual property, whether source code, creative content, brand assets, or confidential information and data. A master services agreement defines who owns the deliverables, who retains background IP, and what licenses each party holds after the engagement ends.
Controlling risk across an ongoing relationship. A master services agreement allocates risk through limitation of liability clauses, indemnities, warranties, insurance requirements, and termination rights that apply consistently across every project. Without a master services agreement, each project may carry different and inconsistent risk allocations.
Supporting scope growth through statements of work. A well-drafted master services agreement anticipates that scope will grow. Statements of work can be added, amended, or layered on top of the master services agreement to expand the engagement, without disturbing the governing terms.
Sale of Goods Act, RSA 2000, c S-2. Alberta’s legislation governing contracts for the sale of goods, which can overlap with service contracts where deliverables include tangible items and implied terms of quality or fitness may apply.
Copyright Act, RSC 1985, c C-42. Canada’s federal copyright legislation, which governs authorship and ownership of creative deliverables produced under a master services agreement and generally vests first ownership in the author absent a written assignment.
Trademarks Act, RSC 1985, c T-13. Canada’s federal trademarks legislation, which is relevant where a master services agreement involves the use, development, or licensing of brand assets.
Inconsistency between the master services agreement and a statement of work. One of the most frequent problems in master services agreement relationships is a statement of work that conflicts with the governing terms of the master services agreement. A well-drafted master services agreement includes an order-of-precedence clause that specifies whether the master services agreement or the statement of work controls when the two documents disagree, and which specific terms a statement of work may override.
Unclear ownership of intellectual property. Under the Copyright Act, copyright in a commissioned work generally vests in the author unless assigned in writing. A master services agreement that is silent or ambiguous on IP ownership can leave a client paying for deliverables it does not own. Disputes commonly arise over ownership of source code, design files, training data, pre-existing tools, and derivative works.
Scope creep and undocumented change orders. Scope disputes are a leading source of litigation in service relationships. A master services agreement is generally drafted so that any expansion of the original scope is documented through a written change order or a new statement of work. Undocumented scope changes can leave the service provider underpaid and the client exposed to unexpected fees.
Limitation of liability and indemnity misalignment. A master services agreement allocates risk through caps on liability, exclusions of consequential damages, and indemnities for third-party claims. Issues arise where the cap is disproportionate to the value of the engagement, where indemnities are one-sided, or where statements of work attempt to carve out exceptions that were not contemplated in the master services agreement.
Termination and transition. Disputes over termination often turn on whether a party terminated a single statement of work or the entire master services agreement, what notice was required, and what obligations survive. A master services agreement generally addresses termination rights, wind-down of active statements of work, return of materials, and continuing obligations such as confidentiality.
What is the difference between a master services agreement and a statement of work? A master services agreement sets out the governing legal terms of an ongoing relationship, while a statement of work describes the specific scope, deliverables, timeline, and fees for a single project. Each statement of work incorporates the master services agreement by reference.
Do I need a master services agreement if I only have one project? A master services agreement is most useful where repeat engagements are anticipated. For a single, one-off project, a standalone services agreement may be more appropriate. A master services agreement can still be used for a single project if future work is expected.
Who owns the deliverables produced under a master services agreement? Ownership depends on the terms of the master services agreement. Without a written assignment, the Copyright Act generally vests copyright in the author. A master services agreement can assign deliverables to the client, retain ownership with the service provider subject to a license, or allocate ownership on a deliverable-by-deliverable basis.
Can a statement of work change the terms of the master services agreement? A statement of work can amend the master services agreement only if the master services agreement expressly permits it. An order-of-precedence clause typically controls which document prevails in the event of conflict and which terms a statement of work may modify.
Does a master services agreement need to be signed before every statement of work? The master services agreement is generally signed once at the beginning of the relationship. Each subsequent statement of work is signed on its own and references the master services agreement, rather than restating its terms.
