Master Service Agreement Vs Professional Services Agreement

Master Service Agreement vs Professional Services Agreement: What’s the Difference?

As a business owner, you’re probably familiar with service agreements – legal documents that outline the terms and conditions of a business relationship between a vendor and a client. But have you ever heard of a Master Service Agreement (MSA) or a Professional Services Agreement (PSA)? These two contracts are often confused with each other, but they serve different purposes. In this article, we’ll take a closer look at MSAs and PSAs and help you understand the differences.

Master Service Agreement (MSA)

A Master Service Agreement (MSA) is a broad contract used by companies that engage in long-term relationships with vendors, suppliers, or service providers. It outlines the terms and conditions that will govern all future transactions between the two parties, such as payment terms, delivery schedules, and intellectual property rights. Instead of creating a new contract for each project, the MSA serves as a framework agreement that can be used for multiple projects.

The MSA establishes a foundation of trust between the two parties, which can reduce the time and effort required to negotiate and sign future contracts. It also saves money on legal expenses, since the MSA covers all the basic terms and conditions that will apply to all future agreements.

Professional Services Agreement (PSA)

A Professional Services Agreement (PSA), on the other hand, is a specific contract used between a service provider and a client for a single project or engagement. Unlike the MSA, the PSA is project-specific and outlines the scope of work, the deliverables, and the timeline. It also includes details on fees, payment terms, and any specific legal provisions.

The PSA comes into play when a client needs to enlist the services of a professional, such as a consultant, a lawyer, or an engineer. It outlines the specific services that will be provided and sets expectations for both parties.

Key Differences

The main differences between MSAs and PSAs are:

– Scope: MSAs are broader in scope and cover multiple projects, whereas PSAs are specific to a single project.

– Flexibility: MSAs are more flexible since they can be used for future projects, whereas PSAs are rigid in scope and cannot be used for anything other than the specific project outlined in the contract.

– Length: MSAs are longer and more detailed than PSAs, which are typically shorter and more concise.

– Negotiation: Since the MSA is a framework agreement, negotiation of terms is typically more extensive and time-consuming. PSAs are generally easier to negotiate since they are specific to a single project.


Both Master Service Agreements and Professional Services Agreements play important roles in business relationships. The MSA provides a foundation of trust and saves time and money on legal expenses, while the PSA outlines the specifics of a single project and sets expectations for both parties. Understanding the differences between these two types of contracts can help you choose the appropriate agreement to use in your business relationships.
