- Individual projects are added by statements of work that refer to the MSA.
- The clauses that cause the most negotiation are liability caps, indemnities, intellectual property, data protection and termination.

What an MSA is
A master service agreement is a contract that sets the standing terms for a continuing supplier relationship, so that each later project needs only a short order or statement of work.
The point is to settle the hard legal questions once. Who owns the work product? What happens if something goes wrong? How is confidential information handled? After that, new projects are quick. A ready-made template is on the site at MSA template. This page explains the clauses and where each side tends to push.
A retailer signs an MSA with a software consultancy covering confidentiality, intellectual property, liability and payment terms. Over two years the retailer adds nine SOWs, each two pages long, for different projects.
When one project goes wrong, the liability cap and the termination right in the MSA decide the outcome without a new negotiation.
Clauses and typical positions
| Clause | Buyer usually wants | Supplier usually wants |
|---|---|---|
| Liability | Higher cap, carve-outs for data breach and confidentiality | Cap at fees paid, exclude indirect loss |
| Indemnity | Broad cover for IP infringement and third-party claims | Narrow, with conditions and control of defence |
| Intellectual property | Ownership of deliverables | Keep tools and pre-existing materials |
| Payment terms | Longer terms, dispute rights | Shorter terms and late fees |
| Termination | Convenience termination, short notice | Notice and payment for work done |
| Data protection | Strict security and breach notice | Limits on liability for breaches |
| Insurance | Minimum cover levels | Cover that they already hold |

How it works with SOWs
- The MSA holds the legal terms. The statement of work holds the scope, price and timeline for one project.
- Each SOW states that it is governed by the MSA.
- An order of precedence clause says which document wins in a conflict. Most buyers prefer the MSA, unless the SOW expressly overrides a term.
- Changes to scope go through change orders. Changes to terms go through a contract amendment.
- The MSA versus SOW page shows the split in a table.
Mistakes
- Signing an MSA with no order of precedence.
- Liability cap lower than the cost of a realistic failure.
- No termination right for the buyer.
- Data protection terms copied from a different country.
- Letting SOWs quietly override MSA terms.
- Scope of services and how orders work are clear.
- Liability and indemnity are agreed.
- IP ownership is settled.
- Confidentiality and data protection fit the work.
- Termination rights are balanced.
- Order of precedence is stated.
- A lawyer has reviewed it.

Frequently asked questions
What is a master service agreement?
A contract that sets the standing legal terms for a supplier relationship, with individual projects added by SOWs.
What is the difference between an MSA and a SOW?
The MSA holds the legal terms. The SOW describes one project. See the comparison page.
Do I need an MSA for a one-off project?
Probably not. A single contract may be simpler. An MSA pays off when you expect repeat work.
Which document prevails if they conflict?
Whatever the order of precedence clause says. Many agreements make the MSA prevail unless a SOW expressly overrides it.
How long does an MSA last?
Commonly a fixed term of one to three years with renewal, or until terminated.
