Service Agreement vs Contract: What's the Difference?

The Short Answer

Every service agreement is a contract, but not every contract is a service agreement. A contract is any legally enforceable promise between parties; a service agreement is a specific type of contract that defines services, scope, and payment. For a plain-English primer, the legal library at Nolo's contracts encyclopedia is a helpful reference.

When to Use Each

• Service agreement — ongoing or project-based services: design, consulting, maintenance, marketing.
• General contract — sales of goods, partnerships, leases, or any binding exchange of value.

Key Clauses Both Should Contain

Clause	Why It Matters
Scope of work	Defines exactly what is delivered
Payment terms	Amount, schedule, and late fees
Term and termination	How the deal starts and ends
Intellectual property	Who owns the finished work
Liability and indemnity	Limits each party's risk

Protect Yourself With the Right Document

Do not rely on a verbal deal. Start from a vetted contract and agreement library and adapt it to your project. If confidentiality is involved, also read our NDA template guide.
