What Is a Service Agreement?
A service agreement is a contract between a business and its clients or suppliers that sets out the terms on which services will be provided, paid for, and resolved if something goes wrong.
Key Takeaways
- A service agreement defines scope, price, payment terms, liability, and dispute resolution.
- Without a written contract, disputes are governed by implied terms — which may not favour you.
- Limitation of liability clauses cap your exposure but must be reasonable to be enforceable.
- Your standard terms should be incorporated into contracts clearly before work begins.
What a service agreement covers
A service agreement (sometimes called a contract for services, a client agreement, or terms of business) is a legally binding document that sets out the commercial and legal terms on which your business provides services. The core provisions include: scope of services (what you will and will not do), fees and payment terms (amount, invoice schedule, what triggers payment), timescales and deliverables, intellectual property ownership (who owns what is created), confidentiality obligations, termination rights (what allows either party to end the agreement early), and liability — what happens if something goes wrong. Without a written agreement, disputes between you and a client or supplier will be resolved by reference to implied contractual terms and the general law of contract, which may not reflect the arrangement you thought you had.
Scope and change control
Scope creep — where a client gradually expands what they expect from a fixed-fee engagement — is one of the most common and damaging commercial problems for service-based SMEs. A well-drafted service agreement addresses this directly: the scope of services should be defined in detail (often in a schedule or statement of work attached to the agreement), and the agreement should include a formal change control process requiring any changes to scope to be agreed in writing and priced separately before work begins. Without this, you may find yourself legally obliged to deliver more than you budgeted for. A simple clause stating that 'any changes to the services must be agreed in writing by both parties' can save significant disputes.
Limitation of liability
One of the most commercially significant clauses in any service agreement is the limitation of liability provision, which caps the amount one party can claim from the other if things go wrong. Without this clause, your business could theoretically face unlimited liability if a client suffers a large loss they attribute to your services. Limitation of liability clauses typically cap your liability at the value of the contract or the amount of your professional indemnity insurance. However, under the Unfair Contract Terms Act 1977, a limitation clause must be reasonable to be enforceable — a clause that limits your liability for death or personal injury caused by negligence is void under English law. Ensure your limitation clause is drafted by a solicitor who understands the legal requirements.
Incorporating your standard terms
If you use standard terms and conditions for all your client engagements, those terms are only legally effective if they are properly incorporated into the contract — that is, brought to the client's attention before the contract is formed. This typically means: including a link to your terms in your proposal or quotation, requiring the client to sign or click to accept the terms before work begins, and ensuring the terms are available and legible. The battle of forms is a common pitfall: if a client sends you their standard purchase order terms and you accept without objecting, their terms may govern the contract rather than yours. Establish a clear practice of agreeing terms before any work commences.
