Sales Service Contract

What a service contract is

A service contract is the signed agreement that governs an ongoing or one-off engagement after a sale has closed. It records who the two parties are, exactly what services will be delivered, how much they cost, when payment is due, and what happens when things go right — or wrong. Where a proposal persuades and a quote prices, the service contract is the document both sides point to when there is a disagreement.

A good service contract does three jobs: it removes ambiguity about scope and money, it allocates risk fairly between the provider and the client, and it gives both sides a clean, predictable way to end the relationship.

This guide is educational, not legal advice. PropoDoc is not a law firm and does not provide legal services. Contract law differs by country, state, and industry, and a clause that protects you in one place may be unenforceable in another. Always have a qualified lawyer review a contract before you sign, send, or rely on it.

When you use one

You use a service contract once a deal is essentially agreed — after the discovery conversation, after the sales proposal has been accepted, and after any price quote has been confirmed. It is the step that turns "we'd like to work together" into a binding, written commitment.

A proposal sells the work and a statement of work defines the specific deliverables; the service contract wraps the legal and commercial terms around both. For long relationships with many separate projects, teams often sign one master agreement and attach a fresh SOW for each piece of work — but for a single engagement, one well-drafted service contract is usually enough.

Who uses one

Agencies, consultants, freelancers, managed-service providers, and B2B vendors all use service contracts to formalise paid work. The structure is consistent across industries — what changes is the detail in the scope, the service levels, and the liability terms, which is exactly where professional legal review matters most.

Key clauses a service contract should include

Treat the list below as a checklist of topics to discuss with your lawyer, not as finished wording.

• Parties — the full legal names and addresses of the provider and the client, and who is authorised to sign. Getting the legal entity right matters; "Acme" and "Acme Holdings Pty Ltd" are not the same defendant.
• Scope of services / SOW — what will be delivered, in concrete terms, plus what is explicitly out of scope. Vague scope is the single most common cause of disputes. Often this lives in an attached statement of work.
• Fees and payment — the price, the billing schedule (monthly, milestone, or fixed), accepted payment methods, invoice timing, late-payment interest, and who covers expenses and taxes.
• Term and renewal — when the contract starts, how long it runs, and whether it renews automatically. Auto-renewal and notice periods deserve special attention; people get trapped by clauses they skimmed.
• Service levels (SLAs) — measurable commitments such as uptime, response times, or turnaround, plus what happens (credits, remedies) if they are missed. Only promise what you can reliably measure.
• Intellectual property — who owns the work product, what background IP each side keeps, and what licence the client receives. Decide whether ownership transfers on full payment or stays with the provider.
• Confidentiality — how each side must protect the other's non-public information, and how long the obligation lasts after the engagement ends.
• Warranties — the limited promises the provider makes about the quality of the work, usually paired with a disclaimer of broader implied warranties.
• Liability and indemnity — the cap on each side's financial exposure and who covers third-party claims. These clauses move real money and risk, so they are the clauses you most need a lawyer to draft and check.
• Termination — how either side can end the agreement (for convenience, for cause, with notice), what is owed on exit, and which obligations survive termination.
• Boilerplate — governing law, dispute resolution, assignment, force majeure, and how the contract can be amended. "Boilerplate" sounds minor but decides which court hears a dispute and which law applies.

Common mistakes to avoid

• Copy-pasting a contract you found online and signing it without review. Templates are a starting point for a conversation with a lawyer, not a substitute for one.
• Leaving scope vague. "Ongoing marketing support" invites argument; "8 social posts and 2 blog articles per month" does not.
• Ignoring the renewal and notice terms until the renewal date arrives. Diarise them.
• Skipping the liability cap and indemnity clauses because they feel like legalese. They are the clauses that determine your worst-case exposure.
• No clear payment and late-fee terms, which makes chasing unpaid invoices harder than it needs to be.
• Forgetting which clauses survive termination (confidentiality, IP, accrued fees), leaving gaps the moment the relationship ends.

Get legal review before you use this

Everything in this cluster — the guide, the template, and the worked example — is provided for education and as a drafting starting point only. It is not legal advice, it does not create a lawyer-client relationship, and PropoDoc is not a law firm. Before you sign, send, or rely on any service contract, have a qualified lawyer in your jurisdiction review it against your specific situation, the applicable law, and your industry's requirements.
