How to Write a Simple Service Contract for Your Business

Working without a contract is like driving without a seatbelt — most of the time nothing happens. But when something does go wrong, you wish you had one. A simple, one-page contract covers the most common disputes before they start.
You don't need a lawyer to start. A clear, written agreement signed by both parties is legally binding even if it's not a formal legal document. Start with a template, customize it for your business, and use it on every job.
The 8 things every service contract needs
- Names and dates — Your full business name, the client's full name, and the date of the agreement.
- Scope of work — A specific description of exactly what you will do. Not "clean the house" but "clean all bathrooms, kitchen, living areas, and bedrooms. Does not include garage, basement, or exterior windows."
- Price — The exact amount. Include whether this is a flat fee, hourly rate, or per-unit price.
- Payment terms — When is payment due? Do you require a deposit? What's the late payment fee?
- Timeline — Start date, completion date, or scheduled recurring service dates.
- Change order process — How will additional work be requested, approved, and priced? Without this clause, every scope expansion becomes a dispute.
- Cancellation policy — How much notice does either party need to cancel? What happens to the deposit if they cancel last-minute?
- Signatures — Both parties sign and date. Digital signatures (via DocuSign, HelloSign, or even an email confirmation) are legally valid in most states.
Tip: Use a simple Google Doc or Word template. Send it via email, get a reply saying "I agree to the terms" or a digital signature. That's a binding contract.
What to add for specific industries
| Industry | Add to contract |
|---|---|
| Contractors | Lien waiver language, permit responsibilities, material supplier policy |
| Event pros (DJs, photographers) | Force majeure clause, substitute vendor policy, copyright language |
| Pet services | Emergency vet authorization, care standards, what happens if a pet escapes |
| Personal trainers | Liability waiver, health screening acknowledgment |
| Cleaning | Access policy, what to do if property is damaged, key handling procedures |
Avoid these contract mistakes: Vague scope language ("general cleaning"), no cancellation policy, no change order process, and no late payment fee. Each of these omissions creates the conditions for a dispute.
Bottom line: A one-page contract takes 15 minutes to create and saves you from most disputes, chargebacks, and client misunderstandings. Use it on every job, no exceptions.
