How to Write a Simple Job Agreement for Service Work (What to Put in It)

A customer likes your price and asks, “Can you send me something in writing?” If you do not have a document ready, one of two things usually happens. You spend your evening trying to build one from scratch, or you skip it, shake hands, and hope everyone remembers the same job. Some service pros even knock money off the price just to get started without the paperwork.

You do not need a lawyer-drafted contract for every gutter cleaning or bathroom repair. You need one simple written agreement you reuse on every job, with a few blanks you fill in. This guide covers what goes in it, what to leave out, and how to send it without slowing the job down. It applies whether you clean houses, paint, mow, haul junk, or do general repairs.

This is practical guidance, not legal advice. Rules for written contracts vary by state and by trade, and some states have specific requirements for home improvement work, such as including your license number or a cancellation notice. Check with your state’s licensing board or a local attorney, especially for larger jobs.

Why a one-page agreement beats a handshake

Most job disputes are not about honesty. They are about memory. You priced “paint the living room walls.” The customer remembers “paint the living room,” which in their mind included the trim and the ceiling. Without anything in writing, it is your word against theirs, and the easy way out is usually you doing extra work for free.

A short agreement fixes three things:

• Scope. Both of you sign off on the same job.
• Money. The price, the deposit, and when the rest is due are not up for debate later.
• Changes. There is already a rule for what happens when the customer asks for more.

It also makes you look more professional than the person who sent a price by text. Customers who are comparing quotes notice that.

What to put in a simple job agreement

Keep it to one or two pages. These are the sections that do the real work:

• Who and where. Your business name, phone, and email. The customer’s name, the job address, and the billing contact if it is different (property managers and landlords often have someone else paying the bills).
• Scope of work. What you will do, written as plain tasks. “Patch and paint two bedroom walls, two coats, customer-supplied color” is better than “paint bedrooms.”
• What is not included. This is the line that prevents most arguments. Trim, ceilings, moving furniture, haul-away, permits, repairs to anything you uncover. Write it down.
• Materials. Who buys them, whether they are included in the price, and how you bill extras.
• Price. A fixed price for the scope, or an hourly rate with an estimate. If it is an estimate, say how far it can move before you check with the customer.
• Deposit and payment terms. How much is due to book, when the balance is due, and how they can pay. How to take deposits covers how much to ask for.
• Changes. One sentence: any added work is priced and approved in writing (a text or email counts) before you do it.
• Schedule. A start date and a rough finish, plus what happens if weather or access delays the job.
• Cancellation. How much notice the customer has to give, and whether the deposit is refundable.
• Signatures and date. An e-signature or a written “approved” reply to your email is better than nothing. A signature is better still.

Add the clauses your trade needs

The core is the same for everyone. A few lines change by trade:

• Cleaning: condition surcharges, pet hair, what happens if you arrive and cannot get in, and a re-clean window if something was missed.
• Painting: number of coats, who picks and buys the paint, and how you handle surprises like peeling paint or water damage under the old finish.
• Lawn care and landscaping: service frequency, skipped visits for weather, and how the season ends. Plant warranties for installs.
• Junk removal and hauling: what you will not take, how extra loads are priced, and dump fees.
• Repairs and remodels: what happens when you open a wall and find rot, bad wiring, or other hidden damage.

If the customer is a landlord or property manager who will send you a steady stream of jobs, add a dollar amount you can spend without calling first, how each property gets invoiced, and who arranges tenant access. That turns one agreement into a master agreement that covers every future work order.

Example agreement (fill-in version)

Example only. Adjust the wording for your trade and your state.

• Job: Interior painting, 123 Example St.
• Scope: Patch nail holes and paint walls in two bedrooms and the hallway, two coats, customer-selected color.
• Not included: Ceilings, trim, doors, closets, drywall repair beyond small patches, moving large furniture.
• Price: $1,450 fixed, materials included.
• Deposit: $400 to book the date. Balance due on completion.
• Changes: Any work not listed above will be quoted and approved in writing before it starts.
• Schedule: Start Tuesday, estimated two days.
• Cancellation: 48 hours notice for a full deposit refund.

That fits on one page and covers nearly every argument a painting job can produce.

Make it fast enough that you actually use it

The agreement only helps if sending it takes minutes, not an evening. A few habits make that happen:

• Build the template once. Write your standard terms one time and reuse them. Each job only needs the scope, exclusions, price, and dates.
• Capture details on site. Take photos and a quick voice memo before you leave the driveway, so the scope you write tonight matches what you agreed to. On-site estimates walks through what to capture.
• Combine it with your estimate. For most small jobs, the estimate with your terms printed at the bottom is the agreement. The customer approves one document instead of two.
• Do not discount to skip the paperwork. If writing an agreement feels like it costs you 40% of the job, the problem is not the agreement, it is not having a template yet.

When the job changes

The “changes” line only works if you use it. When a customer asks for one more room, send a quick written price for the added work and get a yes before you start. How to handle change orders covers how to price and invoice them. And if a customer goes quiet after the job, a signed agreement is the first thing you will want in hand. What to do when a customer won’t pay lays out the steps.

The short version

Use one reusable, one-page agreement for every job. Spell out the scope, what is not included, the price, the deposit, payment terms, and how changes get approved. Add a few trade-specific lines, get a signature or written approval, and check your state’s rules for larger home improvement jobs.
