Seven Clauses on a Single Sheet: The Short Agreement That Survives a Real Dispute

The received wisdom about contracts in a small business is that a proper one requires an attorney, costs more than the job is worth, and would insult the customer if produced, which is why an enormous amount of work is done on an email and a handshake. The premise is wrong at both ends. The disputes that actually destroy small jobs turn on a handful of terms that any competent person can write in plain sentences, and a customer who reads a clear one-page agreement almost never reacts badly, because what it mostly communicates is that somebody has done this before.

Who the Parties Are, and What Is Actually Being Bought

Start with names, and use legal ones. The full legal name of the business, including its designator, and the full name of the customer, along with the address where the work happens if that differs from the billing address. This sounds trivial and it is the first thing to fail: an agreement naming a trading name that is not a legal entity, or naming one spouse where two own the property, produces a document that is awkward to enforce against anybody. Include a phone number and an email for each side, since that is where notice will eventually be sent.

Then describe the work, and describe it in enough detail that somebody who was not there could tell whether it was done. Quantities, materials, locations, finishes, and the standard being met where one applies. This is the clause people write too briefly and then argue about most, because a phrase like repair the bathroom floor covers a range of work an order of magnitude wide and both parties will remember the conversation that narrowed it differently.

Immediately after that, and just as important, say what is not included. Exclusions are the half of scope that nobody writes down and the half that generates the arguments. Site preparation, disposal, permits, painting after a repair, moving furniture, restoring landscaping, or the cost of anything discovered behind a wall all belong here. A short exclusions list is not defensive. It is the fastest way to establish what a price actually bought.

Price, and What Is Allowed to Change It

State the price and state its basis. A fixed price for a defined scope is the cleanest arrangement for both parties. A time-and-materials arrangement needs the hourly rate, the material markup and a not-to-exceed figure, because an open-ended rate with no ceiling is the arrangement customers most often feel ambushed by. Whichever applies, say plainly whether sales tax is included and who pays for permits.

Then name the triggers that change the price, which is the clause that prevents the most common dispute in the trades. Concealed conditions discovered when something is opened up. Changes requested by the customer. Material price movement beyond a stated period, which matters on a job quoted in February and built in June. Delays caused by the customer, such as access not being available on a scheduled day. Each of these should say what happens: work stops, a written change order is issued, and only then does the work resume.

When Money Moves, and Against What

Payment terms need three things: how much, when, and against what event. A deposit that covers materials being ordered rather than an arbitrary percentage. Progress payments tied to defined milestones, meaning something observable like rough-in complete or materials delivered to site, rather than to calendar dates that can slip for reasons nobody controls. And a final payment tied to substantial completion, with any punch list handled through a small retained amount rather than by withholding everything.

State the payment window in days, name the accepted methods, and state the consequence of late payment as a specific rate or fee that appears on every invoice thereafter. A late charge nobody wrote down is unenforceable and a little embarrassing to raise. One that is stated in the agreement and printed on the invoice is simply a term of the deal, and its main function is not to earn interest but to give a customer a reason to pay this invoice before somebody else's.

Schedule Stated as Dependencies Rather Than Dates

A start date and a substantial completion date belong in the agreement, and both should be expressed as a number of working days from a trigger rather than as a calendar date. Work begins within five working days of the deposit clearing and permits being issued is a commitment that can actually be kept. Work begins on the fourteenth is a commitment hostage to a permit office, a supplier and the weather, and the party who wrote it will be the one apologizing.

Alongside that, name the excusable delays: weather, permit and inspection timing, supplier lead times, and anything the customer has to do first, such as emptying a room or selecting a finish. A selection deadline is worth stating explicitly, because a customer who has not chosen tile is the single most common cause of a stalled job and the one contractors are most reluctant to raise in the moment.

What Happens When Something Goes Wrong, and How It Ends Early

A warranty clause states what is covered, for how long, and what voids it. One year on workmanship with manufacturer terms passing through on materials is a common and honest position, and stating it prevents both an unlimited implied expectation and an argument about whether anything was promised at all. Say how a warranty claim is made and how quickly it will be responded to, since the response time is what customers actually remember.

Then say how disputes are handled before they become disputes: a written notice, a stated period to cure, and a step such as mediation before anything formal. Name the state whose law applies and the county where any action is brought, which sounds like boilerplate and matters enormously if the two parties are in different places. Keep arbitration clauses out of a small agreement unless there is a specific reason for one, because consumer arbitration provisions attract scrutiny and several states impose disclosure requirements on them.

Termination is the clause nobody wants to write and everybody eventually needs. Either party may end the agreement on written notice; the customer pays for work performed and materials ordered up to that point; the contractor leaves the site safe and hands over anything already paid for. That short paragraph converts a relationship breakdown from a standoff into a settlement, and its existence makes the breakdown less likely, because both sides know what the exit looks like.

Getting It Signed, and What a Short Agreement Cannot Do

The mechanics matter more than the drafting. Present it as the ordinary way this business works rather than as a precaution, send it before the work is scheduled rather than on the morning of the first day, and accept an emailed signature or a photograph of a signed page, both of which are generally binding. Give the customer a copy at the moment of signing. A contract that exists only in the contractor's truck is a document that will be produced late and read suspiciously.

What a short agreement cannot do is override consumer protection law, and several rules apply regardless of what any document says. Home improvement contracts are separately regulated in many states, with required disclosures and mandatory written change orders. Sales agreed at a customer's home carry a federally mandated cancellation right, the rule the Federal Trade Commission administers for door-to-door and off-premises selling, and a contract that omits the required notice does not remove the right. Licensing and bonding requirements sit outside the agreement entirely.

None of that argues against the one-page version. It argues for knowing which parts of the deal you are writing and which parts were written for you. Everything above fits on a single side of paper in ordinary sentences, takes an evening to draft once and about four minutes to fill in per job, and it does its most valuable work on the jobs where nothing goes wrong at all, by ensuring that both parties spent ten minutes agreeing what they were agreeing to before anybody picked up a tool.
