Paperwork guideAppliance Repair Service Agreement: What Every Contract Needs
The service agreement is the most underrated profit-protection tool in the appliance repair business. Every dispute you've ever heard about — the "you never told me," the refused payment, the warranty argument — traces back to something that wasn't in writing. Here's what belongs in yours, clause by clause.
Note: this is business guidance, not legal advice. Have a local attorney review your final agreement — a one-hour review is cheap insurance.
Why a written agreement on every job
Three reasons, in order of how often they save you: (1) It prevents disputes — most customer conflicts are memory conflicts, and paper wins memory contests. (2) It speeds payment — a signed agreement with payment terms turns "I'll pay you next week" into an obligation. (3) It looks professional — handing a customer a clean, printed agreement signals "established business" and justifies professional pricing. Verbal quotes are for handymen; written agreements are for companies.
The 9 clauses every agreement needs
1. Parties and scope of work
Your business name, the customer's name and service address, the appliance (make, model, serial number), and a plain-English description of the work authorized. Specificity matters: "Replace refrigerator ice maker assembly" beats "fix fridge." If the customer later claims you were supposed to do more, the scope line settles it.
2. Diagnostic fee and estimate structure
State the diagnostic fee ($89–$129), that it's due regardless of whether the repair is approved, and that it's credited toward the repair when approved. Then state whether the repair quote is a firm fixed price or an estimate with a not-to-exceed cap (e.g., "estimate $289, not to exceed $349 without written authorization"). The cap protects you from open-ended liability on jobs with hidden complications. See our pricing guide for how to set these numbers.
3. Parts: new vs. refurbished, markup disclosure
Specify whether parts are new OEM, aftermarket, or refurbished — and get the customer's initials if anything isn't new OEM. This single line prevents the most common parts dispute in the business. You don't need to disclose your wholesale cost, but you do need to disclose the part's nature.
4. Labor warranty terms
State your labor warranty plainly: "90-day warranty on labor; manufacturer warranty applies to parts." Define what triggers it (same failure, same appliance) and what voids it (customer tampering, power surges, unrelated failures). Shorter than you think is fine — 30 days is the industry floor, 90 days is the professional standard. Longer warranties sound generous but multiply your free-callback exposure.
5. Payment terms
When and how you get paid: "Payment due upon completion" for residential; "Net 15" for property managers. List accepted methods. State your late-payment policy (e.g., 1.5% monthly service charge) — you'll rarely enforce it, but its presence accelerates payment. For large jobs, a 50% deposit before ordering expensive parts is standard and should be in writing.
6. Cancellation and rescheduling
Your policy when the customer cancels: same-day cancellations forfeit the diagnostic fee; rescheduling with 24 hours' notice is free. Without this clause, you'll drive across town to empty houses. With it, most customers either keep the appointment or pay for your wasted trip.
7. Limitation of liability
Cap your liability at the amount paid for the service — standard and enforceable in most jurisdictions. Include a line excluding liability for pre-existing conditions ("not responsible for pre-existing damage discovered during service") and for food spoilage beyond a stated limit. You're repairing the appliance, not insuring the customer's groceries.
8. Authorization to perform work
The customer's signature authorizing the specific work at the specific price. This is the clause that turns your agreement from a quote into a contract. No signature, no work — make it a non-negotiable step in your job process, even for "quick" jobs. Quick jobs generate disputes at the same rate as big ones.
9. Dispute resolution
A simple line: "Disputes will be resolved through binding arbitration in [your county] / small claims court." This discourages frivolous disputes and keeps any real ones in the cheapest possible forum. The FTC's consumer guidance (ftc.gov) is a useful reference for what's considered fair in consumer service contracts.
Estimates vs. firm quotes: choose deliberately
| Firm fixed price | Estimate with cap | |
|---|---|---|
| Best for | Standard, predictable jobs (80%+ of residential work) | Jobs with unknowns (water damage, sealed-system-adjacent, elderly appliances) |
| Customer appeal | Highest — no-surprise pricing | Good, with the cap as the safety net |
| Your risk | You eat overruns | Shared, bounded risk |
| When to use | Default for everything routine | When you genuinely can't see the full problem yet |
Default to firm fixed pricing — it's what customers prefer and it pairs with flat-rate pricing. The Small Business Administration's contract basics (sba.gov) are a solid cross-check for the commercial terms in your agreement. Reserve estimates-with-caps for genuinely uncertain work, and always explain why this job gets an estimate instead of a fixed price. Transparency about uncertainty builds more trust than false precision.
Handling the disputes anyway
Even perfect paperwork won't prevent every dispute. When one arrives: (1) stay calm and reference the signed agreement — "Let's look at what we agreed to" defuses most situations; (2) distinguish warranty issues (fix promptly, cheerfully — it's your reputation) from scope disputes (point to the scope line); (3) for payment refusals, a formal demand letter referencing the signed agreement resolves the vast majority without further action; (4) small claims court is the backstop — with a signed agreement, these cases are usually straightforward.
The golden rule: the agreement isn't there for the 95% of customers who are lovely — it's there for the 5% who aren't, and for the misunderstandings that happen with lovely people too. Ten minutes of paperwork per job prevents the disputes that cost you days.
Frequently asked questions
Do I really need a written agreement for small jobs?
Yes — especially small jobs. A $189 dryer repair generates disputes at the same rate as a $600 refrigerator job, and small-job customers are the most likely to balk at paying. One page, one signature, every time.
Can I use a generic contract template from the internet?
As a starting point, yes — but have a local attorney review it before use. Consumer protection rules vary by state (some states have specific home-service contract requirements), and a one-hour attorney review costs far less than one lost dispute.
What warranty should I offer on labor?
90 days is the professional standard; 30 days is the floor. Match your warranty to your callback confidence — if your callback rate is under 3%, a 90-day warranty costs you almost nothing and sells jobs.
How do I handle a customer who won't sign?
Don't do the work. "I need your signature before I can start — it's what guarantees your warranty and your fixed price." Customers who refuse to sign are telling you exactly what kind of transaction this will be. Believe them.
Should the diagnostic fee be separate from the repair quote?
Yes — list it as its own line, state it's credited toward the repair when approved, and collect it upfront. Separating it makes the credit feel like a discount when they approve, which lifts close rates.
