A fridge fix invoiced on a text message reads like a hobby. The same fix on a clean, itemized invoice — service call, model and serial, flat-rate repair, parts — reads like the shop the customer meant to hire. Here's exactly what goes on it.
Nine things. Miss one and you either look small-time, lose a warranty dispute, or wait longer to get paid.
Business name, phone, email, and your registration or license number if your state issues one. This is the difference between "some guy" and a business — put it at the top of every invoice.
Brand, model, and serial number. It ties the work to one machine, protects you if a warranty claim comes back, and makes the next parts order a 30-second lookup instead of a second trip.
The diagnostic fee is its own line. If you credit it toward the repair, show the credit too. A customer who can see you honored the fee pays without the phone call.
"Replace control board — $260" beats an hourly breakdown. Flat-rate is how appliance work is quoted, and it's what the customer approved before you ordered the part.
Each part with its price. Keep your cost private — the customer sees the price, your books see the margin. That gap is your real profit, and you should know it per job.
Sales tax if your state taxes repair labor or parts, one clear total, and the ways you take money — card, Venmo, Zelle, Cash App. The fewer steps to pay, the sooner it's paid.
Whatever you stand behind — commonly 90 days on labor and the part's own manufacturer warranty — in one line. It heads off the callback argument before it starts.
Sequential number, date of service. Your tax preparer needs it, a small-claims judge respects it, and a numbered invoice is harder to "forget" than a text.
Refrigerator not cooling. Diagnosed as a failed control board, fee credited into the flat-rate repair.
| Item | Amount |
|---|---|
| Service call & diagnosis | $95.00 |
| Replace main control board (flat rate) | $260.00 |
| Service call credited to repair | −$95.00 |
| Sales tax (8.25%) | $21.45 |
| Total due | $281.45 |
Quote $95 on the phone, then hide it inside a bigger number, and the customer feels played. Show the fee, show the credit. Trust is the fastest route to "paid."
Six months later the board fails again. Without the serial on paper, you're re-diagnosing for free and arguing about which fridge you fixed. Two lines of text prevent all of it.
"You owe me $281" in a text thread has no number, no terms, no record. It also gets forgotten. A real invoice gets paid faster because it's obviously owed.
One machine, two promises, one clean piece of paper. Here's what has to be agreed to before the invoice exists — and what the app does about it while you're driving to the next call.
A handyman bills hours. A landscaper bills the visit. You bill a diagnosis, then a repair: two separate promises, made at two separate moments. They agreed to the fee on the phone and to the fix after you named the board price, so the invoice has to show both, plus what happened in between. Leave one out and the total feels invented — invented totals get questioned, delayed, and negotiated after the work is already done. A photo of the scorched board next to the new one, saved on the job, defends the number better than any explanation.
Approve stays dead until the customer types their name. After that the job carries who approved it and on what date, sitting right above the line items — so the "I never said yes to that" conversation has an answer on paper. Standing at the machine? Hand them your phone. It opens that same approval page, so an in-person yes leaves a real signature instead of a note you wrote yourself.
You're in for the pump and the belt is shot too. Add the line and the approval page comes back at the new total for a fresh authorization — the old yes doesn't quietly stretch to cover it. An estimate nobody answers expires after 14 days instead of hanging open at a price you set two months ago.
The invoice that arrives while the fridge hum is still fresh gets paid; the one that shows up nine days later waits behind the water bill. When the customer opens an estimate, your phone buzzes — that's the minute to call. If they never answer it, one nudge goes at three days and one more at seven, English or Spanish, then it stops for good.
A real appliance repair is usually two visits: the diagnosis, then the fix once the part lands. Where the review ask lands, and what the invoice looks like, decide who calls next.
Visit one ends with the washer still broken and a pump on order. Ask for the review there and the customer is rating a $95 diagnosis with no outcome yet. Ask at the end of visit two, after they've watched a full cycle finish, and the review lands on the thing they hired you for. The app follows your lead here: the request goes out on the job you mark done or paid, one reminder three days later, and it stops the moment a rating comes in.
Google and most platforms prohibit incentivized reviews. A discount code or a gift card can get your whole history wiped — the ten you earned honestly go with the two you paid for. Hand over a card or a text link, say plainly that reviews are how the next customer finds you, and leave it there. A review with nothing riding on it can't be taken away from you later.
A customer who calls back for the dryer six months after the washer is booking at full rate with zero marketing cost attached. You earned that lead by fixing the first machine right the first time — which also keeps your labor on new problems instead of return trips. When they do call, copy the old job: same customer, same unit, every line at the price you already charged, the old fee credit left off. Edit what's different and send it.
Skip the referral fee; neither side wants to manage it. A property manager wants a tech who answers, shows up in the window promised, and sends an itemized invoice their bookkeeper can file without a question. Break that $220 washer job out the way our own rate data splits it — labor runs about 55%, so call it $121 labor and $99 pump — and there's no mystery line that looks padded. The invoice is what gets forwarded to the next unit. A five-star badge isn't.
Flat-rate, not hourly: a service call to diagnose, then one price per repair, agreed while you are both standing at the machine. These are the flat-rate menu prices SideWRK preloads into a new appliance operator's estimate form — a menu, not a meter, and every number editable to your market.
| Service | Starting price |
|---|---|
| Diagnostic / service call | $95 |
| Washer repair | $220 |
| Dryer repair | $200 |
| Refrigerator repair | $320 |
| Dishwasher repair | $240 |
| Oven / range repair | $260 |
Every price lands on a branded estimate the customer approves from their phone — that's how SideWRK runs appliance repair side work end to end.
The $95 service call is its own line. When the customer takes the repair, the credit comes prefilled at the fee already sitting on the job — one confirm, and it lands as its own negative line, capped so it can never drag the invoice below zero.
An out-of-town call can carry a billable mileage line: miles times your rate, shown to the customer as its own travel charge instead of hiding in the repair price. On or off per job. Your call.
Log the purchase date and the app flags a unit under a year old. Most appliances carry a one-year parts-and-labor warranty, so the brand may fix it free. Telling the customer costs you this job — and earns the next five, because now you're the tech who told them.
The data a job already captured keeps working after you leave: the parts in the truck, the model on the record, the honest verdict that ends the visit.
Name a part once and the app recognizes it from then on, scan or search. Use one on a job and the count drops. Each item carries its own reorder point — "3 of these" or "my last one" — so you find out you're low before the next drive instead of in a customer's kitchen.
The job already knows the unit's brand and model, so the part search starts from the machine's own model number. The right board, pump, or seal, without a catalog dig or a second trip to squint behind the kickplate.
Repair quote over half the price of a new machine, on a unit past half its expected life? Say replace. The repair-or-replace guide walks every appliance, with refrigerators and dishwashers broken out. Calling replace when the numbers say so is what earns the next call.
All three run on a sample business in the live appliance repair demo — open it free, no signup.
Pick the appliance and the failure for a typical national band, put your own rate in, and see the flat price, the real profit, and the repair-or-replace verdict. It runs free, right here.
Six fields at the first visit, and the record works for years: the callback, the reorder, the warranty question, and April.
Every job carries the appliance itself: category, brand, model, serial, the purchase date behind the warranty check, and whether it runs on gas. That's the paper trail that ends the which-fridge-was-it argument and turns the reorder into a lookup instead of a housecall.
Numbered invoices, payments, parts costs, and scanned receipts roll into a year-end wrap-up: rows, category totals, CSVs, and a printable summary your preparer can actually use. The shoebox of receipts, gone.
Most appliance repair needs no special license. Sealed refrigeration is different: opening a refrigerant circuit takes EPA 608 certification, and gas appliances are their own safety category. SideWRK keeps the records — license number on every invoice, part condition, the notes — and meeting the requirement stays yours. The app is the notebook, not the permit.
Your business name and license or registration number, the customer's name and address, the appliance brand, model, and serial number, the service-call fee and whether it was credited, the repair as a flat-rate line, parts with prices, sales tax if your state requires it, the total, how to pay, and your parts-and-labor warranty terms.
Yes — always show it as its own line, then show the credit if you rolled it into the repair. Customers who can see the fee was honored complain less and pay faster.
It ties the work to one specific machine. That protects you on warranty claims, speeds up the next parts order, and looks like the manufacturer-level paperwork customers expect.
Yes — SideWRK's free invoice generator runs in your browser, no signup. Fill in your business, the appliance work, and the amounts, then print or save it as a PDF.
In SideWRK, the estimate the customer approved becomes the numbered invoice — appliance, serial, parts, tax, and your license on it. Then it tracks whether you got paid, and what you actually made. The playbook above is the whole trade on paper, or see it working in the live appliance repair demo.
