Auto Repair Invoice Template
This free auto repair invoice template is built for independent shops, mobile mechanics, and one-bay operations that have to hand a customer a bill they can actually read. A repair invoice does a job most invoices do not: it has to show what was wrong, what you replaced, and what the labor took, so the number makes sense to someone who never saw under the hood. Parts on their own lines, labor in hours at your posted rate, the diagnostic fee and shop supplies stated plainly — that is what turns a big total into an explained total, and it is what stops the argument at the counter.
The generator below is pre-filled with a realistic brake job — a diagnostic line, labor hours, two parts lines, and a shop supplies charge — so you can edit it into your own repair order in a couple of minutes. Change the vehicle, the parts, and your labor rate, then download the finished PDF and hand it over at pickup or email it before the customer arrives. Everything a customer asks at the counter is already on the page: what it was, what it cost, what is covered, and how to pay you.

How to fill out an auto repair invoice
Put your shop details at the top
Lead with the shop name exactly as it appears on your bank account, then the street address, phone, and email — customers call the number on the invoice first when something comes back. Some states require a repair-shop registration or license number on every invoice, so if yours does, give it a line of its own here.
Add the customer and the vehicle
Name, phone, and billing address for whoever pays — the owner, a fleet manager, or an insurer. Then identify the vehicle: year, make, model, mileage in, and the VIN or plate. The vehicle line is what turns a bill into a repair record, and it settles which car you worked on when a household brings in three.
Number and date it like a repair order
Use one running sequence and never reuse a number. If your shop writes repair orders, keep the RO number and the invoice number tied together so the ticket, the parts receipts, and the bill all match. Date it the day the vehicle is ready, and set the due date to pickup unless the customer has an account with terms.
Name the complaint, then the repair
Write the concern in the customer's own words — "grinding noise when braking," "check engine light, rough idle" — and then the work you actually performed. A line that says only "brake job" invites questions; a line that says what came off, what went on, and why is what a customer forwards to a spouse or a fleet manager without calling you.
Split parts and labor onto separate lines
Parts get a quantity and a unit price, so two rotors read as two rotors. Labor goes on its own line in hours at your posted rate — 2.5 hours at $125, not a lump sum. Sublet work like machine shop, alignment, or glass gets a line too. This split is the first thing customers, fleets, and warranty administrators look for.
Add diagnostic time, supplies, and fees
Put the diagnostic charge on its own line. If you credit it toward the repair once the customer approves the work, show that credit as a negative line so they can see you kept your word. Add shop supplies for the rags, cleaners, and fasteners nobody itemizes, plus any disposal fee for oil, coolant, or old tires.
Set the tax line for your state
Many states tax parts as tangible goods but leave repair labor untaxed, and others tax both. The tax box here applies one rate to the whole subtotal, so if only parts are taxable, work out that tax and enter it as its own line instead. The sample uses zero — check your state's rules and set what you actually remit.
Close with warranty, terms, and payment
State your warranty on parts and labor in plain terms — a period, a mileage, and what it excludes, such as customer-supplied parts. Then say when payment is due, which is at pickup for most shops, and list every method you take. If you hold the vehicle until the bill is settled, put that on the invoice too.
Billing tips for auto repair invoices
Estimate first, authorize before you turn a wrench
Many states have auto repair rules that require a written estimate and the customer's approval before work begins, plus fresh approval when the final bill will run meaningfully past that estimate. The thresholds and the wording differ by state, so check yours. Keep the approval — signed, emailed, or texted — with the repair order. The invoice should never be the first time a customer sees a number, and a shop that gets authorization in writing almost never argues about one.
Parts and labor are often taxed differently
Sales tax on parts is common because parts are tangible goods; repair labor is untaxed in a lot of states but taxable in others, and some states change the answer for warranty or fleet work. This template's tax box applies a single rate to the whole subtotal, so if your state taxes only parts, calculate that amount and add it as its own line rather than taxing labor by accident. The sample sits at zero on purpose.
Shop supplies and diagnostics, charged fairly
A shop supplies line covers the cleaners, rags, fasteners, and lube that are real costs but not worth itemizing. Show it as its own line rather than burying it in the labor rate, and keep it proportionate to the job. Do the same with diagnostic time: charge for it, because finding the fault is the skilled part, then credit it toward the repair when the customer goes ahead and let the invoice show the credit.
Put your warranty on every invoice
Write the parts and labor warranty on the bill — how long, how many miles, and what it does not cover, such as customer-supplied parts or wear items. It takes one line and it settles most comeback conversations before they turn into arguments, because both of you are reading the same terms. Fleet customers and extended-warranty administrators also look for that language before they approve payment.
Getting paid at pickup, and billing accounts
Most repair work is paid when the customer collects the keys, so have the invoice printed or emailed before they arrive and list card, cash, and transfer options on it. Fleet, dealer, and body-shop accounts are different: they usually want a purchase order number on the invoice and pay on terms, so add the PO to the header and set a real due date instead of leaving it open.
Frequently asked questions
What should an auto repair invoice include?
Your shop name, address, and phone, the customer's details, and the vehicle — year, make, model, mileage, and VIN or plate. Then the complaint, the repair performed, parts listed with quantities and unit prices, labor shown in hours at your rate, and any diagnostic, shop supplies, or disposal charges. Finish with the subtotal, tax, total, your warranty terms, and how payment is due.
How do I bill parts and labor separately?
Give each its own line. Parts take a quantity and a unit price so the customer can see two rotors at one price each, and labor takes the hours you actually billed at your posted hourly rate. Keeping them apart makes the invoice easy to check, matches how most states apply sales tax, and is what fleet managers and warranty payers expect to see before they release payment.
Should the diagnostic fee be credited toward the repair?
That is your call, but crediting it is a common and effective policy: you charge for diagnostic time up front so tracing the fault is paid work, then apply it against the repair when the customer approves the job. If you do that, show the fee and the credit as separate lines on the invoice. The customer sees exactly what happened, and you still get paid when they decline.
Do I need the customer's approval before starting work?
In many states, yes — auto repair rules commonly require a written estimate and the customer's authorization before you begin, and a second approval when the final bill will exceed the estimate by more than a set margin. The specifics vary by state, so look up your own. Even where it is not required, getting approval in writing protects you, and a text or email is usually enough.
Do I charge sales tax on auto repair?
It depends on your state. Parts are taxable in most places because they are tangible goods, while repair labor is exempt in many states and taxable in others. Because this template applies one tax rate to the whole subtotal, the cleanest approach when only parts are taxable is to calculate that tax yourself and enter it as a line item. Check your state's rules before you bill.
What is a shop supplies fee?
It is a small charge covering the consumables a job uses but nobody lists separately — cleaners, rags, fasteners, lubricants, and shop towels. Charging it is normal practice, but keep it a visible line on the invoice and keep it proportionate to the work rather than a flat surprise on a small job. Some states cap or regulate how it can be presented, so check before you set yours.
How should I invoice a warranty comeback?
Write it up as a full invoice — vehicle, complaint, parts, and labor hours — and then zero out the amount due with a warranty credit line that references the original invoice number. You end up with a complete record of the work at no charge to the customer, which matters if the part fails again or you are claiming against a supplier. The Paid app keeps the original invoice on file so you can pull the number up on the spot.
