What is a repair order?

A repair order (RO) is the document a repair shop or dealership creates for a service visit. It records the vehicle and its mileage, the customer, the work requested and performed, the parts and labor, and the total charged. Once you pay, it doubles as your service invoice and becomes part of your car's maintenance history.

Do you need to keep old car service records?

Yes. Keep them for as long as you own the car. They prove maintenance was performed if a warranty claim is questioned, document the car's condition for a lemon-law or repair dispute, and — when you sell — show a buyer the vehicle was cared for. A documented car commands a higher resale price than the same car with no records.

How long should I keep car service records?

Keep routine service records for the life of the vehicle and pass them to the next owner at sale. Records for major repairs, recalls, and any work covered by a warranty are worth keeping indefinitely. Because their value is about warranty proof and resale rather than taxes, there's no short retention window — hold them as long as you own the car.

Can a dealer void my warranty if an independent shop services my car?

No. The federal Magnuson-Moss Warranty Act makes it illegal for a manufacturer to void your warranty simply because an independent shop did the maintenance or non-OEM parts were used. If a covered part fails, the manufacturer — not you — has to prove the outside service caused it. Keeping dated receipts that describe the parts and work is how you hold up your side.

Do service records increase a car's resale value?

Yes. A complete service history reassures a buyer that the car was maintained on schedule, which reduces their perceived risk and supports a higher asking price. Two otherwise identical cars can sell for noticeably different amounts when one has documented records and the other doesn't — the paper trail is part of what you're selling.

What's the difference between a repair order and an invoice?

They're usually the same document at different stages. A repair order opens the job and authorizes the work; once the work is finished and priced, it becomes the invoice you pay. Some shops label the final document a 'service invoice' or 'service record,' but all three describe the record of work performed on your vehicle.

Car Service Record (Repair Order)

A car service record — also called a repair order or service invoice — is the document a repair shop or dealership gives you after working on your vehicle. It lists the shop, the service date, the vehicle and its mileage, the parts and labor performed, and the total charged. Together, these records are your car's documented maintenance history.

Overview

Every time a shop changes your oil, replaces brakes, or diagnoses a problem, it produces a repair order or service invoice. Individually each one is just a receipt; collected over a car's life they become its service history — proof of how the vehicle was cared for, what was fixed and when, and at what mileage.

That history does real work. It protects your warranty rights, supports a lemon-law or repair-dispute claim, and raises resale value because a documented car is worth more than an identical one with no paper trail. The catch is that these records arrive a few sheets at a time, years apart, from different shops — which is exactly why they end up lost in a glovebox or a junk drawer.

When you’ll get your Car Service Record (Repair Order)

You had an oil change, tire rotation, or routine maintenance done
A shop diagnosed or repaired a problem with your vehicle
You're keeping proof of service to protect a manufacturer warranty
You're documenting maintenance to maximize resale or trade-in value
You need a repair history for a lemon-law claim or warranty dispute

What’s on your Car Service Record (Repair Order)

These are the fields Granite reads and extracts automatically the moment you upload one.

Repair Shop / Service Provider: The shop, dealership service department, or quick-lube that performed the work.
Service Date: When the work was performed — the anchor for your vehicle's maintenance timeline.
Vehicle (Make, Model, Year & VIN): The vehicle the work was done on. The VIN is highly sensitive — it identifies your specific car.
Odometer Reading: The mileage at the time of service, which ties each record to a point in the car's life and proves service intervals were met.
Repair Order / Invoice Number: The shop's reference number for this visit, used to look the job back up.
Work Performed: A description of the services rendered and any parts replaced.
Parts, Labor & Total: The itemized charges for parts and labor and the total amount paid.

How long to keep it

Keep service records for as long as you own the vehicle, and hand them to the buyer when you sell. Keep records for major repairs and anything done under warranty indefinitely through at least the warranty or lemon-law period.

Unlike a receipt you can toss after the return window, a service record gains value with age. Under the federal Magnuson-Moss Warranty Act, a manufacturer can't void your warranty just because an independent shop did the work — but if a dispute arises, dated receipts showing the parts and service are your proof the maintenance was done. The same documented history is what raises resale value and supports a lemon-law claim, so the full ownership period is the right horizon — not a 3-year audit window.

How Granite handles your Car Service Record (Repair Order)

Granite reads each repair order — shop, date, mileage, work performed, and the vehicle's VIN — and files it automatically into that car's collection alongside its registration, title, and insurance. Instead of a glovebox of fading thermal receipts, you get a complete, searchable service history per vehicle: every oil change and repair in one place, ready to hand a buyer or pull up for a warranty claim in seconds.
