Auto Repair Authorization Checklist: What to Record When a Shop Proposes Additional Work

The short answer

An auto repair authorization checklist is a record of what you agreed to let a shop do to your vehicle and how much you agreed to pay. The most important part is the additional authorization record. This is a separate log you fill in each time the shop asks to go beyond the original estimate. For each request, it should capture the proposed extra work, the reason given, the revised total, any spending limit you set, how and when the shop contacted you, who approved the work, and which supporting documents back it up. Below is a checklist and a plain-text template you can copy into a document and save or print as a PDF.

One condition matters more than any other. Whether a particular approval is legally valid depends on your state, and sometimes your county or city. A checklist helps you keep consistent evidence of what was agreed. It does not make an authorization legally sufficient. Check the rules where the repair is done, such as Florida's motor vehicle repair requirements for a Florida shop.

Terms you will see on repair paperwork

• Estimate: the shop's projected cost for a defined scope of work, usually split into parts and labor.
• Work order or repair order: the document that describes the job and, once signed, typically records your approval to proceed.
• Authorization: your consent for the shop to perform specific work, up to a specific amount.
• Additional or supplemental authorization: a new consent for work or costs beyond what the original authorization covered, often requested after the shop finds something during diagnosis or disassembly.
• Approval limit: a dollar ceiling you set, above which the shop must contact you again before continuing.
• Teardown or diagnostic charge: a fee for the inspection or disassembly needed to produce an estimate. It may be owed even if you decline the repair, depending on what you signed.

The word 'authorization' can also carry a narrower, contract-specific meaning. Some insurance policy language defines authorization to repair as the moment you sign the work order at the repair facility, or the moment repairs on the covered vehicle begin. If an insurer is paying for the repair, read how your own policy defines the term. That definition can affect timing and coverage separately from your agreement with the shop.

Drop-off authorization versus the additional work record

Many people search for a single repair authorization form, but these are two different records. Keeping them apart makes disputes easier to resolve.

Aspect | Initial drop-off authorization | Additional repair authorization record

When it is created | Before work begins, usually at the counter | Each time the shop proposes work or cost beyond the original approval

What it covers | Vehicle details, your stated concern, the initial estimate or diagnostic scope, your contact preferences | The newly proposed work, reason given, revised amount, your decision, and how consent was communicated

Who usually prepares it | The shop's work order, signed by you | Often the shop's records plus your own log; keep your own copy either way

Common gap | Vague concern descriptions such as 'check noise' with no dollar limit | Phone approvals with no written record of the amount or time

Suppose you bring a car in for one concern, such as a suspected alternator problem. Approving that diagnosis or repair does not by itself show that you approved unrelated work the shop later recommends. Each new item should have its own entry in the additional authorization record.

Checklist: additional repair authorization record

• Original reference: work order or estimate number, date, and the originally approved amount.
• Vehicle identification: year, make, model, VIN, and odometer reading at drop-off.
• Request number: a sequence number for each additional request (1, 2, 3…) so revisions are not confused.
• Proposed additional work: a specific description of the parts and labor, not a general phrase.
• Reason given: what the shop says it found and how it found it, such as a measurement, inspection result, or teardown finding.
• Revised amounts: the cost of the additional item, the new running total, and whether taxes, fees, and shop supplies are included.
• Approval limit: any ceiling you set, stated as a dollar figure, and whether it applies to this item or to the whole job.
• Your decision: approved, declined, or approved in part, with exactly what was included.
• Communication method: in person, phone, text, email, or app message.
• Communication date and time: when the shop contacted you and when you gave your answer, if those were different times.
• Names: the shop employee who contacted you and the person who gave approval.
• Supporting documents: revised written estimate, photos of the failed part, inspection or test printouts, text or email screenshots.
• Returned parts: whether you asked to see or keep the replaced parts.
• Confirmation: whether the shop sent a written or electronic confirmation of the revised authorization, and where you saved it.

Recording phone and text approvals

Phone approvals are where disagreements most often start, because the only record may be a note in the shop's system. Right after the call, send a short text or email back to the shop. Restate what you approved, the amount, and any limit. For example: approved replacement of the item described, total not to exceed the stated figure, call before anything else. Then log the call time, the message time, and the shop's reply in your record. If you decline an item, state that in writing too.

If the shop did work you did not approve

Start by asking for a detailed, itemized invoice and the shop's repair documentation, including any record of when and how it says it obtained your approval. Compare that against your own authorization record and the original work order. Your checklist entries show what you agreed to, but they cannot settle whether you owe for the disputed work. That depends on the governing rules and on what you signed. If the shop will not resolve the difference, your state or local consumer protection agency can explain the process for repair complaints where you live.

Florida and other jurisdictions: what to verify

Several states, and some counties, regulate how repair shops must estimate and get approval for work. Some local agencies publish sample repair authorization forms for shops in their area. A sample from one jurisdiction is not a template for another, and the requirements were not reviewed for this guide. If the repair is in Florida, check the current state motor vehicle repair requirements with the state consumer services authority before relying on any form. In particular, confirm:

• Whether a written estimate is required, and above what amount.
• Whether, and how, a customer can waive a written estimate.
• How far a final bill may exceed the estimate without further consent.
• What form additional consent must take, such as written, oral, or electronic, and what the shop must record when consent is oral.
• Whether shops must offer to return replaced parts.
• Whether the shop must be registered and how to check its status.
• Where and how to file a complaint.

Limits of this checklist

This guide does not provide specific dollar thresholds, tolerance percentages, or required form wording for any state. That information was not part of the material it was built from, and it varies by location. The template is a record-keeping aid, not a legal form, and using it does not guarantee that an approval meets local requirements. For warranty or insurance-funded repairs, the warranty provider or insurer may have its own approval steps that apply alongside the shop's process.
