Auto Repair Approval: Estimates and Added Work

Imagine a customer says, “Take a look at the brake noise.” The shop diagnoses worn parts, orders replacements, and begins repair. The customer thought the approval covered diagnosis only. Even a reasonable repair price cannot answer the missing question: what work was authorized?

An auto-repair approval needs both a defined job and a price boundary. A spending cap does not authorize unrelated work merely because it fits below the cap.

Get a decision at each change in scope

Start with an automotive estimate and record the decision in the repair authorization.

• Diagnosis: tests, access, charge or maximum amount, reassembly requirements, and stop point.
• Repair: identified parts and labor, price, applicable disclosures, and excluded recommendations.
• Added work: new finding, revised scope and total, schedule effect, and authorization before proceeding.

The FTC's Auto Repair Basics recommends written estimates and a limit beyond which approval is needed. That guidance does not establish a nationwide statutory overrun allowance.

Explain whether the diagnostic fee is separate, included, or credited toward repair. The OBD-II report guide helps distinguish a scan from further diagnosis and a confirmed repair recommendation. An inspection report supplies findings; it is not customer permission to carry them all out.

State examples: do not copy one threshold everywhere

These are examples within their respective rules and exceptions. They do not authorize unrelated repairs, override a lower agreed limit, or replace state-specific forms. A shop policy of obtaining approval before any increase gives staff a clear operating stop point.

Save exactly what the customer accepted

Each approval should identify the vehicle, repair-order number, estimate revision, work, price or limit, approving person, method, date, and time. Preserve required disclosures and a customer-copy record.

An illustrative approval note could read:

Customer approved revised estimate R-208-R1 by text before added work: replace the identified front brake hose; revised total and diagnostic-fee treatment as itemized in that estimate. Rear brake recommendation declined. Accepted estimate and message saved with repair order R-208.

That note indexes the evidence; it does not replace the estimate or legally required content. Follow the written-quote workflow to retain the accepted version. The signed-change guide explains the same timing principle for field work.

Where electronic approval is allowed, save the complete exchange. The ESIGN Act generally protects electronic records from rejection solely because of their format while preserving other requirements. It does not make a vague “OK” a complete authorization.

Keep the technician and invoice inside that approval

Carry approved scope and stop points into the automotive work order. If the customer cannot be reached, document attempts and stay within existing authority. Do not treat silence or a generic additional-repairs checkbox as approval.

Keep insurer, fleet, and warranty-administrator payment decisions distinct from customer authorization. Record who may approve the work and what balance the customer accepted. California BAR, for example, restricts who may be designated for additional authorization, including excluding an insurer involved in the claim.

Before sending the invoice, reconcile completed work to the original estimate and every revision. Include the required parts, fee, tax, warranty, and authorization information on the correct documents. The repair-order workflow connects that file to findings, tests, declined work, and release.
