I am specifically looking for someone with real-world, hands-on experience working on collision repair supplements and negotiating disputed items with insurance carriers.

I am new to the collision repair estimating industry, so the goal is for you to walk me through the process from the beginning using real-world examples.

For example, I want to learn how to:

Compare a body shop estimate/supplement with the insurance carrier's estimate or response.

Match corresponding line items between the two estimates.

Identify exactly what the carrier approved, reduced, changed, or denied.

Understand why the carrier made those changes.

Determine whether the shop has a valid basis to challenge each disputed line.

Use CCC ONE / Mitchell / Audatex information and estimating-system P-pages.

Use OEM repair procedures, DEG inquiries, photos, invoices, and other supporting documentation.

Determine when additional labor or a separate operation is justified.

Write a professional line-by-line rebuttal or supplement response to the carrier.

Understand what happens after the rebuttal is submitted and how subsequent negotiations/supplements are handled.

Real-world examples are required

I do not currently have enough claim examples to provide for the training.

You must therefore have access to real collision repair examples that you are legally permitted to share for training purposes, such as:

a shop estimate or supplement;

the corresponding insurance carrier estimate/revised estimate;

examples showing items the carrier reduced or denied;

preferably the shop's subsequent response/rebuttal;

and, ideally, the carrier's response or final outcome.

All customer, vehicle owner, claim, policy, VIN, contact, or other sensitive information can and should be redacted/anonymized.

I am not looking for confidential documents that you do not have permission to share.

Ideal background

You are a strong fit if you have several years of experience as a:

Collision repair estimator

Body shop estimator

Supplement writer

Collision damage appraiser

Auto damage adjuster/appraiser with strong shop-side experience

Collision claims/supplement specialist

Experience with CCC ONE is highly preferred. Experience with Mitchell and/or Audatex is also valuable.

I especially value candidates who have experience on both the repair-shop side and insurance-carrier side, because I want to understand how both parties evaluate disputed operations.

Format

I would like to work through real examples together over screen-sharing/video calls.

For each example, I want you to explain your reasoning as if you were training a new collision estimator:

“Here is what the shop requested → here is what the carrier changed → here is why → here is what I would challenge → here is the evidence I would use → here is what I would send back.”

This is primarily an educational/consulting engagement, not a request to simply prepare estimates for me. The initial scope is several paid training sessions. If it is a good fit, there may be ongoing work reviewing and validating supplement analyses and draft rebuttals.

When applying, please briefly describe:

Your collision estimating experience.

Whether you have worked shop-side, carrier-side, or both.

Which estimating systems you use (CCC ONE, Mitchell, Audatex, etc.).

Your experience preparing and negotiating supplements.

Whether you have anonymized/redacted real-world examples that we can use during training
