Warranty Retail-Rate & Chargeback-Defence AI Agent

Assemble the qualifying repair orders your state's retail-rate submission rests on, run the manufacturer's response clock to the deemed-approval date, and hold the package for the director who certifies it.

What this agent does

Assembles the run, not the certification on it

In

  1. 01

    A repair order closes, and its labour hours, parts cost and pay type are carried onto the qualifying run.

  2. 02

    A repair order carries an oil change beside a real repair, and it is tested on what was done, not on op code.

Reason

  1. 03

    A run is assembled, and the starting repair order, the sequence and each statutory exclusion sit against it.

  2. 04

    A Florida run opens under Fla. Stat. §320.696, where the manufacturer, not the dealer, picks the starting order.

  3. 05

    A submission is transmitted, and the receipt date is captured, because the deemed-approval date runs from it.

Decide

  1. 06

    A response window closes, and the filing is marked approved by operation of law where the statute says so.

  2. 07

    An audit opens, and each line in the auditor's sample is read against that state's audit window first.

Out

  1. 08

    A chargeback lands, and the repair order, the statute it was selected under and the certification stay on file.

  2. 09

    Execute write actions only inside the approval boundaries agreed during implementation.

Product statement

This is not per-claim triage: the agent assembles the rate submission and the post-audit defence, and the fixed-operations director certifies both.

Example workflow

One submission, run to certification

  1. 1Repair orders receivedDMS repair-order export, parts invoice or accounting extract
  2. 2Sample assembledLabour hours, parts cost, pay type and close date, each with its named source
  3. 3Rate proposedEffective labour rate, parts markup, clock dates and confidence
  4. 4Controls appliedQualifying tests, sequence integrity, lookback and audit windows, and confidence threshold

No human action required

Stages 1 to 4 run unaided, and nothing is submitted at any of them — the agent is assembling, and the director's lane opens at the confidence gate.

5DecisionBranches at the confidence threshold
High confidence

Goes to the fixed-operations director.

Low confidence

Adds a franchise-counsel read first.

Director approval

The submission is held with its repair orders, its exclusions and the confidence.

Approve · Amend · Send to counsel review

Approved — released to certify

  1. 6Warranty systems updatedOnly where write access and approval policy allow it
  2. 7Outcome evaluatedAmendment rate, exclusion disputes, deemed-approval dates and chargeback outcomes

Amendments

Every director amendment is counted in the evaluation.

What should not run autonomously

Human approval stays in control

Outside the boundary — human approval required

8 items

  • Certifying the retail-rate submission to the manufacturer.
    • Deciding that a contested repair order stays in the run.
    • Conceding a chargeback or agreeing an extrapolation.
    • Choosing when, and in which state, to re-declare a rate.

  • Automation boundary

    Agent acts unaided

    • ✓Assemble the qualifying run from closed repair orders.
    • ✓Carry each inclusion or exclusion with the rule behind it for the named owner.
    • ✓Compute the rate and markup, and run the response clock.
    • ✓Flag the orders the director should weigh, and hold the run for them.

    Any write happens inside the boundaries agreed at implementation, never ahead of certification.

    • Signing the dealer's response to an audit finding.
    • Settling a chargeback inside the manufacturer's portal.
    • Waiving a statutory meeting or response window.
  • Changes to qualifying, clock or certification rules.

Example output

One repair order, annotated

Everything the agent assembles is attached to the repair order it was drawn from.

As received

Taken from the DMS repair order and the parts invoice — nothing on this side is inferred.

Evidence used

  • Closed repair order
  • Parts invoice line
  • Labour-op record

Why this status

A customer-paid nonwarranty repair, so the maintenance exclusion does not reach it.

What the score decides

Below the configured threshold the run picks up a counsel read before the director.

Value

Where AI adds value

The same four claims, placed at the point in the workflow where each one applies.

Where the value lands

Value 01 – 04

Every repair order

From the DMS

03Qualifying

Assemble against your state

Draw on the closed repair orders on file and the statute in force in that state on the submission date.

01Approved path

Silence can mean approved

Routine orders arrive already tested, with the rate and the markup computed.

02Human review

Send review to the contested lines

Excluded orders and low-confidence tests are marked first, because manufacturers carrying record warranty cost audit harder.

04

Build an evidence trail

The repair order, the statute it was selected under and the manager who certified stay on the submission.

Agent controls

Six layers between the model and the submission

The controls narrow inward through six stages. What emerges uncaught is set out in the map below.

How Nestack evaluates it

Evaluate the submission workflow — not only the rate at the end.

Coverage runs the whole depth of the workflow, and every layer is cut by slice.

Surface — the rate the manufacturer sees

  1. E1Final-output evaluationDid each repair order in the run pass that state's qualifying test?
  2. E2Step-level evaluationDid the agent use the right orders, statute version and lookback window?
  3. E3Tool evaluationDid it read and write the correct repair order and the correct field?
  4. E4Confidence calibrationDo low-confidence runs actually attract more director amendments?
  5. E5Slice evaluationHow does performance change across specific franchise groups?
  6. E6Business outcomeHow many submissions needed an amendment, or a defence after audit?

Affected slices

One franchise can carry the exposure

A blended approved rate across the group hides the franchises that absorb the amendments and the chargebacks — and no public dealer-side chargeback rate exists to benchmark against. Nestack reports by slice, not in total.

Evidence-linked improvement

Every cycle ends by adding a case

A cycle ends when the abandoned submission is a case the next release has to catch. That suite is what the next rate filed is measured against.

Improvement cycle · five stages

Switchback — the path turns at Improve and returns at Learn

  1. 01

    Detect

    Amendment rate rises in a franchise slice.

  2. 02

    Diagnose

    The rate filing that was abandoned on day thirty-one is read back to a single cause.

  3. 03

    Improve

    Number the correction, and keep the submissions that surfaced it fastened to it.

  4. 04

    Verify

    The touched cases go round once more, and one failure keeps the release where it is.

  5. 05

    Learn

    It becomes a fixture of the suite, and the state rules follow it.

  6. Learn → Detect

    The return edge. The next rate is filed against a suite one case longer.
