INDEPENDENT REALITY ASSURANCE — AUTOMOTIVE AFTERMARKET

Upload part numbers.
Get back what the
evidence actually supports.

OE numbers, fitment, interchange, competitors, channel pricing, and where selected accounts do or do not show a matching listing. Every answer names the source it came from and the day we captured it. Where sources disagree, you get both.

SHEET 03 / 05  ·  THE PRICE LADDER
METHOD ladder-v2.1  ·  EFFECTIVE 2026-07-01

A retail price tells you one thing. The steps above it tell you the business.

We establish what a part sells for at retail, then what a WD most likely sells it to that retailer for, and what a manufacturer most likely sells it to the WD for.

Retail is observed. The tiers above it are derived, labeled derived, and shown with the schedules behind them.

RETAIL
OBSERVED
12 live listings across two marketplaces and three distributor storefronts. Seller identity and shipping treatment retained per listing.
$54.90–$71.25
WD → RETAILER
DERIVED
Built from three published jobber-net schedules covering this part class, cross-checked against the observed retail spread.
$31.40–$39.90
MFR → WD
DERIVED
Channel margin structure across four comparable programs in the same category and volume band.
$19.80–$25.60
Each tier carries its own source list, capture date and confidence band. Derived tiers state the schedules and comparables behind them under method ladder-v2.1.
PRICE IT BEFORE YOU UPLOAD
How big is your file?

No account, no file, no email. Blanks and duplicates drop out when you upload, so you usually pay less than this.

WHAT COMES BACK, AND WHAT IT COSTS

Priced per part, for the answers you pick. Every tier is a shortcut for a set of services — choose them individually in the run if none of the three fits.

What each tier returns, per part. Rows are services; columns are tiers.

A row that does not resolve is never billed, so the tier price is a ceiling and rarely the figure. Blanks and duplicate part numbers are returned in your file and never charged for.
RUN IT YOURSELF
SHEET 04 / 05 · NOTHING CHARGED BEFORE STEP 04 · REV 2026-08-27

Start with the file you already have.

A column of part numbers is enough. Brand and description help on the hard ones. Your columns come back exactly as you sent them.

Nothing to hand?
Processed for your run only. Never resold, never published, never used as training data.
OR TRY ONE PART

Run a single part number free and see the whole six-stage chain for it. The field is at the top of the page, where the chain is — one place to do this, not two.

It runs in place up there, and the full record lands back here.
Running totals on steps 02–03 are indicative. The price you agree at step 04 is returned by the server against the scope you set — $0.00 on the scope as it stands.
SHEET 05 / 05 · WHY YOU CAN TRUST THE RESULT
OPEN TO ANYONE · NO ACCOUNT · REV 2026-08-27

A finding you cannot check is just an opinion with a price on it.

SOURCE LEDGER
Every cell, every source, one file.

One line per answer: the stage, the source, the date, observed or derived, and the band.

CORRECTIONS
Published against ourselves.

When we get it wrong we publish the original reading, the corrected one, and the cause. Nothing is quietly overwritten.

EVERY ENTRY CARRIES

DETERMINISTIC
No language model writes a value.

No language model writes, infers, guesses or fills any field in your record. Every value is read from a named source by a numbered rule with an effective date, which is why an old run reproduces exactly.

Where a model assists, it only narrows which documents a rule reads. Its output is never a value and never reaches your record.
