Gauge interface comparing a supply contract's pricing structure against the Mills formula

Overview

A rack supply contract hides its economics in structure: which index each supply point prices off, what differentials ride on top, whether you're paying the lower of two formulas. That structure is what you negotiated, and it is what you will negotiate again. Gauge reads it the way a market analyst would, straight from the PDF.

Upload a contract, pick the pricing pages, and Gauge transcribes every priced line verbatim: index references, differentials, seasonal windows, and lower-of and higher-of structures. Every adder stays visible as its own line. Every supply point, counterparty, spec, and index series is then linked to its Atlas entity, so a contract line becomes a door into the terminal, company, or benchmark behind it.

Then comes the gauge itself: each line's formula is laid out component by component against the Mills canonical spot-to-rack formula for that terminal city and spec. Negotiable levers (RIN credits, adders, lower-of structures, auto-renewal and take-or-pay clauses) are called out, and a counteroffer column lets you sketch the deal you'd rather have, side by side with the one you signed. Differences in indexes, coefficients, and adders are the negotiable gap.

Key information

Use cases

Negotiate supply contracts with confidence

Wholesalers and jobbers need to know what a supplier's quoted adder actually pays for by decomposing the contract formula into index, tariff, terminaling, blending, RIN, and margin components, in order to negotiate the adder down at renewal. However, suppliers quote one all-in number, the buyer has no independent cost build to argue from, and the only play left is "let the supplier quote first, then haggle."

Mills Gauge arms the wholesaler and jobber by extracting every priced line verbatim and laying it against the Mills canonical spot-to-rack build (including blendstocks, biofuels, RINs, and adder) for a given rack terminal city and product specification, which results in a component level counteroffer: the buyer can show that a quoted 8 cent adder covers roughly 1 cent of modeled cost.

Compare RFP bids apples-to-apples

Retailers and fuel end users need to compare dozens of supply bids across 160 markets by rebuilding every bid on a common cost basis, in order to award a $5B annual RFP to the lowest true delivered cost. However, bids arrive on non-standard terms and three different indexes (Platts, Argus, OPIS), and the team hand-builds price buildups in Excel from public data scattered across pipeline, terminal, and regulatory websites.

Mills Gauge normalizes the retail end user's bid stack by extracting each supplier's structure and pricing it against one canonical formula per city and spec, which results in an apples-to-apples comparison of the whole bid stack in hours.

Benefits

Verbatim extraction: every priced line transcribed exactly as written, with each index, differential, and adder kept as its own component.
Linked to Atlas: every supply point, counterparty, spec, and index series becomes a door into the terminal, company, or benchmark behind it.
Benchmarked against the market: each formula laid component by component against the Mills canonical spot-to-rack build for that city and spec.
Negotiation ready: negotiable levers (RIN credits, adders, lower-of structures, auto-renewal and take-or-pay clauses) are called out, with a counteroffer column for the deal you'd rather have.
Private by design: contracts live in a private library and content is never logged.
