Contracts say one price. Invoices say another. We find the difference.

Problem

Every contract has fine print. Most invoices are never checked against it.

Enterprises typically lose 2-5% of supplier spend to contracts that are mis-billed or under-leveraged. Volume tiers, indexation clauses, rebate thresholds, rate-change cutover dates — pricing rules that read as one paragraph in a contract but apply across tens of thousands of invoice lines — routinely go unchecked, because nobody re-derives that arithmetic by hand every month.

Today's approach

Manual or periodic review

A spot check might sample a handful of high-value invoices once a year. The rest goes unexamined, month after month. Numbers are plausible but not reproducible, and there's no way to check the reasoning behind them.

With ReliaParse

Continuous, defensible, evidence-grade

Checks every invoice line against every applicable contract rule, every month. Every finding includes the contractual evidence and the calculation behind it — outputs ready for procurement and finance to action directly with suppliers.

Use cases

Questions your contracts should answer. We make them answerable.

01

"Do we even have a contract with them — and what did we agree?"

Every supplier, every document, one view of what's actually in force.

02

"Why is this contract still active?"

Superseded amendments, replaced price lists, duplicates, things that should have died years ago — flagged, with the paper trail.

03

"Which of our contracts would hurt us in a downturn?"

Every clause compared against your own standard: payment terms, auto-renewals, indexation, liability. A risk map, not a reading assignment.

04

"Are we being billed what we agreed?"

Every invoice line recomputed from the contract.

05

"What are we owed that we never collected?"

Rebate tiers reached, compensation clauses triggered, credits earned — and never claimed.

06

"Is anything about to renew or expire without us noticing?"

Notice windows and auto-renewals, tracked before they close.

Approach

Open research problems we're solving

Pillar I

From contract language to executable rules

Commercial clauses are a compilation problem. We study how language models can translate pricing terms into formal, human-verifiable rules, and where that translation fails. Extraction is probabilistic, execution is deterministic, and the boundary between the two is the core design question of the system.

Pillar II

Record linkage without shared keys

Invoice lines rarely reference the agreement that governs them, or name the product the way the contract does. Matching them is entity resolution under noisy data, at both the supplier and the product level. Our linkage models output calibrated match probabilities, and we study when a link is strong enough to justify a verification claim.

Pillar III

Calibrated uncertainty in reasoning

Most LLM systems cannot tell you how sure they are. We develop methods for calibrated confidence in zero-shot data extraction and reasoning, so every finding carries a defensible probability and weak evidence yields cannot verify rather than a guess.

FAQ

Questions we hear from potential design partners.

Is ReliaParse a product I can buy today? +

Not yet. We’re working with a small number of design partners to validate this on real contracts and invoice data before general availability. Early partners get hands-on access and a direct say in what we build next.

What data do you need? +

Your contracts (or the relevant pricing sections) and your invoice or billing history for the same supplier relationship. We don’t need your whole document archive — just the commercial terms and the bills.

Do we need to change our systems to use this? +

No — it runs alongside your existing payments and operational data. Nothing to migrate, nothing to replace.

How does data security work? +

It can run inside your own environment, so your data doesn’t need to leave your systems. We work within whatever data handling arrangement you require, and we’re happy to sign a DPA before any documents are shared.

Why not just point ChatGPT at our invoices? +

Because “probably right” isn’t good enough when the output is a dollar claim against a supplier. An LLM can misread a tier threshold or invent a missing rate and sound equally confident either way. We use deterministic, auditable arithmetic for every number we report — LLMs help us read contracts faster, but they never get the final say on a dollar figure.

We're looking for design partners.

If you manage supplier contracts with volume tiers, rebates, or indexation clauses — and suspect (or know) some of that isn't being billed correctly — we'd like to run your data through this and show you what we find, at no cost, in exchange for your feedback.
