For shippers, not carriers

Your freight bill says one thing. Your contract says another.

FreightSigil checks carrier invoices against your rate agreements and shows exactly where the numbers don't match — with the contract clause, the calculation, and the evidence to prove it.

No integration required for your first test. Send an invoice and a rate agreement.

Reads the invoice and rate card, proposes the fields.

CODE

Runs the deterministic calculation — no model decides a dollar figure.

EVIDENCE

Every finding cites the exact contract clause it's checked against.

YOU

Approve before anything is sent to a carrier as a claim.

Freight audit is a real category. The mid-market is left out of it.

Enterprise freight audit firms exist and process real volume — but they're built for shippers spending $50M+ a year, with custom pricing and multi-month onboarding. Below that, most finance teams are down to a spreadsheet and a hunch.

Rate mismatches

Contracted caps that quietly don't make it onto the invoice.

Duplicate charges

The same charge, same line, billed more than once across a busy invoice run.

No time to check

A lean finance team can sample a few invoices a month. The rest get paid on trust.

Test it on your own invoices, free

Send a recent invoice and your rate agreement. No integration, no login, no obligation — and we won't contact a carrier without your written approval.

From invoice to claim

Six steps, and nothing skips the evidence.

01

Invoice

The carrier's charges, read line by line.

02

Contract

Checked against the specific rate agreement version active on the shipment date.

03

Calculate

Plain arithmetic against the contract. Same inputs, same answer, every time.

04

Evidence

Every finding gets an Evidence Assurance Score before you see it.

05

Approve

Nothing becomes a claim without a named person confirming it.

06

Recover

A dispute-ready package, tracked through to the credit that lands.

Not every finding is equally certain. The score says so.

The score is the plain average of six named dimensions — never a bare model-confidence number. Anyone can recompute it from the finding's own evidence object.

  • Contract authoritydimension
  • Shipment evidencedimension
  • Invoice integritydimension
  • Calculation reproducibilitydimension
  • Temporal validitydimension
  • Evidence completenessdimension
score = round(sum(dimensions) / 6)

Flat pricing. No cut of what you recover.

Freight audit firms often take a share of what they find. FreightSigil is planned as a flat monthly fee by invoice volume instead — self-serve billing isn't live yet, so these are the intended tiers, not an active checkout.

What's actually protecting your documents

Stated plainly, matched to what's built today.

Tenant isolation

Every record is scoped to your organization at the database query level.

Hashed API keys

Keys are stored only as salted hashes — the raw key is shown once, at creation, never again.

Hash-chained audit log

Every state-changing action is appended to a signed, tamper-evident chain.

Role-based access

Owner, analyst, and read-only roles, enforced on every write.

No guessed findings

Insufficient evidence produces a held result, never an invented number.

Errors that don't leak internals

Failures return a plain message — never a stack trace or database detail.

Send us one invoice and one rate agreement.

We'll show you exactly what doesn't line up — with the evidence, not just a guess.
