Every figure traced to a document.

1. 01

   Upload the invoice.

   Start with the invoice you are questioning. PDFs, scans and photos are all accepted.

2. 02

   Add the evidence.

   Add the documents that say what the price should have been: the quote, contract, rate sheet, pricing notice, delivery receipt, BOL or a prior invoice.

3. 03

   Know what you owe.

   Every relevant charge is compared to your documents. You get the evidence, the dollar impact, a downloadable report and a drafted response email.

1. 01Validation

   We confirm the invoice is readable, identify the vendor and invoice number, and check that the documents you uploaded are relevant to it. If something essential is missing, you are told before analysis continues.

2. 02Extraction

   Line items, quantities, units, unit prices, taxes and totals are read from the invoice. Prices, effective dates, terms and quantities are read from your supporting documents. Every extracted value keeps a reference to its document and page.

3. 03Comparison

   Each invoice charge is matched to the evidence that governs it. Comparisons are made on like-for-like terms: the same unit, the same quantity basis and, where it matters, the same effective date and time.

4. 04Calculation

   Where a difference exists, the financial impact is calculated arithmetically from the extracted values - per-unit difference multiplied by quantity - and shown with the formula.

5. 05Report and response

   You get a downloadable report containing every finding with its evidence, plus an editable email drafted to raise the issue with the vendor in neutral, factual language.

Verified

The invoice matches your documents on this charge.

Possible discrepancy

The invoice differs from your documents, but a legitimate explanation is plausible and not ruled out.

Likely discrepancy

The invoice differs from your documents and the documents do not offer an explanation for the difference.

Insufficient evidence

A comparison cannot be made without an additional document.

Needs human review

The documents conflict, or the interpretation requires a judgement we will not make for you.

A difference is never reported as a billing error on its own. Where freight, margin, taxes, a timing change or a contracted charge could account for it, that is stated in the finding.
