Know what you promised before you bill or change a price.

Contracts, amendments, price letters and forwarded emails as PDF or text, a customer list, and invoice lines as CSV, XLSX or JSON. You see the field mapping before anything is stored.

No integration and no billing-system access. Nothing leaves the workspace you upload it to.

Rules-based extraction finds prices, holds, exceptions, amendments and end dates, and keeps the quoted clause with each one. A clause is tracked automatically only when it is found word for word and nothing in it is ambiguous.

What it cannot read exactly (1 item in the sample) is held for a person, not guessed.

Each finding opens onto the invoice line, the commitment in force on that date, the exact source words, and the arithmetic. The same inputs always give the same result.

Money billed above or below the commitment is shown as a calculated amount, never as recovered. A proposed change is replayed on 16 recorded lines: who moves, who is protected and by which clause. It is history, not a forecast.

Release checks end in SAFE, REVIEW or BLOCK, and stay advisory until someone records a decision. A claim built on a reading nobody has reviewed cannot be approved automatically.

Recovery cases follow a finding through review, verification and resolution. The ledger is append-only: potential, approved, promised and recovered are separate numbers, and proof packs and share links let someone outside check the work.
