Overview

What it is

Invoices, receipts, and documents processed by hand come with errors, and the errors surface in your books weeks later. Extraction is a job AI does well, with a human review queue for the cases it flags.

We build extraction pipelines that read incoming documents, validate the data against your rules, file it in the right system, and route low-confidence items to a human. You get the speed of automation without giving up control over the numbers that matter.

Sounds familiar?
  • “Invoices, receipts, and documents are processed by hand, with errors.”
  • “We retype the same data between tools every single day.”

How it works

A fixed-scope path from spec to handover

You approve the spec, we build it, you see it run, you own it.

  1. Sample your real documents

    We start from your actual invoices, forms, or documents — not idealized examples — and define the fields that matter.

  2. Define validation rules

    What must always be true (totals match, vendor is known, dates are sane) and what routes an item to human review.

  3. Build the pipeline

    Extraction, validation, and filing into your accounting system, spreadsheet, or database.

  4. Human review queue

    Low-confidence items land in a review queue with the extracted data side by side with the source document.

  1. InputIncoming document (email, upload, scan)
  2. Step 1Extract fields with AI
  3. Step 2Validate against your rules
  4. Step 3File it — or queue for human review
  5. OutputData in your systems, errors caught before they land in the books
Illustrative flow. Your build is specified and demoed on your own process during the audit.

What you get

Named deliverables, not billable hours

Everything below is included in the fixed price and handed over with documentation and credentials.

  • Extraction pipeline for your document types
  • Validation rules agreed with you as acceptance criteria
  • Human review queue for low-confidence items
  • Documentation and ownership of every component
