  • Instant download from Gumroad after checkout

  • Checks totals, tax lines, dates, currency and duplicates
  • Writes invoices and line items to Excel/CSV (skill) or Google Sheets (n8n)
  • Puts anything odd on a review list with the reason

Tools and costs you'll need

Third-party costs are paid to those providers, not to us.

Test report

Re-run by the Oarsman QA gate on 2026-11-01: skill scripts 34/34, robustness 2/2, n8n workflow 30/30 on a fresh n8n 2.45.6 with OpenAI, Google Sheets and email mocked. Real public PDFs (sample invoice, rotated, password-protected, scanned, 22-page non-invoice): no wrong document reached ok. Not tested: reading accuracy of a real AI model on real invoices, photos or handwriting. Not accounting or tax advice.

Known limits

  • AI reading accuracy on real documents not yet measured (the model was mocked in tests).
  • Blurry photos and handwriting are where misreads happen; check the review list.
  • Data entry help, not accounting or tax advice.

What's AI here, and what isn't

This is an AI agent: it uses an AI model to read, sort, score or draft. It runs in your own accounts. Anything it would send outside your business waits for your approval unless you choose otherwise, and it never needs your passwords. Our AI disclosure.

Is Invoice & Receipt Extractor tested?

Re-run by the Oarsman QA gate on 2026-11-01: skill scripts 34/34, robustness 2/2, n8n workflow 30/30 on a fresh n8n 2.45.6 with OpenAI, Google Sheets and email mocked.

How do I get Invoice & Receipt Extractor?

It costs $29 on Gumroad: press "Get it" to buy it there. Refunds within 14 days.

Who reads the documents?

An AI model: Claude when you use the skill, OpenAI (your own API key) in the n8n workflow. Scripts then check the arithmetic, dates and duplicates. Models can misread, so check the review list and spot-check new suppliers.

Does it work with scans and phone photos?

Yes, the model reads them visually. Blurry photos and handwriting are where misreads happen; the totals check catches most number misreads.

Does it post to my accounting software?

No. It fills a spreadsheet or Google Sheet. It is data entry help, not accounting or tax advice.

What does the n8n version cost to run?

Your n8n plan plus one OpenAI call per document on your own key. We don't quote OpenAI prices; check theirs.
