AI automation · lab project
Invoices and receipts in. Clean, checked data out.
Finance teams still retype documents into spreadsheets. This pipeline reads them with AI, validates every number, and flags anything it isn't sure about. Pick a sample below and see what comes out.
Fictional sample document. Every company and number is made up.
Turn this invoice into data
Vendor, dates, line items, tax and totals, checked against a strict schema and ready for your spreadsheet or accounting tool.
Saved output from a real AI run
How it works
Built to be trusted with real money.
- 01
Document arrives
Uploaded, emailed to an inbox, or dropped in a shared folder. PDFs, scans and phone photos.
- 02
AI reads it
Claude extracts vendor, dates, line items, tax and totals — even from crooked or crumpled receipts.
- 03
Validated, not trusted blindly
Output must match a strict schema, totals are re-checked, and unclear fields are flagged for a human.
- 04
Lands where you work
A spreadsheet row, your accounting tool, or your own database — no retyping.
As a workflow
Same engine, running on your inbox.
The extraction also ships as an n8n workflow: invoices emailed to a finance inbox are processed automatically and land in a shared sheet, with a Slack summary for approval.
