Automate invoice data entry from email to spreadsheet

Zapier extracts invoice details from email attachments and writes them to a Google Sheet or Airtable before you open the file.

Every invoice lands in your sheet with vendor, amount, date, and invoice number extracted and formatted.

1. 1

   Test with ten real invoices

   Forward historical invoices to the trigger email. Check that vendor names and amounts match the source.

2. 2

   Set up the fallback notification

   A failed extraction should not silently skip an invoice. Route failures to a person.

3. 3

   Run it in parallel with manual entry for two weeks

   Compare the Zap output to what you would have entered. Fix the parser before you rely on it.

Design a Zapier workflow that extracts invoice data from email attachments and writes it to a spreadsheet.

Trigger:
- Gmail or Outlook: new email with attachment matching "invoice" or "receipt" in subject or filename

Steps:
1. Download the attachment (PDF or image)
2. Use OCR or a document parser (Zapier's built-in parser, or integrate with a service like Docparser or Parseur)
3. Extract: vendor name, invoice number, date, total amount, due date
4. Write a new row to Google Sheets or Airtable with extracted fields and a link to the original email
5. If extraction fails on a required field, send a Slack notification or email with the attachment for manual review

Show the Zap steps, the parser configuration, and the fallback logic for missing data.

OCR and parsers fail on non-standard layouts. Always route failures to a human review queue.
