Vendor W-9 Intake and Validation Agent

When a new vendor record appears, an agent emails the vendor for their W-9, reads the returned PDF, validates the TIN and legal name, and files a clean record.

How it runs

The automated pipeline, trigger to output.

  • LogicValidate TIN format against entity type and confirm signature
  • ActionWrite verified tax record back to NotionNotionNotion
  • OutputPost validation failures to Slack review channelSlack

What it does

Turns a raw new-vendor entry into a verified tax record. The agent requests a W-9, parses the uploaded form, checks that the legal name, TIN type, and signature are present and internally consistent, then writes a structured record and flags exceptions for a human.

When to use it

When Finance onboards vendors faster than anyone can chase paperwork, and you want W-9 collection and a first-pass tax-data review handled without a person reading every PDF.

How it works

  1. 1A new row in the vendor Notion database fires the trigger.
  2. 2The agent sends a branded W-9 request email via Gmail with a secure upload link.
  3. 3On reply, it reads the attached W-9 and extracts legal name, business type, and TIN.
  4. 4A logic check confirms the TIN format matches the entity type and the form is signed.
  5. 5Clean records are written back to Notion as "Tax Verified"; failures post to a Slack review channel with the specific reason.
