INVOICE PROCESSING
Track Invoice PDFs in Drive and Catch Renewal Price Jumps
Watches a Google Drive invoices folder, extracts the vendor and total from each new PDF, updates a per-vendor price history in Airtable.

What it does
Many teams archive invoices as PDFs in a shared Drive folder rather than an inbox. This workflow watches that folder, reads each new invoice PDF, and maintains a running price history per vendor in Airtable. When a vendor's renewal total exceeds its previous recorded amount, it posts the comparison to Microsoft Teams so the increase is reviewed before the next payment goes out.
When to use it
Reach for this when invoices are filed in Google Drive and your team coordinates in Microsoft Teams, and you want a lightweight, visible price-history ledger in Airtable without standing up a database.
How it works
- 1A new file is added to the watched Drive invoices folder.
- 2An OpenAI step extracts vendor name, total, and billing term from the PDF.
- 3The flow looks up the vendor's last recorded total in Airtable.
- 4A logic step flags the invoice when the new total is higher than the prior term.
- 5The Airtable record is updated with the new amount and date.
- 6A Microsoft Teams message posts the vendor and the price jump for review.
