Automate Invoice Extraction from Google Drive with GPT-4o & Postgres

Revolutionize Your Invoicing with Automated Invoice Extraction from Google Drive

Streamline your finance operations with this intelligent automation workflow that seamlessly extracts invoice data from Google Drive, identifies duplicates, and efficiently processes these into your Postgres database. Leverage the power of OpenAI's GPT-4o to transform how you manage invoices.

What This Workflow Does

• Automated File Monitoring: Every hour, this workflow scans a specific Google Drive folder for new invoice images.
• Intelligent Data Extraction: Downloads new files and submits images to OpenAI's GPT-4o for detailed invoice data extraction into structured JSON.
• Data Verification and Processing: Verifies the extracted data for accuracy and routes any invalid entries to a dedicated failed path for further review.
• Duplicate Check and Management: Cross-references invoices through Postgres for duplicates by checking vendor names, invoice numbers, and totals. Files identified as duplicates are moved to a designated folder in Google Drive.
