The Automated Process Flow

1. Email Monitoring: Continuously scans Gmail for unread emails with PDF attachments
2. File Extraction: Automatically saves invoice PDFs to a designated Google Drive folder
3. AI Analysis: Leverages OpenAI's GPT-4o to intelligently extract key data points - date, description, amount
4. Data Structuring: Populates Google Sheets with formatted invoice information
5. Reference Creation: Links each spreadsheet entry back to the stored document

This entire process happens in the background, requiring minimal setup and zero ongoing maintenance.
