This advanced n8n workflow automates the entire invoice intake process using email triggers, PDF parsing via LlamaParse, and AI data extraction. It listens for incoming invoice emails in Gmail, extracts invoice details with the help of LlamaParse, and further refines information using a language model. The extracted data is then organized into a Google Sheet for reconciliation purposes, and processed invoices are tagged with labels to prevent duplication. This workflow is ideal for streamlining accounts payable, reducing manual data entry, and ensuring efficient invoice management in a business environment.
