Automated Invoice Processing & Validation Workflow

This n8n workflow automates the end-to-end process of handling, validating, and storing invoices received via email, streamlining accounts payable operations. The process begins by triggering on scheduled emails, extracting invoice data from attached files, and using AI-powered language models for text extraction and validation. The workflow then organizes invoices into a structured folder system on Google Drive, categorizing by month and day, and updates a master sheet with relevant invoice details. Additional steps include generating unique invoice keys, validating data accuracy, and sending notification emails. This automation enhances efficiency, reduces manual effort, and ensures accurate record-keeping for invoice management.
