Automatic Invoice Detection & Reminder Creation with Gmail & Google Tasks

This workflow automates invoice management by triggering hourly to check your Gmail inbox for unread emails. An OpenAI-powered AI agent analyzes each email to determine if it's an invoice. If confirmed, it extracts key details like due dates and creates a reminder task in Google Tasks. The email is then labeled 'Invoice' and marked as read for easy tracking.

Benefits include eliminating missed payments, reducing manual inbox monitoring, and ensuring timely reminders without effort. It's ideal for freelancers, small businesses, or anyone handling frequent invoices via email, saving hours weekly on organization.

Customization options allow adjusting the AI prompt for specific invoice formats, changing labels, or modifying schedules. Requires self-hosted n8n with Gmail, OpenAI, and Google Tasks credentials, plus a 'Invoice' Gmail label.
