Automatic invoice detection & reminder creation with Gmail & Google Tasks

This workflow contains community nodes that are only compatible with the self-hosted version of n8n.

Who is this for?

This workflow is for anyone who receives invoices by email and wants to stay on top of payment deadlines without manual tracking.

What problem is this workflow solving?

Invoices often get buried in your inbox. This workflow uses AI to find them, extracts key details, and adds a task to remind you to pay before it’s overdue.

No more missed payments. No more manual tracking.

How it works?

1. This workflow is triggered on a schedule (By default, every hour). 2. It checks your Gmail inbox for unread messages. 3. Each email is passed to an AI agent (using OpenAI), which decides whether it’s an invoice. 4. If an invoice is found: - A task is created in your Google Tasks with the payment reminder and due date. - The email is labeled (for tracking) and marked as read. 5. If not an invoice: - The email is skipped (no action taken).
