Auto-Send PDF Invoices on Stripe Payments via Gmail

This n8n workflow streamlines invoicing by triggering on successful Stripe payment intents. It captures payment details like amount, customer info, and ID via webhook, normalizes the data, generates a customizable HTML invoice template, converts it to PDF, and sends it directly via Gmail with a confirmation message.

It saves hours weekly on admin tasks, reduces errors, and ensures compliance with automated records.

Ideal use cases: Freelancers sending service invoices, SaaS platforms confirming subscriptions, e-commerce stores for one-off purchases, or agencies billing clients. Customize easily for logos, taxes, or multi-currency support. Setup requires Stripe webhook endpoint and Gmail OAuth—live in minutes.
