Automate Stripe Invoices with n8n & DocuPotion PDF

Transform every Stripe payment into a professional, branded invoice PDF that lands in your customer's inbox automatically. This n8n workflow eliminates manual invoice creation by connecting Stripe webhooks directly to DocuPotion's PDF generator and Gmail, replacing Stripe's basic receipts with polished documents that match your brand.

What this workflow does

This automation creates a seamless four-step process that runs every time a payment succeeds:

• Stripe Charge Succeeded: Listens for the charge.succeeded webhook from your Stripe account to trigger the workflow instantly
• Prepare Invoice Data: Extracts customer name, email, billing address, payment amount, and currency from the Stripe payload, generates an invoice number from the charge ID, and converts cents to major currency units
• Generate PDF Invoice: Sends prepared data to DocuPotion using your custom template ID, which renders merge fields and returns a professional PDF as a binary attachment
• Email Invoice to Customer: Automatically delivers the branded PDF invoice to the customer's billing email via Gmail

Use cases

Perfect for SaaS companies processing subscription payments, e-commerce stores needing branded receipts, digital agencies billing clients, coaches selling services, or nonprofits managing donations. Anyone using Stripe who wants to replace plain-text receipts with professional invoices will benefit from this automation.
