🧾 Create or find Stripe customers and automatically generate invoices

Description

Save hours of manual billing work with this Stripe automation workflow!
Designed for entrepreneurs, SaaS founders, and online business owners, this template checks if a customer already exists in Stripe based on their email. If no customer is found, it automatically creates a new one, generates a draft invoice, adds a product line item using a Stripe Price ID, and finalizes the invoice — making it ready for payment.
This workflow helps ensure clean customer data and efficient billing without manual input.

How it works

• Search Stripe for an existing customer based on the provided email address.
• If no customer is found, create a new one in Stripe automatically.
• Generate a draft invoice associated with the customer.
• Add a line item to the invoice using a Stripe Price ID.
• Finalize the invoice to make it ready to send or collect payment.

Set up steps

1. Stripe account setup:

   • Ensure you have a valid Stripe account.
   • Create a restricted Stripe API key with permissions to read and write Customers, Invoices, and Invoice Items.

2. Connect Stripe to n8n:

   • Set up an HTTP Basic Auth credential in n8n using your Stripe secret API key.
   • No username is needed; the API key goes into the password field.

3. Customize dynamic data:

   • Replace the sample email (test@example.com) with your real dynamic customer email input.
   • Replace the example Price ID (price_fromStripeDashboard) with your actual product Price ID from the Stripe dashboard.

4. Test your workflow:

   • Manually trigger the workflow inside n8n to ensure customers and invoices are being created correctly.
   • Check your Stripe dashboard to confirm that new customers and invoices appear as expected.

5. Deploy to production:

   • Integrate this workflow with a real trigger (e.g., webhook, form submission) to automate the process live.

Troubleshooting

• Invalid API Key:
  Double-check that your Stripe API key is active and has the necessary permissions. Test it by making a simple API call manually if needed.

• Invoice Creation Fails:
  Make sure you are using a valid Price ID from Stripe. The price must be active and available for the correct product.

• Customer Not Found Error:
  If the search fails due to formatting issues, ensure emails are valid and the query syntax matches Stripe’s customer search format.

• Authentication Errors:
  If authentication fails, ensure you have selected HTTP Basic Auth in the HTTP Request nodes and left the username field empty.

Stripe prerequisites

• You must have at least one active Price object created in your Stripe dashboard.
• Your Stripe account must be live or have access to test mode if you’re working in development.
• Ensure your account has API access enabled for Customers, Invoices, and Products.
