How to Send Invoices Automatically After Checkout on Shopify

In the fast-paced world of e-commerce, customers expect instant confirmation of their purchase. If your team is manually emailing PDFs or, worse, waiting for customers to ask for a receipt, you are creating unnecessary friction. Automating your post-purchase documentation is one of the easiest ways to professionalize your brand and free up your support inbox.

This guide is for Shopify store owners who want to implement a set it and forget it system for digital paperwork. We’ll show you how to trigger an automatic invoice the second a customer hits the Pay Now button.

Quick Answer

You can send invoices automatically after checkout by integrating Order Printer Pro with your Shopify notification emails. Instead of sending a separate email, you simply add a Download PDF Invoice link to your standard Shopify Order Confirmation or Shipping Confirmation emails. This method ensures invoice automation works 24/7, providing customers with a branded, professional PDF at the exact moment they need it, without any manual intervention from your team.

What is Post-Checkout Invoice Automation?

Post-checkout automation is a workflow where a digital document (Invoice, Receipt, or Quote) is generated and delivered to the customer immediately following a successful transaction. This removes the need for manual invoice printing or separate email attachments.

Who Needs Automatic Invoice Delivery?

• B2B and Wholesale Sellers: Business clients require formal invoices for their tax records and accounting.

• International Brands: High-growth stores selling in regions like the EU where a "Tax Invoice" is a legal requirement.

• High-Volume Retailers: Any store that wants to reduce "Can I have a receipt?" support tickets.

Why Automation Matters for Shopify Stores

• 24/7 Customer Service: Customers get their documents instantly, even if they shop at 3 AM.

• Reduced Overhead: Saves your staff hours of manual "Save as PDF" and "Attach to Email" tasks.

• Professional Brand Image: Delivering a high-quality, custom invoice immediately builds buyer confidence.

• Compliance: Ensures you are meeting legal requirements for digital receipt delivery in real-time.

How to Set Up Automatic Invoices on Shopify

Step 1: Install Order Printer Pro

Start by installing Order Printer Pro. This app provides the hosted PDF links required for invoice automation.

Step 2: Customize Your PDF Template

Before going live, use the invoice customization tool to add your logo, brand colors, and tax information. This ensures the PDF the customer downloads looks exactly like your brand.

Step 3: Copy the Automated PDF Link

Inside the app, navigate to the Automated PDFs section. The app will provide a small snippet of code (a Download Link) that is unique to your store and the specific order.

Step 4: Add the Link to Shopify Notifications

Go to your Shopify Admin > Settings > Notifications. Open the "Order Confirmation" email template. Paste the link snippet into the email body—usually near the "View your order" button.

Step 5: Test the Flow

Place a test order on your store. Check your email inbox for the confirmation. Click the link to ensure it generates a perfectly branded automatic invoice PDF in your browser.
