When customers place an order in your WooCommerce store, they automatically receive an order confirmation email. Adding a PDF invoice to that email improves clarity and provides a complete billing record in one place.

Automatic invoicing allows your store to generate and email invoices once payment is confirmed. This keeps your billing process consistent while reducing manual workload.

Here’s why automatically sending customer invoices matters:

• Improves customer experience – Buyers receive a clear billing document immediately after purchase.
• Maintains accurate records – Each electronic invoice is stored with the order for easy tracking.
• Supports tax and accounting requirements – Proper invoicing simplifies reconciliation and compliance.
• Saves administrative time – Orders move through the billing workflow without extra steps.
• Strengthens brand presentation – Professionally formatted invoices reflect your store’s credibility.
• Supports invoice printing – Customers can download or print invoices directly from the email.

If you’re looking for how to email invoices in WooCommerce, configuring automatic invoice generation within your store settings is the most efficient approach.

To automatically email invoice PDFs to customers after order completion, follow these steps:

Step 1: Install and Activate WebToffee WooCommerce PDF Invoices Plugin

• From your WordPress dashboard, go to Plugins > Add New Plugin.
• Search for “WooCommerce PDF Invoices” plugin by WebToffee in the search bar.
• Install and activate the plugin on your WordPress website.

After activation, the setup wizard will prompt you to enter your store details. These details appear on your invoices and form part of your electronic invoice layout.

Step 2: Choose WooCommerce Order Status to Automatically Send PDF Invoices

After activating the plugin, configure when WooCommerce should generate and attach the invoice PDF.

• Go to Invoice/Packing > Invoice from the WordPress sidebar menu.
• Switch on the Enable Invoice option.
• Choose a date for the invoice date.
• Choose Completed as the order status to create the invoice automatically.
• From the Attach invoice pdf in WooCommerce Email, choose the order status to automatically attach the PDF invoice.
• Enable the Show Print Invoice button for customers to let customers print invoices directly from the order email. This also allows them to print invoices from the order listing and order details pages.

Step 3: Choose an Invoice Number Format

Setting up a proper invoice number format helps you track and manage invoices efficiently.

• Choose a prefix and suffix for your invoice numbers (for example, INV or 2026).
• Define the invoice number length if you want padded numbers such as 0001 or 0100.
• Set the starting number for invoice generation.

• Click on Update Settings to save the changes.

A custom invoice number example could look like: INV-0002-2026

Once these settings are saved, WooCommerce will automatically generate the invoice and attach it to the order email when the selected order status is triggered. Customers will receive the invoice as a PDF attachment along with their order notification.
