How WooCommerce attach pdf invoice to email?

We know by now, WooCommerce generates transactional emails automatically. However, it doesn’t create invoices. We are using the Challan plugin for that.

One great feature Challan offers out of the box is the ability to work with Woo Commerce’s transactional email system to automatically attach the pdf invoices to order confirmation emails or to the email of your choice.

Let’s check how this process works.

Let’s begin with installing Challan. Go to Plugins>>Add New from your WordPress dashboard and type in Challan in the search box.

Install and activate the plugin. Your job is pretty much done. Challan will now automatically generate invoices and attach them to the order confirmation email from the very next order.

Let’s find out if that is true by creating a custom order. Go to WooCommerce>>Orders and then click on the Add new order button.

First, change the order status to “processing.”

Now, click on the small pen icon to change the billing address and put in the information for our demo customer.

It’s time to start including some items/products in this purchase. To include products in your order, simply go to the items section and add items by clicking the Add Items button.

A new window will pop up, you need to search and add your products there. Once you add some items, it will appear on the page with the total amount.

In order to finish the process, you should now click on the Create button from the panel on the right. With the assistance of Challan, your shop will now generate a WooCommerce invoice automatically and attach it to the new order email.

Here’s how it may look in the customer’s email. You can also see an invoice attached to the email.

By the way, Challan creates a dedicated panel for you to download invoice and other documents manually, as can be seen in the image below.

Challan email settings

Even though Challan enables the necessary settings to WooCommerce attach pdf invoice to email out of the box. However, you can enable more options from the settings.

You can allocate additional emails to attach the invoices. Let’s have a look.

As soon as you install Challan, it will have its own menu in the WordPress back panel. Hover over to click the settings option.

Then jump to the general settings. There you see options for enabling invoice generation, and WooCommerce attach pdf invoice to email.

With the free version of Challan, you can enable the following transactional emails to attach your invoice.

  • New Order
  • On Hold Order
  • Processing Order
  • Refunded Order
  • Completed Order
  • Customer Invoice

However, the premium version has greater email support and the ability to include packing slips with WooCommerce invoices.

Are customers not receiving your emails?

WordPress WooCommerce uses PHP mail to send transactional emails. This means that WordPress is sending the transactional emails from your hosting server.

For the most part, WordPress hosts do not have their servers configured properly to enable email sending. This means that there is a chance that your emails will not be sent or will be delayed in transit.

In addition, email service providers like Google Mail and Yahoo are waging a never-ending war against spammers in an effort to protect their users’ inboxes. When they receive an email, one of the first things that their servers do is perform a check to determine whether or not the email actually originated from the location that it claims it did.

Lacking proper authentication may result in the email being deleted or sent to the spam folder. Therefore, your customers will not receive the WooCommerce invoice if they are not receiving the emails.

Now, then, what can you do about it?

Installing an SMTP plugin is something that we recommend. SMTP, which stands for Simple Mail Transfer Protocol, is the standard protocol for sending emails.

By employing authentication methods that are mutually accepted by email service providers, properly configured SMTP increases the likelihood that sent messages will be received by their intended recipients. While SMTP plugins are useful, they do require some technical configuration before they can be used.

Installing the free plugin WP Mail Logging is a quick option. This plugin is great because you don’t have to change any settings.

We have tested this plugin before writing about it, and we noticed an immediate improvement in email delivery.

Wrap up

Invoices are significantly important as they serve multiple purposes, including legal protection, tax filing, etc. In addition, they can also act as a brand tool to impress your customers and earn their trust.

Moreover, invoices can increase the chance of repeat purchases if you create the templates effectively.

We have learned how WooCommerce attach pdf invoice to email and what plugin you need for the task. Hope you will start sending out invoices for your next orders using the methods we have shown here.
