Magento 2: How to Add Custom Text after Billing Address and Shipping Address in Invoice PDF?

Hello Magento Friends,

In this blog, we will discuss How to Add Custom Text after Billing Address and Shipping Address in Invoice PDF in Magento 2.

Invoices are legal proof given to customers for the items they have purchased from your store. Online store owners can send invoices through emails or in PDF format. Magento 2 Download Invoice PDF Extension helps to allow customers to easily download invoice PDFs whenever required from their My Account section.

The invoice contains information like order details, shipping address, delivery address, payment method, shipping method, invoice no., order no., date, etc. Apart from these details if you want to show additional information after billing and shipping address in the Invoice PDF, perform the below steps.

Steps to Add Custom Text after Billing Address and Shipping Address in Invoice PDF in Magento 2:

Step 1:  First, we need to create a “di.xml“ file inside our extension at the following path

app\code\Vendor\Extension\etc\adminhtml\

Then add the code as follows

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <preference for="Magento\Sales\Model\Order\Pdf\Invoice" type="Vendor\Extension\Model\Order\Pdf\Invoice"/>
</config>

Step 2:  After that, we need to create an “Invoice.php” file inside our extension at the following path

app\code\Vendor\Extension\Model\Order\Pdf\

And add the code as given below

<?php
namespace Vendor\Extension\Model\Order\Pdf;

use Magento\Store\Model\ScopeInterface;
use Magento\Sales\Model\RtlTextHandler;
use Magento\Framework\App\ObjectManager;
