How to Dynamically Change Billing Address in Magento 2

In this blog post, I have provided a complete solution to dynamically change billing address in Magento 2.

The billing address defines a physical location/address where the invoices or bills of the online orders are sent to the customers. In special cases, you may require to dynamically change the billing address of specific customers after placing the orders on your Magento 2 store.

Suppose you are running an online store on Magento 2 and have tied up with another company to deliver some essential products to their employees. In that case, you may require to dynamically change the shipping address of such orders to that of the company where you want to send the invoices. This process can be made easier if your e-commerce platform allows for the management of multiple shipping addresses, as you can easily add and switch between different addresses for your orders

To do that, you might need to define customers’ attributes and change the billing addresses of customers having specific attributes. You can refer to the programmatic solution provided here for that.

Steps to Dynamically Change Billing Address in Magento 2

In order to add dynamic billing address to orders in Magento 2, you may first require to register a new module by creating registration.php file at app/code/Vendor/Module/ directory and adding the following code:

app/code/Vendor/Module/registration.php

<?php

use Magento\Framework\Component\ComponentRegistrar;

ComponentRegistrar::register(
    ComponentRegistrar::MODULE,
    'Vendor_Module',
    __DIR__
);

app/code/Vendor/Module/registration.php

<?php

use Magento\Framework\Component\ComponentRegistrar;

ComponentRegistrar::register(

ComponentRegistrar::MODULE,

'Vendor_Module',

__DIR__

);

After registering and creating the module, you need to create a custom event that can be dispatched when the customer places an order. Create an events.xml file at app/code/Vendor/Extension/etc/ with the following code:

app/code/Vendor/Module/etc/module.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <module name="Vendor_Module" setup_version="1.0.0">
    </module>
</config>

app/code/Vendor/Module/etc/module.xml

<?xml version="1.0"?>

</module>

</config>

Finally, you need to add an obersever that dynamically changes the customer’s billing address once the order is placed. Create a AfterPlaceOrder.php file at app/code/Vendor/Extension/Observer/ directory with the following code:

app/code/Vendor/Extension/etc/events.xml

 <event name="checkout_onepage_controller_success_action">
        <observer name="vendor_extension_order_place_after "
                  instance="Vendor\Extension\Observer\AfterPlaceOrder"/>
    </event>
