Magento 2 Link Guest Orders to Customer Account

Magento 2 Link Guest Orders to Customer Account

Product specification

Link Orders is a Magento 2 extension developed by PIT solutions which automatically assigns guest orders to the existing customer account with the same email address during customer registration from both frontend and backend.

Features

  • During customer registration, it checks if any guest order exists with that email address and if exists then it assigns that to the customer account.
  • Link the guest orders placed by registered customers also to customer account.
  • Automatically set default shipping and billing addresses to customer.
  • Allows configuring a follow-up email for guest orders which can ask customers to register.
  • Enable/ Disable the extension.
  • Enable/ Disable the follow-up email in extension.
  • Access control for admin users.
  • All guest orders created with the customer email will be mapped to the customer when creating customer from frontend OR backend.

Installation

To install the Link Guest Orders to Customer Account Extension for Magento 2, follow the steps below.

1) Download the extension.

2) Access your web server directories and unzip and upload the content of the zip file to app/code/Pits/LinkOrders directory.

3) Run the following commands from the SSH terminal of the server to complete the installation.

  • Enable the module - php bin/magento module:enable Pits_LinkOrders
  • Update the database schema - php bin/magento setup:upgrade
  • Generate and pre-compile classes - php bin/magento setup:di:compile
  • Deploy static files - php bin/magento setup:static-content:deploy
  • Clear the cache – php bin/magento cache:flush

Link Previous Guest Orders to Registered Customers 

After installing and enabling the extension in store configuration, run the following CLI command from project root folder to associate previously placed guest orders with registered customer accounts. 
php bin/magento pits:link-guest-orders

This command will automatically: 

  • Identify guest orders where the email matches an existing customer. 
  • Assign the order to the corresponding customer account. 
  • Convert the order from guest to customer. 

Recommended for Large Customer Databases

If your store contains more than 5000 customers, it is strongly recommended to execute the command in batches to avoid high memory usage and improve performance.

Use the start and end parameters to process customers within a specific Customer ID  range.

Example: 
php bin/magento pits:link-guest-orders --start=1 --end=5000

This command processes customers with Customer ID from 1 to 5000.

For the next batch, increment the range: 
php bin/magento pits:link-guest-orders --start=5001 --end=10000

A batch size of 5000 customers is considered a safe and stable value for most environments. 

Running Without Parameters

If the command is executed without the start and end options: 
php bin/magento pits:link-guest-orders

All customers will be processed without any limit. 
This is suitable for small to medium-sized stores but not recommended for large databases.

Before executing the command, please ensure the following:

  • Perform a complete backup of the database. 
  • Test and validate the command in a staging environment prior to production execution.
  • Schedule the execution during off-peak hours to reduce potential server load.
