This plugin is designed to simplify the process of creating new users/customers. It’s particularly useful if you receive client orders via phone or email and want to integrate these orders into WooCommerce for stock and order management. 
The plugin adds a checkbox at the end of the billing address form. When this box is checked, it creates a new user with the role “customer.” If an email is not provided, the plugin generates a unique one using your site’s domain as the email domain and the customer’s name as the local part (e.g., firstname.lastname@your-site.com). You have the option to customize this auto-generated email format.

By default, the newly created user does not receive any emails during account creation, though they will probably on order updates.
In the settings menu, there are options to: 
– Check the box by default 
– Send login credentials to the new customer
There are also additional options: 
– Update new customer information by default 
– Link customer orders 
– Define the user role individually 
– Set the user role for new customers 
– Customize the auto-generated email format 
– Edit the email subject for accounts created 
– Change the sender’s email address
Settings Menu: 
WooCommerce -> Add customer settings
Required Plugins: WooCommerce 4.7.0 or higher 
Required PHP extension: Intl
