In WordPress, the Subscriber and Customer roles are two different built-in user roles with different capabilities and purposes. The Subscriber role is the lowest level of user role in WordPress. Subscribers are users who have registered on a website, but they have very limited capabilities. They can only view content on the site and update their own profile information. They cannot create or publish content, comment on posts, or perform any administrative tasks. The Customer role, on the other hand, is a user role that is used by WooCommerce, which is a popular e-commerce plugin for WordPress. Customers are users who have made a purchase on a website that has WooCommerce installed. They have the ability to view and manage their own orders, add and edit billing and shipping information, and view product downloads. However, they do not have any administrative capabilities or access to the WordPress dashboard. In summary, while Subscribers are simply registered users with limited capabilities, Customers are registered users who have made a purchase on a website with WooCommerce installed, and they have access to additional e-commerce related capabilities but no administrative access to the WordPress dashboard.
