Orders placed using Woocommerce are kept in the WordPress database.
The specifics of the order (such as the customer’s information, the product information, and the order total) are stored to the WordPress database as a new “order” post type when an order is placed on a website that uses Woocommerce.
From the WooCommerce > Orders section of the WordPress admin panel, you can access and manage this data.
Each order may be readily seen, modified, and handled from this screen and has its own own post ID. Additionally, for usage in other systems, the order details can be exported as a CSV file.
