What is a WooCommerce Checkout Page, and How does It Work?
A WooCommerce checkout page is an integral part of your online business that serves as the final step in the shopping process. This is where customers provide all the necessary information to complete their purchase.
Customers who click Proceed to Checkout are taken to the checkout page. This page is a form filled with various fields where customers enter their billing and shipping details. Some fields are mandatory and must be filled in for the transaction to proceed. The page also provides options for different payment methods, such as credit cards or digital wallets like PayPal, depending on how you’ve configured your store’s settings.
Additionally, if your online store offers shipping, the checkout page will display available shipping options and their corresponding costs for the customer to choose from. The page usually has a review section as well, allowing customers to verify their order details, including the products, quantities, and total price. Extra features may be included, such as coupon code fields, checkboxes for terms and conditions, or a section for order notes.
The system validates the entered information after all the required fields are filled in and the Place Order button is clicked. The chosen payment gateway will handle the payment process if everything is in order. Once the payment is confirmed, the customer receives an order confirmation both on the screen and via email. The details of this order are then stored in your WooCommerce admin panel for your later review and action.
