WooCommerce One Page Checkout

One Page Checkout makes it possible to turn any page into a checkout page. It also makes it easier for your customers to buy from these custom checkout pages by displaying both product selection and checkout forms on a single page.
Customers can add or remove products from their cart and complete payment without leaving the page and waiting for a new page to load.
Checkout fields can also be displayed on a single product’s page, or you can add the field to custom landing pages for unique promotions. It’s easy to create a single page checkout, and once you do, it’s even easier for your customers to purchase the products on that page.
