Checkout flow

The checkout flow is the process of buying the items in the shopping cart. To buy products, the customer should provide additional details, such as the delivery address, and also make the payment using a credit card or some other means of payment. Checkout flow facilitates this data collection and collects the payment.

Checkout flow has two main parts:

1. User Interface: Showing order information to the end customer, collecting information, such as delivery address, and collecting the payment. This is done through the checkout flow pagetype and templates.
    
2. Business logic: Creating deliveries and communicating with third party systems, such as ERP systems if required, and calculating delivery costs, VAT and order grand total. This is done through the pricing rules plugin.

Changing the default checkout flow

To change the user interface, simply use a different checkout flow template (edit the checkout page in the Websites area and go to the Settings tab). You can have multiple checkout flows in the same website.
