Streamlining the checkout flow
Depending on the features that you set up for checkout, you can omit steps in the
checkout flow.
If Invoice is the only available payment method and customers do not define billing addresses, you can omit the Payment step in the checkout process.
If you do not use confirmed delivery date functions, you can omit the Delivery step.
If you omit a step, the step is not included in both the standard checkout process and the order approval checkout process.
