To implement scheduled orders, you must add the Scheduled Order – Checkout widget to the checkout page you are using (either Checkout Layout or Checkout Layout with GiftCard). This widget presents UI controls to the shopper that capture the schedule information for a scheduled order, including a name for the scheduled order, the start and end dates, the frequency, and the option to suspend the scheduled order.
Also on the checkout layout, make sure you are using the latest version of these widgets:
Order Summary – Checkout widget. The latest version of this widget toggles the Place Order button to a Schedule Order button when the shopper selects the option to create a scheduled order.
Payment Details widget. The latest version of this widget disables the credit card payment option when the scheduled order checkbox is selected. Scheduled orders must be paid for via the invoice payment gateway, see Configure an invoice payment gateway for scheduled orders for details.
Payment Gateway Options widget. The latest version of this widget disables the Cash and PayU payment options when the scheduled order checkbox is selected.
Gift Card widget. The latest version of this widget disables the gift card payment option when the scheduled order checkbox is selected.
