Currently, PreOrder Now (PON) does not allow you to set a specific interval (e.g., two weeks) between the first and second or final payment.
The partial payment option was introduced to give your customers a more flexible way to manage their budgets while they wait for their preorder products to become available.
How It Works:
The second payment date is determined by the availability date of the preorder product.
The system automatically processes the second payment on the selected date, without requiring any manual intervention from the merchant.
This is why the calendar allows you to select a date for the second payment—ensuring the process is as seamless and automated as possible.
