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.
