Diference between Date and Due date

When we consult billing listings or economic reports we see that the concepts of date and expiration constantly appear, they may seem similar but they entail large differences.

IN THE LIST OF PRODUCTS SOLD PDTES. PAYMENT

The Date refers to the date on which the debt was generated.
Instead the due date refers to the date when the debt  will take place.
E.g:

If today (01/08/2019) i make a reservation for tomorrow. The date would be 01/08/2019 instead the due date will be 02/08/2019.


With the payments happens the same. If i pay a booking for the next thursday, the date of the payment will be 01/08/2019 but the due date will be 08/08/2019
