A Second Overdue Payment Reminder is a type of correspondence sent by creditors to remind debtors of a payment that is past due. This reminder is usually the second contact from the creditor to the debtor after the initial invoice has gone unpaid. It typically includes a statement of the amount owed, the date the payment was due, and a reminder of the consequences of not paying the debt. There are two main types of Second Overdue Payment Reminders: Soft Reminders and Final Notice Reminders. Soft Reminders are more polite and less aggressive in tone, often asking for payment without threatening any consequences. Final Notice Reminders, however, are more confrontational and warn debtors that a more serious action may be taken if the payment is not made in a timely manner.
