Write payment reminders: three-stage dunning

What projectxy takes care of

• After the due date and a configurable grace period, the invoice appears in dunning as eligible for a reminder.
• Three levels – payment reminder, 1st reminder, 2nd reminder – with their own texts, deadlines and reminder fees.
• Reminder run: create reminders for all eligible invoices with one click, then print or send them by e-mail.
• The reminder shows the invoice amount, what has been paid, the open amount, fees and the new deadline – including GiroCode.
• Reminder history per invoice; whichever reminder is the latest can be withdrawn. Once the invoice is paid in full, the process ends.
