In the receivables, in the list "Outstanding Invoices", timeSensor LEGAL marks invoices for which you should send a reminder with a grey point. This entry explains how timeSensor LEGAL calculates whether or not to display a grey point.
The starting point for the first reminder is the invoice date. You will find this date at the top of the invoice entry. The following screenshots show you how to change the invoice date in an existing invoice, if necessary:
The starting point for subsequent reminders is the date of the last reminder. Provided the next reminder is not outstanding, you may modify the reminder status. For example, you can change the date of the previous reminder or delete the last reminder.
The calculation is based on the current preferences for reminders of the Statement scheme assigned to the invoice. According to these preferences, a defined number of days will be added to the date of the invoice (or the date of the last reminder):
Finally, a tolerance period is added. The default period is five days. Note that if you wish to change this tolerance period, you will need to contact the hotline to make the modification. This specific parameter is not implemented in the GUI.
The short answer to the question is therefore: timeSensore LEGAL will display a grey point when the date of invoices (or the date of the last reminder) plus the payment deadline according to the current preferences for reminders in the Statement scheme assigned to the invoice plus tolerance is smaller than the current date.
