If you want to remind a Client that there is an unpaid Credit Request on their account, you can send a Credit Request Reminder by navigating to an unpaid Credit Request and selecting 'Send Reminder'. This will open the Send Invoice Reminder panel, from where you can opt to send just a reminder, or resend the full Credit Request.
Sending a Credit Request Reminder.
Reminders can be automatically sent via email for unpaid Credit Requests after a set number of days have passed by navigating to System > Settings > Accounting Settings > General before enabling the ‘Automatic Invoice Reminders’ checkbox. The number of days that the automatic Invoice reminder is sent after is set via the ‘Automatic Invoice Reminders Delay’ field.
