Unpaid Invoice Reminder

Unpaid Invoice Reminder enables automatic notification for invoices that remain unpaid after a configurable interval. Scheduled actions trigger reminder emails at the frequency defined by the administrator for selected users. Each user can be enabled or disabled for reminders via a simple boolean setting in the invoicing configuration. Customer and vendor invoices are evaluated based on their payment status and reminder rules. All reminder emails are sent using mail features and recorded in the chatter for traceability. The module is lightweight and integrates cleanly with existing invoicing and mail workflows.
