Payment reminders and late fee notifications

**1. Purpose**

1. Automate and streamline timely payment collections, reduce manual follow-ups, automatically remind clients of upcoming or overdue dues, send late fee notifications, enforce finance discipline, and minimize revenue leakage via automated reminders.

2. Automated payment reminder workflows ensure bus company clients and vendors are notified before and after due dates, promoting prompt settlement with minimized human intervention.

3. Automator serves to escalate unpaid invoices by automating late fee notifications, support finance, and audit reporting for corporate decision-makers in bus operations.

**2. Trigger Conditions**

1. Invoice due date is approaching (e.g., 3 days before deadline).

2. Payment not received by due date (e.g., at midnight on due date or plus a grace period).

3. Invoice status changes to "overdue" in ERP or billing system.

4. Payment status updates (failure, bounce, or partial settlement).

5. Scheduled batch jobs for daily/weekly overdue scanning, automating checks and notifications.
