## Smoke Test

- Run once and verify overdue list includes amount, aging, and suggested action.
- Confirm no messages are sent automatically.

## KPI

- Overdue invoice count
- Average days overdue
- Collection cycle time

## Security Notes

- Keep billing data in restricted channels.
- Start in draft-only mode with human approval required.
