Every action is checked against this policy before it runs.
Questions, answered
Will it dispute or pay detention charges automatically?
No. WebRun tracks and logs charges only. Any dispute or payment action requires human approval and is never initiated automatically.
How does it know the free-time rules for each terminal?
It reads the shipment details and terminal notes in Labelmaster DGIS. You can also add terminal-specific free-time rules to the tracker sheet so WebRun can compare against your own records.
What if a shipment has already cleared the terminal?
It checks live shipment status in DGIS each morning, so cleared shipments are automatically removed from the at-risk list.
