Late Arrival
Carrier Invoice Arrives

Manual PO Lookup
AP hunts for the PO and rated quote in a logistics reconciliation sheet.
3
3-Month Lag
Pay and Discover Later
Duplicate fuel surcharges and demurrage found months after payment.
Root Operational Bottleneck
Carrier freight invoices with accessorial charges are matched against purchase orders by eye in an AP queue spreadsheet, long after the shipment moved.
Control Hazard & Audit Exposure
Duplicate fuel surcharges and demurrage fees are paid and only surface months later; recovery depends on the carrier's goodwill rather than a control.
