Drayage trucking is a precision game. Drivers operating at container terminals and intermodal ramps work within narrow appointment windows, face congestion that can cost hours of unproductive time, and carry containers subject to daily per-diem charges if not returned before free time expires. The dispatch, scheduling, and documentation work behind every move is substantial—and in 2026, virtual assistants are increasingly managing that administrative layer.
The Scope of U.S. Drayage Operations
The American Trucking Associations (ATA) reports that trucking carries approximately 72.5% of all freight tonnage in the United States, with drayage—the short-haul truck movement connecting ports, rail ramps, warehouses, and importers—representing a critical first and last link in container supply chains. The Journal of Commerce and PIERS data track U.S. container port throughput in the tens of millions of TEUs annually, each requiring drayage moves at origin and often at destination.
Port congestion events, documented extensively during the 2020–2022 supply chain crisis and recurring in 2024–2025 at key West Coast and East Coast ports, have highlighted how appointment system management and per-diem exposure have become major financial risks for drayage carriers. The Pacific Merchant Shipping Association (PMSA) has reported that drayage carriers and their importer customers collectively incur hundreds of millions of dollars in annual demurrage and detention charges—much of which is driven by scheduling failures that better administrative coordination could reduce.
Dispatch Coordination and Driver Communication
Drayage dispatch involves matching driver availability to available loads, confirming pickup and delivery appointments, communicating stop sequences and special handling instructions, and logging actual move times against planned schedules. VAs support dispatchers by managing load tendering from IMC and freight broker partners, updating dispatch boards in TMS platforms, and confirming appointment status with terminal operators.
For drayage companies running 30–100 power units, the administrative volume of load management and driver communication occupies multiple dispatcher positions. VAs handling the routine communication and data entry components of dispatch support allow dispatcher staff to focus on real-time problem-solving—congestion rerouting, driver breakdown response, appointment reschedules.
Port Terminal and Rail Ramp Scheduling
Port terminal appointment management is one of the most operationally sensitive functions in drayage. Terminals including those operated by APM, SSA Marine, and TraPac use online appointment systems that require advance booking, confirmation management, and rapid rescheduling when loads are unavailable or drivers have conflicts. VAs manage this appointment workflow: monitoring container availability in terminal systems, booking appointments at the earliest available window, and coordinating reschedules when necessary.
Rail ramp appointment management for intermodal first-mile and last-mile moves follows a similar pattern, with the added complexity of railroad free-time rules and gate hour constraints at the ramp.
Per-Diem and Demurrage Exposure Management
Per-diem charges—daily fees assessed by ocean carriers when containers are not returned within free time—represent a direct cost to drayage operators or their shipper clients. Managing per-diem exposure requires tracking container free-time expiration dates, identifying containers at risk before charges accumulate, and coordinating priority scheduling for at-risk returns.
VAs maintain per-diem tracking logs, send internal alerts when containers approach free-time expiration, and prepare dispute documentation when charges are assessed on containers that were delayed by terminal or carrier fault. The PMSA has published research indicating that a meaningful proportion of assessed demurrage charges are disputable given terminal-side delays—but only when documentation is prepared promptly and accurately.
Billing and Accessorial Administration
Drayage billing includes base rate, fuel surcharge, chassis fees, congestion surcharges, hazmat fees, and detention—each of which must be documented and applied to the correct shipment. VAs assist with invoice preparation, accessorial charge documentation, and collections follow-up on outstanding importer or broker invoices. For operators with high transaction volume, billing accuracy and collections cycle time are direct profitability levers.
The Bureau of Labor Statistics places transportation dispatchers at median annual wages above $48,000, and the administrative intensity of port-area drayage—compared to long-haul trucking—often requires more coordinator hours per truck than in other trucking segments.
For drayage trucking companies looking to improve dispatch support, reduce per-diem exposure through better scheduling, and accelerate billing throughput, Stealth Agents provides virtual assistants with port operations and trucking administration experience.
