Prioritize verified inventory accuracy, SLA-backed picking and packing, returns processing, and customs/bonded services. Also assess IT integration (WMS/APIs), real-time tracking, handling equipment for container throughput, and scalability of labor during seasonal peaks.

Port proximity shortens dray and container handling times, while direct road and regional rail links reduce inland transit hours. This combination lowers landed cost and inventory-in-transit, improving delivery windows for B2B accounts and reducing buffer stock requirements.

Key SLAs include order accuracy, on-time dispatch, dock-to-delivery transit time, inventory reconciliation frequency, and claims resolution timelines. Tie pricing to volumetrics, dwell times, and chargebacks to keep cost-to-serve transparent.

Evaluate landed cost, duty and bonded handling fees, local labor rates, energy and security costs, and access charges at the port. Also consider workforce reliability, regulatory compliance for imports, and proximity to customers and suppliers that affect last-mile expenses.
