Prioritize transit time to major demand centers, dock and staging capacity, carrier partnerships (LTL and truckload), inventory visibility (WMS/API readiness), and value-added services such as pick-and-pack, kitting, and returns processing. Also verify SLA terms, surge handling, and contingency plans for typhoon season.

Shorter regional transit reduces last-mile costs and delivery windows, while robust carrier coverage enables route optimization and LTL consolidation. Evaluate average miles-to-customer, carrier frequency, and transfer points to balance transportation spend against promised delivery times.

Require modern dock configuration, racked storage options, temperature control if needed, forklift and pallet handling capacity, and a WMS with real-time API or EDI for order flow. Confirm support for barcode scanning, returns workflows, and inventory reconciliation processes.

Model total landed cost including storage, handling, inbound/outbound transportation, and safety stock reduction from closer proximity to demand. Run scenario analyses on lead-time reduction, order fill rates, and peak-season handling costs to compare current vs proposed 3PL outcomes.
