Evaluate inbound transit options (port/air), dock and staging capacity, WMS integration and EDI, SLA terms (pick-to-ship times, accuracy), and value-added services such as kitting, lot tracking, and returns handling. Also assess scalability, security, and local labor productivity.

Costs generally reflect lower real estate and labor rates but higher per-shipment ocean or air legs. Expect standard charges for storage, receiving, pick-and-pack, and fixed handling, plus variable freight and customs fees. Model total landed cost, not just warehouse rent.

Ensure the 3PL provides a modern WMS with real-time inventory visibility, carrier rate-shopping, returns management, and API/EDI connectivity to marketplaces and ERP. Confirm support for barcode scanning, batch picking, and exception workflows to reduce order cycle time.

Confirm customs brokerage capability, bonded/temporary storage options, duty management, and documentation accuracy to avoid clearance delays. Assess insurance, security certifications, and contingency plans for weather-related disruptions and cargo inspections.
