Prioritize carrier connectivity, real estate scalability, and technology stack compatibility. Look for WMS with API/EDI, proven returns processing, SLAs for pick-and-pack, and options for bonded or temperature-controlled storage. Confirm labor availability and contingency plans for peak seasons.

Transit times from Babek drive parcel and LTL zone pricing and influence safety stock. Evaluate access to intermodal nodes, hub airports, and major highways. Use density-based placement to reduce zone-skipping costs and choose 3PLs with strong carrier relationships to negotiate better rates.

Services that reduce handling and inventory carrying are key: automated pick/pack, batch picking, multi-client inventory segregation, and value-added services like kitting. Additionally, integrated inventory visibility via WMS reduces stockouts and lowers expedited freight spend.

Confirm the 3PL's experience with customs brokerage, bonded warehousing, and required certifications. Verify their documentation workflows, duty-deferral capabilities, and compliance processes for HS classification, as well as insurance and liability terms for cross-border cargo.
