Prioritize carrier reach (parcel/LTL/export), SLA performance (pick/pack lead times), systems integration (WMS/EDI/APIs), slotting and racking capacity, and value-added services such as kitting and returns processing. Also evaluate dock door throughput, yard capacity, and contingency plans for peak season scalability.

Proximity to port terminals and major highways reduces drayage and highway transit, lowering lead times and freight spend. Competitive land costs can reduce warehousing rent per pallet, improving break-even for inventory velocity. Consider inland carrier interchanges and consolidation windows when modeling total landed cost.

Negotiate transparent piece rates for inbound, storage, and outbound; minimums and volume tiers; detention and demurrage exposure; SLA credits; and IT connectivity fees. Include clear rebill rules for returns, value-added services, and peak-season surcharges to avoid hidden cost variability.

Ensure available temperature-controlled chambers with monitored alarm systems, bonded and customs-cleared spaces for export prep, appropriate racking and segregation for inventory integrity, and reliable power redundancy. Confirm the 3PL’s export documentation and carrier booking experience to streamline cross-border moves.
