Prioritize proximity to major highways and rail links, available dock capacity, and direct carrier or pallet-network agreements. Verify WMS/API integration, cross-dock capabilities, customs brokerage access for cross‑border flows, and skilled temporary labor for peak periods to ensure predictable SLAs.

Costs generally include tiered storage (per pallet or per cubic meter), pick-and-pack by piece or SKU, inbound/outbound handling, and extras for kitting, labeling, or returns. Negotiate volume thresholds, demurrage terms, and billing cadences; review minimums and seasonal labor surcharges to model true landed cost.

Require real-time inventory visibility (WMS with API/EDI), defined pick-cutoff times, scalable workforce plans, returns processing, and automated carrier tendering. Clear KPIs for inventory accuracy, order cycle time, and on-time delivery are essential for managing peak demand effectively.

Evaluate average transit times to target markets, carrier lane coverage, consolidation options, and customs clearance speed. Confirm the 3PL’s experience with export documentation, bonded storage if needed, and optimized routing to nearby ports or inland hubs to reduce total transit and handling costs.
