Prioritize providers with WMS and API/EDI integrations, pick-and-pack with SKU-level accuracy, kitting and returns processing, temperature-controlled storage if needed, SLA-based picking and dispatch, and real-time inventory visibility to reduce stockouts and improve order cycle times.

Port proximity shortens ocean lift and truck drayage; regular feeder services and airport links enable faster inbound replenishment. Limited road capacity or seasonal constraints can increase inland transit variability, so evaluate carrier schedules, consolidation options, and contingency routing to control cost-to-serve.

Confirm a 3PL’s customs brokerage credentials, bonded warehousing availability, quarantine and inspection handling, documentation accuracy for duties/GST, and experience with permits or product-specific regulations. These factors reduce clearance time and unexpected compliance costs.

Analyze demand density, transit-time maps, inventory segmentation (e.g., fast movers vs buffer stock), and total landed-cost trade-offs. Model multi-node scenarios for service improvement versus inventory carrying costs, and ensure the selected 3PL can scale for peak seasons and integration requirements.
