Prioritize SLA clarity (order lead time, pick accuracy), WMS integration and reporting, dock and throughput capacity, inbound/outbound carrier connectivity, and scalability for peak seasons. Also assess labor availability, security, insurance terms and the partner’s experience with your product types to predict handling accuracy and cost-to-serve.

Road freight is the dominant mode; expect variability driven by border processes and regional road conditions. Model buffer stock for key SKUs, prioritize carriers with regular lanes, and evaluate consolidation opportunities. For time-sensitive orders, plan hybrid strategies that combine local buffering with occasional air or expedited services where available.

Key capabilities include secure racking and pallet handling, segregated returns and staging areas, temperature-controlled storage if needed, barcode-driven picking, and electronic inventory visibility. Verify customs clearance support, safety and security controls, and the 3PL’s ability to handle kitting, labeling and value-added services.

Include fixed and variable warehousing costs (rent, labor, utilities), inbound freight to the facility, last-mile distribution costs, inventory carrying costs from safety stock, and expected service-level penalties. Run scenario analyses on SKU segmentation, stock splits and demand variability to quantify total landed cost versus service improvements.
