Prioritize SLA adherence, dock and staging capacity, WMS/OMS integration, real-time inventory visibility, returns processing, and multi-shift labor availability. Assess cold-chain, kitting, and cross-dock throughput to match SKU velocity and peak season demand. Require clear KPIs and audit rights to monitor service levels and cost-to-serve.

Carrier density and port connectivity determine frequency, consolidation opportunities, and drayage costs. Strong carrier networks reduce transit times and enable competitive rates; limited service drives reliance on regional feeders and increases cost. Model lane frequency, consolidation windows, and seasonal capacity when estimating landed cost and promised delivery times.

Require a modern WMS with API/EDI connectivity, real-time inventory, barcode/RFID support, configurable pick strategies, and batch/expiry controls. Evaluate automation readiness, kitting and returns workflows, scalability for peak volume, and reporting capabilities that support continuous improvement and capacity planning.

Negotiate transparent storage and handling rates, minimums, receiving and cut-off windows, demurrage/detention responsibilities, SLA penalties, and pass-through charges. Secure volume-tier pricing, clear billing for value-added services, audit rights, and defined performance credits to avoid hidden fees and manage total cost-to-serve.
