Prioritize WMS capabilities and integration (API/EDI), inventory accuracy, order cycle times, and returns handling. Also evaluate kitting/assembly, cold chain if required, peak season scalability, and reporting dashboards for inventory velocity and SLA compliance.

Feeder shipping frequency and local carrier networks directly affect transit times and consolidation options. Limited sailings increase consolidation lead times and inventory buffer needs, while robust feeder links reduce freight spend and last-mile transit. Evaluate carrier schedules, transshipment points, and contingency routing.

Key elements: storage (per pallet/cbm) and handling rates, labor surcharges, utilities, minimum monthly charges, inbound/outbound freight handling, detention/demurrage exposure, and inventory carrying costs. Also review contract terms for SLA penalties, volume discounts, and fuel or seasonal surcharges.

Define KPIs such as OTIF, order accuracy, pick-to-ship lead time, inventory accuracy, and returns turnaround. Require WMS access or regular reports, schedule quarterly operational reviews, and include clear SLA remedies. Regular cycle counts and mystery-shop audits help validate execution.
