Evaluate carrier connectivity and transit lanes, proven WMS and API integration, SLA performance (OTD, accuracy), storage and handling capabilities for your SKU profile, seasonal capacity flexibility, labor productivity metrics, and transparent pricing (storage, pick/pack, IO/OT charges). Request references and KPI dashboards to validate operational consistency.

Transit times and lane options affect freight class, modal choice, and zone-based pricing. Shorter trunk-haul to key markets enables zone-skipping and lower parcel zones, reducing last-mile costs and delivery windows. Negotiate carrier rates, consolidation opportunities, and guaranteed transit SLAs to control landed cost and meet customer expectations.

Require a modern WMS with APIs/EDI for OMS and ERP connectivity, real-time inventory sync, lot/serial control, parcel/TMS interfaces, barcode/RFID support, and accessible reporting. Confirm cycle-count routines, exception handling workflows, and integration support for marketplace platforms and carrier label generation.

Compare usable cubic and pallet positions, racking density, dock capacity, shift patterns, and labor rates. Ask for productivity KPIs (pick/pack per hour, orders per labor hour), historical throughput during peaks, lead times for scaling footprint, and contingency plans for labor or equipment shortages.
