Require clear, measurable SLAs covering order accuracy, on-time shipment rate, inventory accuracy, and lead times. Confirm reporting cadence, exception handling, chargeback terms, and remediation plans. Validate performance history with comparable customers and ask for sample scorecards and audit results.

Prioritize facilities with robust WMS integrations (API/EDI), real-time inventory visibility, scalable pick/pack capacity, reverse logistics capabilities, and temperature-controlled space if needed. Evaluate cross-dock capability, slotting strategies, and proximity to key carriers to reduce transit and last-mile costs.

Common cost components include receiving and inspection fees, storage per pallet or cubic foot, pick/pack and handling charges, packaging and kitting fees, outbound transportation and fuel surcharges, returns processing, and IT/WMS integration or transaction fees.
