Require a WMS with real-time inventory, API integration for order and carrier systems, role-based access, configurable reports and audit trails. Confirm EDI/API capabilities for your OMS, SLA reporting cadence, sample data feeds and a documented onboarding timeline for integrations.

Prioritize dock door count and levelers, dedicated inbound/outbound areas, secure storage for high-value SKUs, flexible racking, clear pick-face zones, sufficient staging, and climate control if needed. Check throughput metrics and slotting strategies for peak season readiness.

Compare line-item cost models: receiving, storage (per pallet/CU), pick-and-pack, packing materials, returns handling, and monthly minimums. Define volume tiers, performance-based rate breaks, and clear SLAs for order accuracy, lead times and chargebacks. Insist on transparent invoicing examples.

Evaluate access to national parcel carriers, regional LTL networks, international freight forwarders and cross-dock partners. Key metrics: typical transit times to major metros, carrier density in your zones, on-time pickup rates and available export documentation/brokerage services.

Verify commercial liability and cargo insurance limits, facility security (CCTV, access control), certifications relevant to your product (temperature control, hazardous goods), written inventory audit rights, data protection for shared systems and clear liability language for loss, damage and shrink.
