Evaluate transit times to core markets, proximity to interstates/rail, warehouse capacity and ceiling height, automation and cold-chain capabilities, labor availability, WMS/API integration, SLA guarantees, returns processing, and local incentives. Prioritize partners that can scale throughput while maintaining visibility into inventory and order-level KPIs.

Close access to major highways and regional parcel hubs reduces last-mile transit and enables more favorable LTL consolidation windows. Carrier lane density improves pickup frequency and dynamic routing options, lowering transit time variability and often reducing parcel zone-related surcharges for regional shipments.

Require a modern WMS with real-time inventory, API/EDI connectivity to marketplaces and ERPs, configurable pick-and-pack workflows, batch and wave planning, returns management, and reporting on throughput, pick accuracy and SLA adherence. Automation and scalable labor models help meet peak demand consistently.

Include inbound freight to the DC, storage and handling fees, outbound parcel and LTL costs, inventory carrying costs, and service-level penalties. Model scenario-based transit times to customers and returns flows; a lower facility cost may be offset by higher last-mile freight if transit zones increase parcel miles.
