Evaluate location relative to customer clusters and carriers, transit times, service-level agreements, inventory accuracy, WMS/OMS integration, returns handling, value-added service capability, scalability for peaks, and transparent cost-to-serve metrics to compare total landed fulfillment cost.

Proximity to major highways and a dense carrier network lowers mileage and enables more efficient LTL and parcel routing, reducing both transit times and freight expense. Centralized sites also allow fewer fulfillment nodes while maintaining delivery SLAs for multiple channels.

Require WMS and OMS connectivity (API/EDI), real-time inventory visibility, support for pick-and-pack and omnichannel order routing, automation for high-volume SKUs, climate control if needed, and documented KPIs for accuracy, throughput, and chargebacks.

Run standardized cost models that include receiving, storage, pick/pack, shipping, returns, and accessorials; request historical SLA and accuracy reports; define volume tiers and minimums; and negotiate transparent reconciliation terms, liability limits, and exit clauses to reduce commercial risk.
