Focus on WMS/API integration, real-time inventory visibility, pick-and-pack accuracy, returns processing, and scalability of labor and storage. Verify SLA terms for order cutoffs, shipping lane support, and exception handling. Inspect dock door counts, slotting practices, and seasonal capacity plans to ensure reliable omnichannel execution.

Key factors are proximity to major highways and sorting centers, density of parcel/LTL carriers, local fuel and labor rates, and warehouse rent per square foot. Zone reductions achieved by closer distribution points cut shipping tiers; carrier choice and lane frequency also materially change landed cost and delivery speed.

Require on-time fulfillment rate, order accuracy, pick-and-pack cycle time, inventory accuracy, dock-to-ship lead time, and claims frequency. Include reporting cadence, SLA remedies, and system uptime targets for integrations. Clear KPIs enable continuous improvement and transparent accountability.

Many regional 3PLs offer bonded or FTZ-capable facilities, accredited customs brokerage, and documentation management for cross-border flows. Confirm a provider’s experience with international compliance, import/export documentation, and partnerships with freight forwarders to ensure seamless B2B distribution and reduced border delays.
