Prioritize on-time order cycle, picking accuracy, inventory accuracy, and return processing SLAs. Also evaluate WMS integration, carrier lead times, and reporting cadence to ensure transparency. Request real performance data for peak and off-peak periods and contractual KPI remedies for missed SLAs.

Closer proximity to primary highways reduces mileage-based transport costs and variability in transit time, improving predictability for last-mile delivery. Facilities near intermodal or consolidation hubs lower LTL rates and enable faster replenishment cycles, which is critical for omnichannel responsiveness.

Negotiate transparent storage and pick/pack tariffs, clear definitions for accessorial charges, minimums, and surge labor rates. Include performance-based KPIs, audit rights, and flexible capacity clauses to limit unexpected costs during seasonality or growth.
