Prioritize a modern WMS with API/TMS integration, real-time inventory visibility, measurable SLAs (picking accuracy, order cycle time), scalable labor models, temperature control if required, and carrier-neutral billing. Look for reporting, exception workflows, and disaster recovery plans to support seasonal volume spikes and omnichannel flows.

Transit times and landed cost depend on proximity to primary routes, carrier density, and backhaul options. Better-connected facilities reduce empty miles and freight rates; seasonal road conditions and border handling can add variability. Factor scheduled pickup frequency and consolidation capabilities when estimating total landed cost.

Primary levers include lower real estate and labor rates, optimized inventory placement to reduce transit miles, consolidation to improve truck utilization, and reduced warehousing overhead through shared-services 3PL models. Also quantify inventory carrying costs and any added last-mile expenses for remote deliveries.

Assess carrier partnerships and delivery frequency, SLA for delivery windows, reverse-pickup capabilities, and refund/return reconciliation processes. Validate on-the-ground partner networks, parcel and LTL options, and performance metrics (on-time delivery, return cycle time) to ensure consistent omnichannel customer experience.
