Prioritize facility layout for mixed SKU flows, racking and mezzanine capacity, dock configuration, and segregation for temperature-controlled inventory. Evaluate WMS capability, real-time inventory APIs, carrier integrations, SLA reporting, and reverse logistics processes to ensure omnichannel responsiveness.

Choosing a 3PL close to manufacturing reduces inbound drayage, consolidates cross-dock opportunities, and shortens cycle times. Lower regional warehousing rates and improved carrier routing decrease transportation premiums and minimize safety stock needs through more frequent replenishment.

Require clear KPIs: on-time outbound rate, pick accuracy, inventory reconciliation frequency, dock-to-stock cycle, and order lead time. Include penalties or performance credits in the pilot SLA and mandate regular operational reviews with root-cause analysis for exceptions.

Assess proximity to national highways, regional distribution centers, and feeder rail/port services that affect carrier mix and transit lanes. These factors determine parcel vs. LTL routing, consolidation windows for bulk moves, and potential for dedicated carrier contracts to lower per-unit shipping costs.
