Focus on throughput (picks per hour), dock and bay capacity, storage density (pallet/rack mix), available value-added services (kitting, labeling), WMS integration capabilities, SLA guarantees, inventory accuracy, and proven carrier lane performance to ensure the 3PL meets both peak eCommerce demand and steady B2B shipments.

Placement near primary highways and distribution corridors reduces line-haul mileage and enables same- or next-day delivery to nearby population centers. Proximity to major carrier hubs lowers drayage and handoff times, while strategically located facilities enable better inventory segmentation and lower overall last-mile spend.

Require a robust WMS with real-time inventory visibility, API/EDI integrations for order flow, automated shipment notifications, electronic proof of delivery, returns management workflows, and access to standardized performance dashboards for pick accuracy, cycle times, and carrier metrics.

Compare storage cost per pallet/bin, pick-and-pack rates, inbound receiving fees, cross-dock and handling charges, minimum monthly activity fees, detention and demurrage exposure, and any uplifts for peak season. Ensure SLAs, liability terms, and billing transparency are clearly documented.
