Evaluate SLA metrics (OTD, order accuracy), throughput and peak capacity, WMS/APIs for inventory visibility, cross-dock and bonded capabilities, labor productivity, and carrier connectivity. Match the 3PL’s zone-skipping and reverse-logistics processes to your SKU velocity and customer promise.

Closer proximity to port and intermodal links reduces drayage, shortens lead times, and lowers variability in inbound schedules. That translates to lower buffer inventory, reduced safety stock, and improved on-shelf availability—key drivers of lowered landed cost for regional lanes.

Negotiate clear KPIs (accuracy, lead times), volumetric pricing bands, seasonal capacity commitments, liability and insurance terms, termination and transition SLAs, and integration milestones for EDI/API. Define chargebacks and remedies for repeated SLA breaches.

Prioritize a WMS with real-time inventory visibility, API/EDI connectivity to your OMS and carriers, reporting on cost-to-serve, and modules for value-added services. Ensure the 3PL supports scalable automation and provides dashboards for actionable distribution metrics.
