Prioritize carrier connectivity, demonstrated last‑mile reach, and flexible slotting for seasonal peaks. Evaluate WMS capabilities, inventory accuracy metrics, security and bonded storage options, turnaround times for pick‑pack, and transparent pricing that includes inbound/outbound handling and storage tiers.

Transport links determine consolidation frequency and LTL/FCL economics. Proximity to primary highways reduces trucking time to port and lowers fuel and demurrage exposure; longer feeder legs increase buffer inventory needs. Choose a 3PL with optimized carrier contracts and predictable routing to control transit variability.

Verify secure perimeter controls, CCTV and access logs, and audit procedures for inventory reconciliation. Confirm customs and bonded storage options if importing, review carrier liability limits, and ensure the 3PL provides cargo and public liability coverage aligned to your SKU value and regulatory needs.

Demand real‑time inventory visibility via WMS with API/EDI integrations to your OMS, automated order routing, and clear SLA targets for order cutoff, pick accuracy, and ship times. Assess reporting cadence for KPIs (OTD, accuracy, dwell) and the 3PL’s ability to scale throughput during promotions.
