Prioritize facility layout (dock doors, racking, temperature control), WMS/OMS integration and real-time inventory visibility, SLA commitments for pick/pack/ship, labor models for peak scaling, and carrier connectivity for parcel and pallet networks. Include KPIs for order accuracy, on-time shipment, and cycle times in contracts.

Local 3PLs can consolidate inbound shipments, use bonded storage to delay duties, optimize pallet builds for carrier pricing, and leverage proximity to ports and road corridors to cut drayage and inland transit. Efficient customs handling and cross-docking also shorten delivery windows and lower per-unit landed costs.

Look for a modern WMS with API connectivity to marketplaces and ERP systems, real-time shipment tracking, automated pick-path optimization, returns management, and reporting dashboards. Confirm the 3PL supports multi-carrier rate shopping and EDI/API for freight and parcel carriers used by your business.

Negotiate clear SLAs for order lead times, accuracy, and shipment cutoffs; transparent fee schedules (storage, receiving, pick/pack, returns, special handling); audit rights for inventory and processes; penalties for SLA breaches; and exit provisions that protect inventory and data portability.
