Prioritize throughput metrics (orders per hour), dock door count relative to SKU volume, storage density, WMS/TMS integration and API capability, SLA terms for order accuracy and OTIF, and peak-season labor scalability. Check security, power, and material handling equipment to ensure consistent operations.

A regional 3PL shortens carrier miles to core markets, enables LTL consolidation and zone-skipping, supports cross-docking to reduce touches, and offers stronger parcel carrier density. Combined these reduce shipping zones, lower carrier costs, and improve delivery windows to customers.

Look for configurable pick lines, scalable labor pools, temporary surge staffing plans, automation for high-SKU picking, dedicated returns processing areas, clear reverse-logistics SLAs, and flexible footprint options to expand or contract during peak periods.

Negotiate clear SLAs (OTIF, accuracy, lead times), a transparent fee schedule (storage, pick, packing, accessorials), invoice audit rights, inventory ownership and insurance clauses, termination and transition plans, penalties for SLA breaches, and data access for performance monitoring.
