Prioritize carrier and port connectivity, real estate and labor costs, available SKUs per pallet metrics, slotting and throughput capacity, WMS/TMS integration, SLA flexibility, and cross-docking capability. Also assess transit times to your primary customer clusters and the provider’s experience with your product categories.

Track origin-to-door transit times by postal zone, freight and parcel spend per order, inventory days of supply, pick-and-pack labor hours per order, and on-time-in-full (OTIF) rates. Benchmark these KPIs before and after migration to quantify improvements in lead time and delivered cost.

Require WMS API access, EDI or API carrier connections, inventory accuracy targets, defined receiving and putaway windows, detailed chargeback rules, and contingency plans for seasonal surges. Specify data reporting cadence for inventory, orders, and exceptions to ensure operational transparency.

Lower regional labor and facility costs can reduce per-order fulfillment OPEX, enabling denser inventory posture and faster replenishment cycles. Assess workforce skill availability for value-added services and include labor escalation clauses in contracts to model multi-year cost exposure.

Confirm customs facilitation capabilities, bonded storage options, insurance limits, contingency transportation plans, and compliance with local import/export regulations. Validate the 3PL’s relationships with customs brokers and regional carriers to reduce border delays and unexpected fees.
