Prioritize WMS/TMS integration, real‑time inventory visibility, pick/pack throughput, order accuracy, and SLA reporting. Confirm cold‑chain controls if needed, bonded storage availability for cross‑border sales, value‑added services (kitting, returns), and disaster recovery for continuity.

Closer proximity reduces drayage, shortens clearance cycles, and enables faster multi‑modal transfers—lowering transit time and landed cost. It also improves lead times for replenishment and supports next‑day or same‑day service patterns for domestic and regional deliveries.

Negotiate transparent fee structures (storage tiers, pick/pack, receiving), throughput discounts, minimums, fuel and handling surcharges, SLAs with credits for non‑performance, and IT integration fees. Include periodic rate reviews tied to volume or productivity benchmarks.

Confirm bonded warehouse licensing, customs brokerage capabilities, documentation accuracy, and whether facilities support deferred duty or re‑export processing. Verify compliance with product regulations, temperature monitoring for perishables, and record retention for audits.

Model transit times, service windows, and cost tradeoffs across nodes; decide split‑inventory vs centralized stock based on SKU velocity and delivery promises. Evaluate multi‑carrier reach, cross‑dock options, return flows, and the 3PL’s ability to scale slotting and labor during seasonal peaks.
