Prioritize measurable service levels: throughput capacity, pick/pack accuracy, lead times, and peak scalability. Verify warehousing infrastructure (racking, temperature control), IT integration (WMS + API connectivity), customs experience, bonded storage availability, and local carrier networks. Evaluate SLA terms, KPIs, and contingency plans for port or road congestion.

Closer warehouse locations reduce drayage and inland trucking distances, lowering demurrage risk and transport spend. Proximity improves reliability of ETAs and shortens last‑mile windows, which decreases inventory‑in‑transit days and enables more responsive replenishment strategies for both retail and B2B channels.

Look for integrated inventory visibility, real‑time order routing, multi‑channel pick/pack workflows, returns processing, and cross‑dock operations. The 3PL should support SKU segmentation, batching logic for eCommerce vs wholesale, and provide SLA‑backed cutoffs for same‑day or next‑day fulfillment.

Confirm the 3PL’s experience with local customs procedures, bonded warehouse licensing, and duty‑deferral options. Assess their documentation accuracy, customs brokerage partnerships, and processes for inspections and claims to avoid clearance delays and incremental costs.

Evaluate demonstrated peak season performance, access to overflow capacity or satellite sites, contractual flexibility for volume changes, and contingency logistics (alternative carriers, temporary storage). Review disaster recovery plans, insurance coverage, and financial stability to ensure continuity during growth or disruption.
