Prioritize WMS and API integration, SKU-level inventory accuracy, throughput capacity, returns and reverse-logistics processes, kitting/assembly capabilities, and demonstrated peak-season scalability. Also verify carrier connectivity, SLA terms, uptime guarantees, and regular operational reporting to align cost-to-serve with service expectations.

Choosing a 3PL near major highways and carrier hubs typically reduces transit days and allows access to more competitive freight lanes, lowering last-mile costs and improving delivery windows. Reduced transit and better carrier density translate into improved OTIF metrics and lower total landed cost when network design is matched to demand patterns.

Confirm bonded or customs-clearance support if importing, availability of temperature-controlled storage and validated refrigeration, pallet racking density, backup power, and HACCP or relevant compliance certifications. Review documented procedures for traceability, recall handling, and temperature monitoring to safeguard product integrity.

Request standardized cost models that break out storage, pick-pack, handling, and outbound freight; benchmark KPIs such as inventory accuracy, order cycle time, cost per order, and OTIF. Insist on monthly scorecards, root-cause analyses for exceptions, and contractual SLAs with financial remedies or service credits for clear performance governance.
