Evaluate WMS functionality, inventory visibility, same-day/next-day picking capacity, returns processing and reverse-logistics workflows, and presence of temperature-controlled zones if you sell perishables. Also check SLA metrics, peak labor plans, and system integrations (API/EDI) with your storefront and carriers.

Close proximity reduces drayage and inland transit time for imports/exports, shortens door-to-door lead times for international lanes, and lowers risk of schedule conflicts. It also enables more frequent carrier sailings and air services, improving routing options and total landed-cost control.

Confirm bonded facility licensing, customs clearance performance, experience handling ATA carnets and temporary imports, accuracy in HS classification and duty deferral processes, plus documented compliance procedures for inspections and audits to avoid clearance delays or fines.

Review the provider's peak labor plans, use of temporary staffing pools, automation level for picking/packing, overtime policies, and historical throughput metrics during peak windows. Ask for seasonality case studies and measurable KPIs for throughput and accuracy.

Require real-time inventory feeds (API/EDI), order-status webhooks, scan-based reconciliation, standard KPI dashboards (OTIF, pick accuracy, lead time), and direct carrier manifesting or TMS integration to monitor transit times and freight spend.
