Evaluate WMS capability and API connectivity, SLA metrics (OTIF, inventory accuracy), customs and bonded capacity, pick-pack throughput, available value-added services (kitting, returns), labor scalability, and documented carrier networks. Ask for KPIs, audit rights, and integration roadmaps to ensure predictable cross-border fulfillment.

Proximity to port and primary road arteries reduces inland drayage and transit times, lowering landed costs and improving delivery predictability. Limited carrier frequency or poor road conditions can increase buffer stock and transit variability, so evaluate carrier schedules, consolidation options, and last-mile partners when selecting a warehouse.

Require real-time API or EDI order and inventory sync, ASN support, barcode scanning and lot/serial tracking, returns management, and customizable dashboard reporting for OTIF, cycle counts, and order exceptions. Confirm test environments, SLAs for outages, and data security controls before go-live.

Negotiate clear SLAs (OTIF, pick accuracy), volume-tiered pricing, minimum term and exit provisions, liability and insurance limits, chargeback policies for service failures, ramp-up windows, and periodic performance reviews. Include provisions for seasonal surges, audit access, and change-management for tech integrations.
