Prioritize transport connectivity (motorways and rail access), proximity to key customer clusters, warehouse throughput capacity, labor availability and costs, and technology compatibility (WMS/API). Also evaluate inbound consolidation options, customs handling for cross-border flows, and demonstrated SLA adherence for pick/pack and shipping windows.

Calculate landed cost by combining storage, pick-and-pack, packaging, inbound freight, and outbound shipping rates plus payment for returns handling. Compare transit time distributions to your customer base, on-time shipping metrics, and dimensional pricing impacts. Request sample T&E scenarios that reflect peak volumes and promotions for accurate benchmarking.

Look for a modern WMS with API connectivity to your ERP and storefronts, real-time inventory visibility, order routing rules for channel-specific SLAs, EDI or API integrations with major carriers, and support for barcode/RFID workflows. Confirm reporting cadence and exception management for returns and split shipments.

Expect variable labor scaling, temporary storage expansion, flexible slotting strategies for SKU velocity changes, and clear short-term lease or throughput-based pricing. Verify capabilities for value-added services like kitting, light assembly, serialization, and temperature control where required, plus contingency plans for supply chain disruptions.
