Require metrics such as on-time dispatch, pick accuracy, inventory accuracy, and average order cycle time. Verify WMS functionality, EDI/API integrations, security and insurance, SLA penalties, and sample audit results. Conduct a site visit to confirm dock count, staging capacity, and staffing models for peak loads.

Prioritize highway and feeder road access for reliable TL/LTL movement, proximity to regional ports and air cargo services, carrier diversity (national and regional), dock door quantity, container handling, and cross-dock capabilities to minimize handoffs and reduce lead times.

Model total landed cost: include per-pallet/month storage, pick-and-pack fees, labor-hour rates, handling of inbound containers, local transport, and any customs or local taxes. Compare throughput-based pricing vs. fixed labor models and stress-test scenarios for peak season volumes to identify true cost per order.

Look for returns processing, inspection and refurbishment workflows, kitting/assembly, and cross-dock options. Insist on WMS with real-time inventory visibility, API or EDI connectivity for order management, and scalable labor or automation plans to ramp during promotions or holidays.
