Prioritize proximity to port/major roads, multimodal access, transit times to your primary markets, and on‑site capabilities (cold storage, cross‑dock). Also verify WMS/API integration, SLAs for order cycle time, inventory visibility, security, and scalable labor options to match peak season demand.

Carrier density and lane frequency drive freight rates and transit reliability; limited lanes increase premium rates and buffer times. Efficient customs brokers and bonded warehousing reduce clearance delays and inventory dwell, lowering demurrage and improving customer promise accuracy.

Validate racking density, dock configuration, temperature zones, returns and refurbishment workflows, kitting/assembly space, IT integrations (WMS, EDI, API), reporting, and contingency plans for labor or equipment outages. Ask for throughput metrics and SLA remedies.

Model costs using SKU velocity, average on‑hand days, slotting needs, and accessorial fees (picking, packing, labeling). Include inbound freight, customs, minimums, seasonal surcharges, and expected shrink/returns. Run scenario forecasts for peak volumes to reveal true marginal costs.
