Prioritize clear SLAs for pick/pack and lead times, WMS/TMS integration and reporting, equipment and racking that match SKU profiles, inbound/outbound carrier connectivity, and value-added service capabilities for eCommerce returns and kitting. Also verify scalability and contingency plans for peak seasons.

Location affects mileage-based transport cost, frequency of carrier runs, and last-mile delivery windows. A site closer to main trunk roads reduces linehaul expense and improves ETA reliability, while proximity to supplier clusters cuts inbound consolidation costs—together lowering total cost-to-serve.

Look for functional racking and material handling, secure storage, documented inventory controls, basic health & safety certifications, and a WMS with API support for order routing, inventory visibility, and returns processing. Demonstrated carrier integrations are essential for omnichannel speed.

Build a side-by-side cost model including storage (per pallet/cbm), handling (inbound/outbound), pick/pack labor, packaging materials, minimum monthly charges, transport uplift, and any pass-through fees. Factor in service metrics (accuracy, SLA) and projected volume shifts to assess true cost impact.
