Prioritize WMS integration, pick-and-pack throughput, racking and storage density, temperature control if needed, inbound/outbound dock capacity, and proven carrier relationships. Also evaluate reporting, inventory accuracy, and scalability to handle peaks and SKU growth.

Proximity to primary arterial roads and regional hubs reduces travel distance and fuel costs, improving delivery windows. Locations closer to carrier terminals enable faster handoffs and lower last-mile rates; consider cross-dock capability and distribution radius when modeling cost-to-serve.

Negotiate transparent rate cards for storage, pick/pack, and inbound handling; billing increments; minimums and volume discounts; SLA metrics with remedies; seasonal flexibility; and clear pass-throughs for carrier charges and value‑added services.

Track inventory accuracy, order cycle time, on-time delivery, dock-to-stock throughput, pick productivity, and cost-per-order. Use these KPIs to compare providers and drive continuous improvement in fulfillment operations.
