Require measurable KPIs such as order accuracy, on‑time shipment rate, inventory accuracy, dock‑to‑stock cycle time, and chargeback thresholds. Contractually define SLA remedies, invoice audit rights, audit cadence, data exchange formats (EDI/API), and capacity commitments for peak seasons to maintain transparency and avoid hidden costs.

Compare transit time versus drayage and local delivery costs: port‑adjacent sites reduce ocean-to-warehouse moves but may increase last‑mile spend to inland customers. Model demand zones, inventory carrying costs, and cross‑dock frequency to decide whether coastal consolidation or distributed inland nodes minimizes total supply‑chain cost.

Prioritize WMS/WCS integration, omnichannel pick/pack workflows, returns management, kitting and light assembly, and access to reliable last‑mile carriers. Also assess dock configuration, slotting flexibility, and bonded/ customs processing capability to reduce lead times and support varied fulfillment channels.

Major cost drivers include storage density, handling fees per pick, inbound receiving charges, and seasonal labor premiums. Negotiate blended occupancy/throughput pricing, tiered volume discounts, caps on ancillary fees, shared labor pools, and incentives tied to performance to align cost with throughput and reduce surprise charges.
