Evaluate transit times to key customer zones, warehouse layout and slotting for SKU velocity, WMS capability and API integration, handling of returns and kitting, labor availability and seasonal scalability, and clear SLA and chargeback terms to align service with cost.

Location drives last‑mile distance and fuel costs, affects eligibility for regional carriers and service windows, and influences transit reliability. Proximity to major highways and distribution nodes reduces delivery time and allows better carrier negotiation for volume and rates.

Require a modern WMS with real‑time visibility, scalable racking and staging, cross‑dock and returns processing flows, temperature‑controlled areas if needed, integration APIs for OMS/marketplaces, and documented capacity plans for peak volumes.

Typical fees include per‑pallet storage, pick‑and‑pack per order/item, receiving, and handling charges. Negotiate volume tiers, minimums, performance credits, rate review windows, and bundled service discounts; request transparent audit rights and clear surcharges to reduce unexpected variability.
