Prioritize on-time shipment percentage, average order lead time, dock door count and throughput, inventory accuracy, and peak capacity. Verify carrier lane coverage to key zip codes, reverse-logistics procedures, SLA penalties, and whether the facility supports EDI/API integrations for real‑time inventory and order tracking.

Compare landed cost by modeling transport lanes, transit time reductions, and occupancy rents. Factor lower lease rates, fuel and last‑mile transit reductions to Switzerland, differences in labor rates, and potential tariff or customs handling savings. Run a 12‑ to 36‑month total cost of ownership scenario including ramp costs and service‑level impacts.

Require zone‑skipping carrier options, parcel consolidation, split‑cart pick and multi‑channel order orchestration, returns processing, and scalable pick/pack labor. Confirm same‑day cutoffs, real‑time inventory visibility, and the ability to run promotions or seasonal surges without compromising SLA consistency.
