Prioritize location relative to main transport corridors, demonstrated WMS integration and API capability, racked vs. bulk storage balance, value‑added services (kitting, returns), documented SLAs for order accuracy and lead times, and transparent tariff structures.

Carrier access influences linehaul pricing and lead times. Assess frequency of trucking lanes, proximity to rail spurs or intermodal terminals, typical dwell times, and availability of bonded or customs-cleared options—these factors directly affect per-shipment cost and on-time performance.

Look for modern WMS with real-time inventory, barcode-driven pick/pack, batch and wave picking, integrations for marketplace and carrier connectivity, temperature control where needed, returns processing, and capacity for seasonal scalability.

Model rent per pallet or sqm, labor rates and productivity assumptions, inbound/outbound handling fees, equipment and value‑added service charges, transportation lane costs to key customers, and inventory carrying costs to get a true landed cost comparison.
