Prioritize WMS integration, real-time inventory visibility, pick-and-pack throughput, returns processing, kitting and light assembly, secure bonded areas if needed, and SLA-backed performance metrics. Confirm EDI/API connectivity to marketplaces and carriers plus local customs-clearance expertise to minimize dwell time.

Port feeder services, regional rail corridors, and trunk-road links determine transit windows and consolidation options. Good carrier access reduces transit variability, enables lane optimization (ocean-to-rail or direct truck), and improves predictability for B2B schedules and retailer cutoffs.

Compare space rental and storage tiers, per-pick and handling fees, inbound receiving charges, pallet and SKU storage terms, labor rates, IT/integration fees, customs and duties handling, minimums, and seasonal surcharges to model landed and per-order costs accurately.

Define measurable KPIs (OTD, inventory accuracy, pick accuracy), include service credits for missed SLAs, require visibility and reporting cadence, validate disaster recovery and contingency plans, and include clear expansion clauses and review milestones for capacity planning.
