Prioritize WMS/API compatibility for inventory visibility, SLA definitions for order cycle and OTIF, scalable slotting and automation for peak volumes, turnkey returns and reverse-logistics, and carrier connectivity for multi-modal routing. Also validate reporting cadence and dispute resolution processes to protect service levels and margins.

Proximity to Swiss and Austrian borders and nearby air/road gateways reduces transit miles and enables more consolidation options. Strong carrier density supports competitive rates and routing flexibility, which lowers landed cost and transit variability when integrated into a multi-node fulfillment strategy.

Look for real-time WMS with API integration, automated pick-pack systems, temperature-controlled and bonded areas, integrated carrier shipping platforms, and capacity for kitting and value-added services. These features increase throughput, accuracy, and the ability to handle SKU proliferation without rising unit costs.

Negotiate transparent charge structures (storage, picks, receiving, returns), volume tiers with clear thresholds, SLA-backed penalties for OTIF or accuracy failures, regular KPI reporting, and predefined change-order terms. Ensure audit rights and clear escalation paths to manage unexpected cost drivers.
