Prioritize WMS and API/EDI integration, order-to-ship lead times, pick/pack accuracy, real-time inventory visibility, returns processing, and documented SLAs for OTD and accuracy. Also assess seasonal surge staffing, cross-dock capability, and the provider's carrier network for Sardinia-mainland lanes.

Key cost drivers include storage (per pallet/sqm), pick-and-pack fees, inbound and outbound handling, palletizing, minimum monthly charges, fuel and ferry surcharges, seasonal premiums, and any customs or temperature-controlled handling costs associated with your SKU profile.

Ferry frequency and scheduling determine consolidation windows and transit predictability to the mainland. Limited sailings increase inventory-holding needs or require earlier cutoffs; diversified carrier options and consolidation partners reduce risk and can lower last-mile costs when combined with regional distribution nodes.

Require documented SLAs for on-time delivery and accuracy, ASN/EDI support, batch and lot traceability, temperature control where relevant, certified handling for regulated goods, customs clearance experience for intermodal shipments, and clear KPIs and reporting to support supplier scorecards.
