Key metrics: average transit days to priority zones, on-time pick/pack accuracy, dock-to-delivery SLA, and inventory accuracy. Assess carrier presence (parcel, LTL, TL), multi-carrier tendering, and access to port/airport ramps. Request route-specific transit tests and SLA credits tied to measurable KPIs.

Prioritize real-time WMS with API/EDI connectivity, configurable pick/pack workflows, lot and expiry tracking, batch/slotting support, and reverse logistics processing. Confirm support for barcode scanning, cycle counting, integration with marketplaces, and ability to scale racking or automation as SKU velocity grows.

Labor productivity and local wage levels drive picking and handling rates; incentives or tax zones can lower occupancy costs. Property availability influences lease structure and expandability. Evaluate blended cost-per-order models, seasonal labor ramps, and contract terms for short-term capacity spikes to avoid excessive variable fees.

Design a network that separates fast-movers in forward nodes from bulk inventory in regional hubs, enforce single-inventory visibility across channels, implement routing rules for channel-priority shipments, and define reverse flows for returns. Establish clear KPIs, regular performance reviews, and contingency plans for peak periods.
