Prioritize order accuracy, pick-and-pack productivity, SLA adherence, and inventory turn. Evaluate warehouse layout, racking and slotting, temperature control, cross-dock capacity, WMS integration, and dock/yard configuration. Confirm carrier access, lead-time reductions, and ability to scale for peak seasons to ensure cost-effective service levels.

Proximity to major roads and rail minimizes linehaul time and variable transport spend. Strong carrier networks increase tender acceptance and routing options, lowering detention and accessorials. Assess transit-time maps to core customers and volume-based carrier rates to model landed cost trade-offs for different fulfillment nodes.

Key cost drivers include space rental (per pallet or per sq ft), inbound/outbound handling fees, pick/pack labor rates, slotting and labor optimization, WMS and integration fees, and value-added service charges. Factor in transport cost changes from carrier selection and inventory holding costs tied to lead times and safety stock.

Require API or EDI connectivity to your eCommerce and ERP systems, defined SLA benchmarks, an onboarding project plan with milestones, test order flows, and exception management procedures. Verify training programs for handling SKUs, returns processes, kitting capabilities, and real-time inventory visibility to minimize go-live disruptions.
