Request SLA metrics tied to pick accuracy, on-time outbound shipments, order cycle time, and inventory accuracy. Include chargeback thresholds for errors and defined processes for exceptions and returns. Require regular KPI reporting cadence and audit access to WMS logs to validate performance against agreed standards.

Map customer density against transport lanes and choose sites near major highways, intermodal yards, or ports. Model transit-time improvements versus rent and labor premiums, include distribution center fill rates, and simulate parcel zone-skipping to quantify landed-cost benefits before committing to a location.

Prioritize real-time WMS integration, ASN handling, kitting/assembly, returns processing, and temperature control where applicable. Also evaluate cross-dock capabilities, lot/batch traceability, and EDI/API connectivity to support marketplace and wholesale channels.

Confirm direct access to primary carriers, frequency of regional linehaul lanes, and proximity to intermodal terminals. Ask for sample transit-times by carrier, average weekly volumes, and contingency plans for peak season capacity constraints to ensure resilient multi-modal options.
