Prioritize WMS and systems integration (order channels, EDI/APIs), carrier lane coverage and average transit times to your customer zones, clear SLAs for pick accuracy and order cycle time, capacity flexibility for peaks, and documented processes for returns and value‑added services.

Distance to major export gateways drives trucking time and cost; shorter domestic legs reduce handling and dwell. Consolidation opportunities and reliable carrier schedules lower per-unit costs. Also assess seasonal road constraints and customs handling to model realistic lead times and landed-cost impacts.

Compare occupied space rates (sqm), handling fees per pick/pack, storage density and binning efficiency, labor rates and overtime policies, minimum monthly charges, value‑added service fees (kitting, labeling), and fuel or carrier surcharges that affect total cost of fulfillment.

Request KPI reports (OTIF, pick accuracy), ask for live WMS demonstrations and API documentation, perform reference checks and site visits, review insurance and liability terms, validate sample pick/pack audits, and confirm documented processes for returns, quarantines, and disposition.
