Assess KPIs such as order accuracy, OTIF, pick-to-pack cycle time, and return processing speed. Verify WMS functionality, real-time inventory feeds, API/EDI connectivity, on-site automation, sample audits, and contingency plans for peak seasons to match SLA requirements.

Prioritize distance to major ports/airports, access to bonded zones/FTZs, container terminal capacity, quality of arterial roads, customs clearance throughput, and proximity to major carriers — these determine landed cost and transit reliability.

Look for a modern WMS with OMS/TMS integration, real-time API/EDI for carriers, barcode scanning, slotting and labor optimization, batch and lot tracking, and reporting dashboards that support PO-to-invoice reconciliation and SLA monitoring.

Common models include per-pallet or per-sqm storage, pick/pack fees, inbound handling, and throughput-based discounts. Negotiate minimums, volume tiers, performance-based rebates, termination clauses, and audit rights; align service levels with penalty/bonus structures.
