Evaluate KPIs and systems integration: order lead time, pick accuracy, on-time dispatch, and returns processing. Verify WMS and carrier API integrations, peak capacity plans, and real-time inventory visibility. Also review physical audit reports, sample onboarding timelines, and documented SLAs to align expectations.

Prioritize multi-temperature zones, bonded options if you export, cross-dock capacity, and segregated picking areas for retail vs. bulk orders. Look for value-added services such as kitting, quality inspection, and labeling. Confirm forklift and racking density to optimize cubic utilization and throughput.

Compare landed cost components: pick-and-pack fees, storage per pallet and per cubic meter, inbound receiving charges, and outbound carrier passthroughs. Quantify transit-time savings to core markets and freight mode availability. Consider minimums, billing cycles, and scalability clauses to match seasonal demand.
