Prioritize WMS integration and real-time inventory visibility, pick-and-pack throughput, returns and reverse logistics processes, bonded storage if you need deferred duties, and clear SLA terms for order accuracy and lead times. Also assess kitting and light assembly capabilities for omnichannel offers.

Proximity to port feeders and primary highways reduces dray and inland transit, improving lead times and lowering landed cost. Evaluate available LTL, express courier density, and scheduled sea-feeder links—these determine consolidation opportunities and the ability to optimize routes for cost versus speed.

Compare storage (per pallet/cubic meter), pick-and-pack rates (per pick and per sku), inbound receiving and put-away fees, value-added service charges (kitting/returns), minimum monthly handling clauses, and accessorials such as long-term storage, labs, or special handling to calculate total cost-to-serve.

Track order accuracy, on-time shipment percentage, dock-to-stock days, pick rate per labor hour, inventory reconciliation variance, returns processing time, and SLA penalties. Monitor tech uptime and API transaction success to ensure integration reliability for omnichannel order flows.
