Prioritize WMS functionality and API/EDI connectivity, inventory segmentation (multi-SKU handling), clear SLAs for pick/pack and returns, capacity flexibility for peak seasons, and proven experience with omnichannel order routing. Validate on-site processes, reporting cadence, and ability to integrate with your order management systems.

Xiangtan often delivers lower land and labor costs versus coastal ports, lowering basic storage and handling rates. Cost-to-serve is influenced by transport legs to ports or end markets, inventory days, package density, frequency of orders, and required value-added services like kitting or cold storage.

Key factors include proximity to major highways and rail terminals, inland river transfer options, regional carrier density for last-mile, and nearby air cargo capacity. Consolidation points and carrier schedules also determine lead times; choose a 3PL with established carrier contracts and visibility tools.

Negotiate order accuracy, OTIF, pick-and-pack throughput, inventory accuracy, return-processing windows, and maximum dwell times. Include clear penalties/incentives, capacity ramp-up clauses, audit rights, and requirements for system integrations and data reporting to ensure operational transparency.
