Prioritize WMS with real-time inventory APIs, accurate receiving/putaway processes, configurable pick/pack SLAs, returns handling and reverse logistics, cross-dock capability and measurable KPIs (OTIF, inventory accuracy, pick errors). Evaluate staffing flexibility and peak-season capacity to ensure reliable omnichannel fulfillment under varying demand.

Close access to river terminals, improving road links to Sihanoukville port, and growing air cargo options reduce inland drayage and multimodal transfer time, lowering freight spend and transit variance. Shorter routes to Vietnam and Thailand corridors cut lead times for replenishment and improve reliability for time-sensitive B2B and eCommerce shipments.

Require a WMS with barcode scanning and API or EDI connectivity to inventory and order systems, configurable pick strategies (batch, zone, wave), returns management, quality control checkpoints, and real-time reporting. Ask for evidence of automated workflows, SLA dashboards and planned capacity for peak events to preserve delivery speed and accuracy.

Model fixed warehousing rent, variable handling and labor rates, inbound/outbound drayage, storage density and pallet fees, pick/pack pricing, returns processing and customs clearance charges. Include inventory carrying cost, service-level penalties, and last-mile delivery rates to calculate true cost-to-serve across SKU velocity and channel mix.
