Prioritize WMS/API compatibility, pick‑and‑pack accuracy, order cycle times, on‑time shipping SLAs, inventory visibility, peak season scalability, and reverse logistics. Also verify carrier integrations and proof‑of‑delivery processes to ensure your fulfillment KPIs are achievable.

Closer proximity reduces inland transit time, lowers drayage and handling costs, and expands carrier choices for both ocean and air. This can shorten lead times for replenishment and improve reliability for time‑sensitive SKUs, while enabling more competitive landed costs.

Key capabilities include multi‑temperature storage, barcode scanning and lot tracking, kitting/assembly, returns processing, same/next‑day fulfillment options, and robust WMS and EDI/API integrations to support omnichannel order flows and inventory accuracy.

Evaluate import duties deferral via FTZs, bonded warehousing fees, inventory carrying costs, local labor rates, and drayage. Factor in cycle times for customs clearance, duty optimization strategies, and how storage in FTZs impacts working capital and order fulfillment lead times.
