Prioritize location relative to key markets and carriers, WMS and API integration, dock and cross‑dock capacity, SKU storage requirements (ambient/cold), and demonstrated accuracy/SLAs. Consider service depth (kitting, returns, labeling) and scalability to match seasonal volumes. Track KPIs like OTIF, inventory accuracy, and pick speed.

Suining generally offers lower land and labor costs than coastal ports, which can lower storage and handling rates. Model total landed cost by combining: transportation (inbound/outbound), inventory carrying, order processing, duties/tariffs, and reverse logistics. Include service-level premiums for expedited or cold-chain handling.

Require a modern WMS with real‑time inventory, robust API/EDI for marketplace and ERP integration, batch/lot and expiry tracking for regulated SKUs, barcode/scan validation, exception workflows, and reporting dashboards. Ensure the provider supports multiple fulfillment flows (store replenishment, direct-to-consumer, B2B pallets).

Domestic lead times vary by region but benefit from strong highway and regional rail connections; express networks cover major inland cities within 1–3 days. For exports, rail and road links to Chengdu/port gateways are common. 3PLs optimize routing via zone skipping, consolidation, cross‑dock schedules, and dynamic carrier selection to reduce cost and transit time.
