• Location vs. customer zones and carrier hubs to minimize transit cost and lead time;
• Dock capacity, racking, temperature control, and scalability for peak volumes;
• WMS/TMS integrations, SLA terms, and labor models that match SKU velocity.

Carrier density and direct lane access influence transit time and freight rates. Choose 3PLs with established contracts or integrations with domestic carriers, LTL networks, and last‑mile partners to reduce handoffs, lower rates, and improve tracking reliability.

Benchmark on rent per sqm, labor hours per pick, dock turn times, inventory carrying cost, and value‑added service fees. Compare slotting efficiency, inbound/outbound ASN accuracy, and percentage of on‑time orders to quantify total landed fulfillment cost.

Yes. Look for dedicated temperature‑controlled storage, validated refrigeration, continuous temperature monitoring, documented cold‑chain SOPs, contingency power, and trained handling teams to ensure compliance and minimize spoilage.
