Prioritize proximity to main highways and logistics hubs, carrier network coverage, WMS and API integration, temperature-controlled storage if needed, returns and kitting capabilities, customs and compliance experience, transparent SLAs and scalability options that match expected volume growth.

Land and labor rates in Kilis are generally lower than Istanbul or Izmir, which reduces per‑sqm and handling costs. Include last‑mile and trunk transport, carrier frequency, inventory holding, and value‑added labor in total landed cost to ensure savings aren’t offset by longer transit legs or limited carrier options.

Confirm the 3PL’s customs brokerage capabilities, bonded warehouse options and experience with import/export documentation. Verify compliance processes, required permits, sanctioned‑party screening, and how the provider handles inspections and transit documentation for cross‑border shipments.

Typical onboarding ranges from 6–12 weeks for standard WMS integration, basic layout and process alignment. Complex setups—including custom racking, multi-temperature installs, bespoke IT integrations or bonded status—can extend timelines to 3–6 months. Allow time for carrier testing and SLA validation.
