Evaluate carrier density by checking scheduled departures, LTL and FTL coverage, and regular lanes to Austria/Slovenia. Verify 3PL carrier contracts, cross‑dock frequency, peak capacity commitments, and the ability to onboard new carriers quickly to maintain SLAs and minimize transit variability.

Require SLA metrics for order lead time, picking accuracy, dock turnaround, and inventory accuracy. Assess dock count, racking type, mezzanine and temperature control, WMS/ERP connectivity, returns processing speed, and the partner's ability to provide daily reporting and exception management.

Confirm customs brokerage capability, bonded or duty‑deferred storage options, and experience with transit documentation between Hungary and neighboring EU/Schengen states. Verify VAT handling, IOSS readiness for eCommerce, and the 3PL's processes for import/export audits and compliance.

Check the 3PL's ability to provide short‑term space increases, temporary labor scaling, overtime dock capacity, and modular racking. Review historical peak performance, contingency labor pools, contractual flexibility for temporary surge lanes, and IT capability to scale transaction volumes without SLA degradation.
