Require measurable KPIs: order accuracy (%), on-time departure to carrier, dock-to-stock cycle time, lead-time variance for replenishment, and peak throughput capacity. Include SLA terms for inventory reconciliation cadence, chargeback triggers, and tech/API uptime to ensure carrier and marketplace integrations remain stable.

Bonded warehousing in Sfax defers duties until import finalization, enabling consolidation and improved cash flow. Efficient customs brokerage and export facilitation reduce port dwell time and consolidation delays, lowering per-unit landed cost and shortening door-to-door transit when combined with synchronized carrier schedules.

Prioritize proximity to the port, available dock capacity and cross-dock lanes, racking and cold-chain infrastructure, scalable labor pools, contingency power and security, and the 3PL's ability to scale temporary labor and storage during peaks. Verify WMS/OMS integrations and lead-time to expand footprint if needed.
