Focus on measurable operational KPIs: on-time dispatch rate, order accuracy, average pick-and-pack time, dock door utilization and throughput per shift. Evaluate infrastructure metrics such as racked storage density, number of dock doors, cold-chain capability (if needed), WMS/API integration readiness and local labor availability to forecast scalability and cost per order.

Choosing a 3PL in this location affects lead times and documentation flows. Providers with customs experience and bonded storage can reduce clearance delays. Assess their freight partner network for sealed transit routes, familiarity with export/import paperwork, and established relationships with clearing agents to manage cross-border variability and reduce dwell time.

Key cost drivers include occupancy (rent per pallet/rack), labor rates and productivity, pick-and-pack fees, inbound/outbound transportation costs, inventory carrying charges, technology fees (WMS/API), and value-added services. Compare pricing models: per-pallet vs. per-order, minimum throughput guarantees, and surge/seasonal rate structures.

Request historical throughput data, references for seasonal peaks, SLA performance reports, and a site tour or video of operations. Verify WMS functionality and integration tests, contingency plans for labor or equipment shortages, capacity commitments (dock doors, storage bay counts), and contractual remedies tied to performance KPIs.
