Prioritize transit-time impact, carrier neutrality, and the provider's network reach. Evaluate warehouse capabilities (bonded space, temperature control, cross-dock), labor scalability, WMS/API integrations, and historical throughput for seasonal peaks to align service levels with demand patterns.

Using a local 3PL generally reduces coastal and last-mile transit times and lowers landed costs through shorter road legs and reduced transshipment. Savings depend on route density, carrier agreements, and consolidation opportunities; assess lane-level pricing and average delivery times before committing.

Essential capabilities include real-time WMS with API/EDI, inventory visibility, pick-pack and returns workflows, temperature-controlled zones, secure bonded storage, and carrier-neutral consolidation. These drive inventory accuracy, faster order cycle times, and smoother omnichannel fulfilment.

Negotiate clear SLAs for order cycle time, dock-to-delivery metrics, chargeback rules, minimum volume commitments, ramp-up flexibility, rate review periods, liability and insurance terms, and audit rights. Include termination and data-access provisions to protect operational continuity.
