Prioritize SLA performance, real-time inventory visibility (WMS integrations), dock door and racking capacity, order-picking efficiency, returns processing, and proximity to major carriers. Verify scalability for seasonal peaks and confirm access to regional trucking pools on I-5 to minimize transit variability.

Choosing a local 3PL reduces ground transit time to regional markets by shortening the first- or last-leg on the I-5 corridor, often lowering LTL and parcel rates through concentrated carrier activity. Savings depend on shipment density, carrier contracts, and whether the 3PL provides zone-skipping or pool distribution services.

Confirm WMS/APIs for order routing and inventory, kitting and light assembly, barcode-enabled receiving, managed returns, lot/serial tracking if required, and reporting for cost-per-order. These capabilities determine the 3PL’s ability to support omnichannel order profiles and complex B2B fulfillment SLAs.

Model landed cost impacts including rent per square foot, labor rates, local taxes and utilities, inbound/outbound transportation costs, handling fees per pick/pack, storage density (racking vs. bulk), and value-added service charges. Include scenario analysis for seasonal peaks and reverse-logistics volumes.

Request carrier manifests, transit-time maps, and references for similar clients; review zone-by-zone benchmarking for parcel and LTL; conduct a proof-of-concept with sample SKUs; and confirm real-time tracking and exception management capabilities to ensure last-mile SLAs are met.
