Shortlist partners based on location relative to key routes, throughput capacity, order pick accuracy, WMS integration and API readiness, SLA history, value-added services (kitting, returns), and pricing transparency. Validate references for peak-season performance and tech-supported inventory visibility.

Compare actual transit-time reports, carrier contracts, number of carrier lanes served, daily dispatch schedules, last-mile partnerships, and historical on-time delivery metrics. Include carrier mix, service variability during peaks, and contingency routing in the evaluation.

Assess fixed and variable elements: receiving, storage (by volume/weight), pick & pack, packing materials, outbound freight, returns handling, monthly minimums, onboarding/IT fees, and value-added charges. Model scenarios for seasonality, SKU mix, and average order value to compare true cost-to-serve.

Yes—when the provider operates segregated workflows, dedicated dock doors, configurable pick zones, and a WMS that supports mixed pick profiles. Confirm capacity buffers, cross-dock options, slotting strategies and SLA guarantees to ensure parallel B2B and D2C performance.
