Evaluate SLA commitments (order lead time, pick/pack accuracy), inventory visibility through WMS integrations, carrier variety for last-mile coverage, peak-season capacity, and scalability. Also compare onboarding timelines, chargeback policies, and reporting granularity to align with your service-level targets.

Tanana’s logistics profile includes river/road links and limited air service that create predictable but seasonal routing windows. Expect reliance on regional LTL and consolidated parcel flows; carrier selection should prioritize operators with northern routing experience and contingency plans for seasonal disruptions.

Confirm WMS interoperability, pick-and-pack accuracy, kitting/assembly, returns processing, cross-dock capacity, and any cold-chain options. Validate inbound receiving SLAs, security controls, and reporting cadence to ensure the 3PL supports your SKU mix and order profiles.

Use a cost-to-serve model that combines warehousing fees, inbound/outbound freight, safety stock carrying cost, and expected service levels. Run network scenarios to compare central vs. regional placement, accounting for seasonal transit variability and the impact on fill rates and expedited freight spend.
