Evaluate carrier transit maps and delivery zones, required SLAs (order cycle, OTIF), WMS/API compatibility, transparent volumetric pricing, minimums, and peak-season scalability. Prioritize partners with proven parcel and LTL relationships, clear reporting, and a demonstrated onboarding process for inventory and EDI/API integrations.

Expect direct interstate access via the I-55 corridor, regular parcel and LTL services feeding St. Louis and Memphis lanes, river-port transload options for bulk freight, and nearby rail corridors. These connections enable mixed-modal routing to reduce transit times and freight costs across the Midwest and Southeast.

Lower industrial rents and competitive labor rates improve per-order economics versus larger metros, while proximity to regional consumer hubs shortens transit windows. Assess local labor availability for peak periods, facility flexibility for slotting or cross-docking, and whether the 3PL can scale headcount and space quickly.

Negotiate explicit SLAs for order cycle time, inventory accuracy, OTIF, returns handling, and chargebacks. Require WMS integration, daily reporting, contingency plans for capacity spikes, transparent billing, audit access, and defined exit or remediation clauses tied to KPI performance.
