Prioritize WMS functionality and integration (APIs/EDI), pick & pack throughput, inbound receiving SLA, dock and staging capacity, returns processing, and value‑added services (kitting, light assembly). Verify peak‑season scalability, IT connectivity for inventory visibility, and carrier partnerships for last‑mile and regional lanes.

Model variable and fixed costs separately: land/rent and labor tend to be lower, but factor in local fuel and drayage to Gulf ports, handling fees, utilities, and inventory carrying. Include service fees for pick/pack, inbound inspection, cross‑dock, and contingency for seasonal volume spikes when comparing TCO across locations.

Confirm access to major highways serving Gulf ports and inland markets, availability of regional and national truck carriers, container drayage providers, and last‑mile networks. Review carrier LTL and FTL capacity, typical transit times to key customers, and intermodal options if export rail or port rail services are relevant to your lanes.

Ensure your 3PL provides licensed customs‑broker support, bonded storage options if needed, correct tariff classification and documentation for exports/imports, and compliance with sanitary or hazardous material permits. Validate inventory reconciliation processes and audit trails for cross‑border shipments.
