Prioritize WMS and API capability, SLA and reporting transparency, facility type (bonded, cold chain), slotting and automation options, cross-dock and consolidation services, proximity to major trunk routes, and local carrier integrations. Confirm scalability for peak seasons and clear pricing for accessorials to control variable costs.

Direct access to trunk roads and intermodal links reduces transit distance and handling, which shortens lead times and lowers freight spend. Strong carrier networks enable competitive rates and better last-mile coverage; consider consolidation options and cross-dock capabilities to optimize cost-to-serve for different SKU mixes.

Negotiate transparent unit costs for storage and pick/pack, volume tiers or rebates, clear accessorial definitions, minimums, and SLA credits. Include capacity guarantees for peak season, review inventory aging fees, and require periodic rate reviews tied to performance and indexation clauses where appropriate.

Request WMS feature documentation, API/EDI specifications, sample dashboards and reports, and references for prior integrations. Run integration tests, validate data mapping for orders and inventory, confirm exception workflows, and include acceptance criteria and uptime/SLA terms in the contract.
