Prioritize location relative to target customer zones and carrier lanes, WMS and API integration, SLA-backed pick-and-pack accuracy, inventory visibility, onboarding timelines, and transparent pricing (storage, throughput, and value-added services). Confirm labor flexibility for peaks and clear KPIs for returns management.

Proximity to highways, regional rail ramps, and parcel/LTL sortation reduces line-haul and last-mile time, lowering zone charges and enabling shorter delivery promises. Strong carrier density supports better negotiated rates and more predictable cutoffs for same- or next-day service.

Require a modern WMS with real-time inventory, API/EDI integrations to your OMS, batch/lot tracking, configurable pick strategies, returns processing, and capabilities for kitting or light assembly. Ask for proof of performance on SLA adherence and inventory accuracy.

Balance reduced delivery time and customer experience against higher rent and labor. Model landed cost: inventory carrying, transport, zone pricing, and potential service uplift. Consider hybrid strategies (zone inventory + regional hubs) or outsourced cross-dock to optimize costs and speed.

Assess local labor availability and wage trends, peak-season labor pools, and any regional permitting or environmental constraints on facility expansion. Verify 3PL contingency plans for seasonal surges, temporary workforce sourcing, and compliance with storage and transport regulations.
