Prioritize transit time to customer clusters, warehouse automation and WMS integration, real-time inventory visibility, returns and reverse logistics capability, and a clear cost-to-serve model by SKU and channel. Also evaluate carrier contracts, seasonal capacity, SLA definitions, and reporting frequency to ensure alignment with service and margin goals.

Location drives zone-based parcel costs and transit time: proximity to highways, ports, and population centers lowers last-mile zones and fuel-driven surcharges. Locating near carrier hubs reduces line-haul costs and enables faster delivery windows, while cross-dock access supports consolidation for B2B shipments and reduces handling times.

Require a modern WMS with API integrations, real-time inventory visibility, barcode/RFID support, configurable pick/pack workflows, and reporting for KPIs. Automation for high-volume SKUs, reliable slotting and cycle-count processes, and exception management improve accuracy and reduce order-to-ship times.

Negotiate transparent rate cards (storage, inbound/outbound handling, value-added services), volume tiers, billing cadence, defined KPIs and penalties, capacity guarantees for peaks, insurance limits, liability for inventory loss, and clear termination and transition terms to limit cost exposure and ensure service continuity.
