Prioritize SLA performance (order lead time, accuracy), technology compatibility (WMS/APIs), network reach (regional carriers, last-mile partners), and cost structure (storage, pick/pack, inbound handling). Also evaluate scalability for peak seasons, reverse logistics capability, and value-added services like kitting and labeling.

Geographic proximity to major arterial routes and intermodal nodes reduces lane miles to urban centers and lowers fuel and transit-time variability. Strong carrier density delivers competitive negotiated rates and more frequent pickup windows, which together shorten delivery windows and reduce per-shipment cost.

Expect line items for storage (per pallet/cubic), receiving, putaway, pick/pack, packing materials, returns processing, and transportation accessorials. To optimize costs: consolidate SKUs across fewer nodes, use zone-based inventory placement, negotiate bundled rate tiers, and measure on-costs like accuracy and chargebacks.

Confirm WMS features (lot/SKU control, batch processing), real-time inventory APIs, EDI/REST integration capabilities, and support for marketplace connectivity. Request demonstration of order-to-shipment workflows, uptime/latency SLAs, and sample data exchange to validate fulfilment routing and inventory reconciliation.
