Evaluate proximity to key transport corridors, warehouse storage density, handling rates, available labor, and scalable capacity. Verify WMS/API capabilities, order cutoffs, returns processing, and peak-season surge plans to ensure alignment with forecasted volume and service-level expectations.

Carrier coverage determines transit windows, consolidation opportunities, and freight cost tiers. Strong last-mile networks reduce final-leg costs and improve delivery predictability—look for partners with contracted courier relationships and integrated parcel rate engines to control charges.

Require a robust WMS with API/EDI integrations, real-time inventory visibility, barcode scanning, and configurable pick/pack workflows. Also assess racking, temperature control, secure storage, and automation options that match SKU characteristics and throughput needs.

Compare total landed cost models (storage, pick/pack, receiving, handling), minimums, and activity-based surcharges. Align sample volume forecasts to proforma invoices and benchmark KPIs (OTIF, accuracy, lead times). Validate contract terms for liability, audit rights, and seasonal scalability.
