Prioritize WMS capability and API connectivity, measured pick/pack accuracy, inventory visibility, SLA specifics (order cutoffs, lead times), value‑added services (kitting, reverse logistics), and scalable space. Confirm carrier relationships and last‑mile options to ensure consistent delivery performance as volumes grow.

Transportation costs here are driven by distance to major markets, road quality, and LTL consolidation frequency. Proximity to primary highways reduces empty miles and fuel spend; reliable carrier schedules and consolidation lowers per‑unit freight cost, improving landed cost when combined with lower warehousing rates.

Essential features include real‑time WMS with barcode scanning, cycle counting, temperature‑controlled zones (if applicable), racking for SKU density, secure yard access, and integrations for order management and marketplaces. These reduce errors and accelerate fulfillment throughput.

Negotiate transparent pricing (fixed vs variable), clear SLA metrics (OTD, pick accuracy, inventory accuracy), minimum notice periods, chargeback rules for SLA breaches, and regular performance reporting. Include clauses for volume scaling, seasonal rate adjustments, and technology access rights (WMS/API).
