Prioritize WMS/API integrations for real‑time inventory, order accuracy and cycle time KPIs (pick/pack lead time, inventory accuracy, OTIF). Assess returns processing, SLA penalties, onboarding timelines, reporting cadence, and the 3PL’s carrier connectivity and last‑mile partners to ensure consistent customer experience.

Shorter transit distances from Delhi reduce fuel and line‑haul costs and increase delivery windows for same‑ or next‑day options in the NCR and neighbouring states. Dense carrier presence lowers rates and improves pickup frequency, while proximity to major highways and air freight gateways speeds replenishment and lowers safety stock needs.

Compare base storage rates, slotting and density assumptions, inbound/outbound handling fees, pick/pack and packing materials, peak season labor surcharges, transportation accessorials, and any WMS/access fees. Include landed cost modeling and service level tradeoffs to understand true cost‑to‑serve.

Request historical performance data for peak periods, inspect labor flexibility plans, review WMS scaling and API throughput, confirm contingency space and cross‑dock options, and run a short pilot with agreed KPIs and penalties. Check references for similar SKU complexity and order velocity.
