Focus on on-time pick/pack SLA, order accuracy, dock-to-stock cycle time, and inventory accuracy. Verify WMS capabilities (bin-level inventory, lot/serial tracking), real-time API/EDI connectivity, reporting cadence, and support for peak scaling and returns processing to ensure operational transparency and responsiveness.

Key drivers include storage-per-cubic-foot rates, pick-and-pack labor charges, inbound/outbound handling fees, packaging and kitting costs, and transportation accessorials. Optimization levers are SKU rationalization, slotting efficiency, batch picking, longer-term rate negotiations, and strategic inventory placement to reduce transport miles.

Same-day depends on carrier cutoffs, facility location relative to demand centers, and volume commitments. Next-day across key Tamil Nadu and nearby markets is achievable with the right dock throughput, local parcel integrations, and forward-stocking; plan facility placement and carrier SLAs against your order profile and delivery promises.

Require adequate dock doors, trailer staging, high-density racking, bulk/pallet storage, climate-controlled zones if needed, and secure yard management. Value-added services should include kitting, assembly, labeling, barcoding, EDI/API order exchange, quality inspection, and configurable reporting to support B2B order complexity.
