Prioritize location relative to major highways and Islamabad, dock and bay capacity, storage systems (racking, ambient/cold), labor availability, and value‑added services (kitting, returns). Also verify carrier integrations, SLAs for pick/pack times, and scalability for peak seasons to align with sales forecasting.

Transit times influence inventory safety stock and last‑mile costs. Proximity to express courier hubs and reliable trucking reduces transit variability and enables tighter delivery windows, lowering expedited fees. Evaluate common lane lead times and carrier performance history to quantify cost-to-serve by zone.

Key drivers: storage density (m2 or pallet locations), pick/pack labor and throughput, inbound/outbound handling, value‑added services, and transportation. Model costs by combining per‑unit handling rates, storage per cubic meter, seasonal labor premiums, and average outbound parcel costs to calculate landed fulfillment cost.

Require WMS with real-time inventory, EDI/API integrations for order flows, returns management, and reporting dashboards. SLAs should include order accuracy, on-time shipment rate, receiving lead time, and inventory reconciliation frequency. Confirm audit capabilities and data export for performance monitoring.
