Evaluate service-level performance (pick/pack rates, cut-off times), WMS/API integrations, carrier connectivity, inventory accuracy, and scalability. Check storage resiliency for seasonal weather, cross-dock capacity, reverse-logistics processes, and how the provider maps lanes to reduce last‑mile costs and delivery time.

Sylhet typically offers lower land and labor costs than major metros, which can reduce per-pallet storage and labor-driven per-order fees. However, inbound freight to national hubs, seasonal handling needs, and asset amortization (racking, climate controls) are key drivers that determine final rates.

Road freight to Dhaka and regional highways is primary for domestic delivery; smaller regional airports and river routes support time-sensitive or bulk movements. Lead times depend on carrier frequency, road conditions during monsoon season, and cross-border customs routing for exports to northeastern India.

Require a cloud-based WMS with real-time inventory, API connectivity for order management systems, barcode scanning, returns handling, and configurable routing logic for omnichannel allocation. Confirm SLA reporting, EDI/API onboarding timelines, and support for cycle counts and lot/serial tracking if needed.

Review provider contingency plans for monsoon/flooding, insurance coverage, raised storage solutions, and historical uptime. Audit physical infrastructure (drainage, raised docks), labor continuity plans, and carrier alternatives to ensure service resilience during peak or adverse weather periods.
