Key criteria include transparent SLAs and KPIs, WMS/TMS integration, inventory accuracy, pick/pack cycle times, returns handling, and capacity scalability. Consider integration and operational readiness:

• Real-time inventory visibility and API connectivity
• Flexible labor models for peak periods
• Value-added services such as kitting and labeling

Alor Setar's access to the North–South Expressway, nearby airport and short road links to Penang improve lead times to key northern and central markets. A higher density of LTL and trucking options lowers per-shipment rates; limited airfreight capacity can raise premiums. Model modal mix, transit time variance, and carrier density when forecasting fulfillment costs and service levels.

Require a cloud-based WMS with API or EDI connectivity for order routing, real-time inventory, lot/serial traceability, returns management, and reporting. TMS integration should support rate shopping, multi-carrier routing, and shipment visibility. Also confirm support for barcode/RFID workflows, batch processing, and standardized KPI dashboards for operational transparency.

Assess local labor pools, prevailing wage rates, and seasonal workforce sources, and review lease terms, utility costs, and taxes. Use a checklist to compare partners:

• Average pick rates and labor productivity metrics
• Available racking, mezzanine, and temperature-controlled space
• Options for short-term expansion, subleasing, or flexible bay usage
