Commercial Projects

This project implemented EDI integration with a new retail partner to enable automated and reliable electronic document exchange between the retailer, supplier ERP system, and warehouse management system.

The integration supported the end-to-end order lifecycle, including purchase order processing, inventory visibility, warehouse fulfillment, shipment notification, and invoicing through standardized EDI transactions.

Electronic Data Interchange is a critical component of modern trading and e-commerce operations. It allows trading partners to exchange business documents electronically in standardized formats, eliminating manual data entry and improving transaction speed, accuracy, and operational efficiency.

For high-volume retail and e-commerce channels, EDI supports automated order processing, real-time inventory visibility, faster warehouse fulfillment, accurate shipment notifications, and automated invoice transmission. In omnichannel retail environments, EDI provides scalable system-to-system communication that reduces manual errors, improves service levels, and supports retailer compliance requirements.

EDI Workflow

Retailer → Supplier → Warehouse → Supplier → Retailer

• Supplier sends 846 Inventory Advice when required.
• Retailer sends 850 Purchase Order.
• Supplier sends 855 Purchase Order Acknowledgment.
• Supplier converts order details into 940 Warehouse Shipping Order for the 3PL warehouse.
• Warehouse processes picking, labeling, and shipping.
• Warehouse sends 945 Warehouse Shipping Advice after the product is shipped.
• Supplier generates and sends 856 Advance Ship Notice with tracking information.
• Supplier sends 810 Invoice to the retailer.

Planning → Mapping & Development → Testing → Deployment → Maintenance

• Planning: Define project requirements with the retailer and internal stakeholders; confirm document standards, mandatory fields, packing standards, label requirements, and business rules; define the integration architecture between the EDI platform, ERP, and WMS.
• Mapping & Development: Configure EDI mappings for 850, 860, 997, 846, 855, 856, 810, 940, and 945; develop AS2 or SFTP connectivity with the retailer; integrate supplier ERP and warehouse management systems; configure packing list and shipping label templates.
• Testing: Complete EDI connectivity testing, document mapping validation, unit testing, warehouse integration testing, and end-to-end order flow/UAT.
• Deployment: Prepare the production cutover plan, execute go-live migration, monitor initial transactions, and resolve post-go-live issues.

This commercial program supported the distribution of energy-saving products through more than 1,000 Dollar Tree stores across the United States.

Products such as power strips, light bulbs, and door sweeps were sold to end users at affordable prices, helping customers reduce energy usage and lower utility costs. The utility company then issued rebates based on verified sales records from Dollar Tree.

• Utility Rebate Program Workflow

  
  Negotiated annual program budgets with utility partners.
• Forecasted and maintained inventory across more than 1,000 Dollar Tree stores in the United States.
• Arranged deliveries from 3PL warehouses to retailer distribution centers.
• Supported demand forecasting and replenishment planning.
• Prepared sales-based reports for utility rebate validation.

This project supported ongoing sales and fulfillment operations for more than 800 hotels and hostels across the United States.

The program required close coordination with sales representatives, warehouse teams, logistics providers, and factories in China to maintain inventory availability and deliver products to customer sites through FTL, LTL, and small parcel shipments.

• Supported more than 800 hospitality customers across the United States.
• Managed inventory and forecast planning in the 3PL warehouse.
• Arranged FTL, LTL, and small parcel shipment options.
• Maintained sales plans and aligned inventory levels with forecast demand.

This project supported an MPLS-to-SD-WAN network transformation for a freight forwarder with multiple remote sites.

A global freight forwarding company operating 20 branch offices in China experienced increasing network congestion and high operating costs due to its centralized MPLS architecture.

All remote offices were required to route traffic through the Shanghai data center. This created significant bandwidth bottlenecks and limited the deployment of new collaboration systems such as Cisco Webex video conferencing.

The objective was to modernize the network architecture by migrating from a fully centralized MPLS topology to a hybrid SD-WAN architecture, improving performance, reducing cost, and enabling local internet access for branch offices.

• MPLS bandwidth bottlenecks.
• High MPLS operating costs.
• Lack of local internet access due to centralized security controls.

• Deploy FortiGate firewall appliances at each remote office.
• Maintain MPLS connectivity for critical traffic.
• Use IPsec VPN over internet links for non-critical traffic.
• Enable local internet breakout for branch offices.

Proposed SD-WAN solution topology

This project supported an IP Transit connectivity enhancement for a leading mobile network operator in Hong Kong serving approximately 3.5 million mobile subscribers.

Due to rapid growth in mobile data traffic and increasing cross-border internet usage, the operator experienced capacity bottlenecks and latency issues in its existing connectivity with China networks and international upstream carriers.

To improve network resilience, routing flexibility, and international connectivity performance, the operator initiated an IP Transit upgrade project.

• Increase international internet capacity.
• Eliminate congestion between Hong Kong and overseas networks.
• Improve routing efficiency and latency for China and international traffic.
• Enhance network resilience through redundant transit paths.

• Deploy dual-path 10Gbps IP Transit connectivity to ensure high availability.
• Advertise IP prefixes to upstream carriers.
• Optimize routes for international and China-bound traffic.
