The Challenge

As Novex expanded its retail operations, shipping orders from four regional warehouses became complex. Generic plugins crashed during flash sales, miscalculated delivery dates, and required warehouse staff to manually sort hundreds of multi-item orders every morning.

Strategic Solution

Yeelo Tech developed a custom Shopify solution built for high-volume commerce:

  1. Intelligent Order Routing: Automatically routes customer orders to the closest warehouse with available stock, speeding up delivery and cutting shipping costs.
  2. Native Checkout Enhancements: Shows shoppers real-time, accurate delivery dates right at checkout, improving purchase confidence.
  3. High-Volume Stability: Built to handle thousands of simultaneous transactions effortlessly during Black Friday and seasonal promos.

Business Results

During peak holiday sales, the system processed over 1,200 orders per minute without a hitch. Inventory errors fell to zero, customer support inquiries regarding delivery dates dropped by 54%, and the operations team saved 20+ hours of manual sorting weekly.

Key Production Deliverables Included:

  • ✓ Custom Shopify app directly embedded into store operations
  • ✓ Checkout extension displaying exact delivery estimates for shoppers
  • ✓ Automated multi-warehouse inventory and order routing
