About Our Client

A mid-sized U.S.-based retail startup aimed to launch a multi-vendor e-commerce platform connecting independent sellers with online shoppers. They envisioned a feature-rich, scalable SaaS product to simplify store creation, order management, and payment processing, all under one roof.

Challenge

The client’s goal was ambitious: to empower vendors with a plug-and-play online store builder, while also delivering a seamless shopping experience to customers. However, they faced several challenges:

  • No existing system to onboard or manage vendors at scale.
  • Manual product listings and order processing slowed growth.
  • Limited analytics for vendors and poor buyer engagement.
  • Payment delays are due to a lack of real-time settlement logic.
  • Required a scalable architecture to handle traffic surges and SKU expansion.

They needed a custom SaaS e-commerce solution that combined the flexibility of platforms like Shopify with the simplicity and speed of a unified cloud system.
