Retail Brand Website & Online Store

A Kolkata-based clothing brand needed a modern e-commerce presence to move beyond Instagram-only sales. We built a full store with Razorpay, inventory management, and a clean admin dashboard.

Overview

The client had built a loyal following on Instagram but was losing sales because customers could not complete purchases without manual intervention. We designed and built a mobile-first e-commerce experience that lets shoppers browse collections, add items to cart, and check out securely in a few taps.

Use case

A customer discovers a product on Instagram, clicks the link in bio, and completes the purchase on the website. The admin receives the order, updates inventory, and ships the item — all through one dashboard.

How CCS handled this project

We ran a one-week discovery sprint with the founder to map the customer journey, then built a mobile-first storefront with Razorpay payment integration and an admin dashboard. The focus was on reducing friction between Instagram discovery and checkout.
