Transforming a Traditional Retailer with a Custom Omnichannel Web & Mobile Platform

Project Overview

The client is a legacy national home goods retailer with a 40-year history and 300+ physical locations. Facing existential pressure from e-commerce giants, they needed to move beyond a “physical-first” mindset. The goal was to build a unified, custom-engineered omnichannel platform that would provide a consistent, high-end experience across web, mobile, and in-store touchpoints.

Problem

The retailer’s digital efforts were previously hindered by a fragmented and aging tech stack:

• The “Inventory Gap”: E-commerce and in-store inventory were managed by separate systems that only synced once every 12 hours. This led to a 15% inventory error rate, where customers would buy items online only to find they were out of stock in the store.

• High-Friction UX: The legacy website was slow and not mobile-optimized, resulting in a staggering 70% cart abandonment rate.

• Siloed Customer Data: There was no way to track a customer’s journey from online browsing to an in-store purchase, making personalized marketing impossible.

 

Our Solution

XenonDev engineered a Unified Headless Commerce Ecosystem:

1. Headless API-First Architecture: We decoupled the frontend from the backend using Commercetools (Commerce) and Contentful (CMS). This allowed us to build highly optimized, lightning-fast frontends for web (React/Next.js) and mobile (React Native) while sharing a single source of data.

2. Real-Time Event-Driven Sync: We implemented an event-driven architecture using Apache Kafka. Every time a barcode was scanned at a physical POS, an event was fired, updating the online inventory levels globally in under 200 milliseconds.

3. Advanced Fulfillment Logic: We built a custom fulfillment engine that enabled complex “Modern Retail” workflows, including BOPIS (Buy Online, Pick Up In-Store), BORIS (Buy Online, Return In-Store), and intelligent ship-from-store routing to minimize shipping costs and times.
