Client Introduction

A major Australian retailer with over 200 physical stores and a disjointed online presence. Their website, built on an aging monolithic platform, was completely disconnected from their in-store POS and inventory systems. This created a frustrating experience for customers and massive operational inefficiencies for the business. They had an annual revenue of AUD 400M.

Problem and challenges in FinTech

Problem

The client could not offer modern retail experiences like Buy Online, Pick-up In-Store (BOPIS), ship-from-store, or unified customer loyalty programs. Their inventory data was siloed, leading to stockouts online when products were available in stores, and vice-versa. They needed a unified commerce platform to create a seamless experience across all channels.

Key Challenges

Migrating a massive, complex system with zero downtime

Integrating with dozens of disparate systems: POS, inventory management, warehouse management (WMS), and CRM.

Ensuring compliance with strict financial regulations

Creating a real-time, unified inventory system accessible to both the website and stores.

Integrating with dozens of third-party financial institutions

Building a reliable and user-friendly "Click & Collect" (BOPIS) workflow.

Retraining their internal team to manage the new cloud-native environment

Migrating millions of customer loyalty profiles into a single, unified system.

Our Solution for FinTech

Our Solution

We leveraged our Extract-Transform-Load / Integration Pod and MEAN / MERN Full-Stack Pod to architect a headless, API-driven solution that placed a central Order Management System (OMS) at its core.

🧠 Centralized OMS

We implemented a powerful OMS to act as the "brain" of the operation, orchestrating orders, inventory, and fulfillment across all channels.

🔗 API Integration Layer

We built a comprehensive suite of APIs to connect the OMS with all of the client's existing systems (POS, WMS, CRM, etc.), creating a single, unified data pipeline.

🛒 Headless Commerce Engine

We used BigCommerce as the headless commerce engine to manage the product catalog and promotions.

📱 Custom Frontend & In-Store Apps

We developed a React-based website for customers and a separate tablet-based application for in-store staff to manage "Click & Collect" orders and access the unified inventory.

Implementation and Execution

Established a secure site-to-site VPN

Systems Audit & Architecture

A deep dive into all existing systems to map data flows and design the final API-first architecture.

Parallel Environments Setup

OMS Implementation & Configuration

Set up and customized the core OMS to handle the client's specific fulfillment logic.

Kafka for event-driven communication

API Development & Integration

The core of the project, building and testing the dozens of API endpoints needed to unify the systems.

Monitoring and observability stack

Frontend & In-Store App Development

Developed the user-facing applications in parallel with the API development.

Automated performance and penetration testing

Pilot Program

Rolled out the solution to a small group of 10 stores to test and refine the BOPIS workflow in a real-world environment.

Final cut-over during low-traffic windows

Full Rollout & Training

Deployed the solution across all 200+ stores and provided extensive training to staff.

Positive Outcome

📈 25% Revenue Growth Attributed to Omnichannel

The new "Click & Collect" and ship-from-store capabilities opened up significant new revenue.

💖 35% Increase in Customer Lifetime Value

Customers using both online and in-store channels were proven to be more loyal and spend more over time.

📦 Drastic Reduction in "Out of Stock" Issues

The unified inventory system allowed them to fulfill online orders from store stock, capturing sales that would have otherwise been lost.

🚀 Improved Operational Efficiency

The automated workflows and single view of data significantly reduced manual work and communication overhead between teams.
