Project Overview
I developed a Point of Sale (POS) system that streamlines retail and business operations by handling Sales, Purchase, Inventory, Accounts, Reports, and User Management. The system was designed to be scalable, fast, and reliable, allowing businesses to track every transaction, manage stock in real time, and generate financial insights.
Problem
Businesses often face challenges in managing daily operations due to manual bookkeeping, inconsistent stock updates, and lack of real-time financial reporting. This results in errors, lost revenue opportunities, and reduced efficiency.
Solution
To overcome these challenges, I built a modern POS system with the following capabilities: Seamless Sales & Purchase management with invoice generation. Real-time Inventory tracking with low-stock alerts. Integrated Accounting module for cashflow, ledgers, and expense tracking. Customizable Reports (sales, purchases, profit/loss, tax, inventory aging). Role-based User Management for Admins, Cashiers, and Accountants.
Major Challenges Faced
Inventory Synchronization
Keeping stock updated in real-time across multiple retail branches was challenging. Delayed sync could result in overselling or inaccurate stock reporting.
Data Security & Fraud Prevention
Protecting customer transactions and sensitive business data against unauthorized access, while ensuring PCI-DSS compliance, was a top priority.
Real-Time Sales & Reporting
Generating instant sales reports and dashboards for business owners without slowing down the transaction process was technically demanding.
Solutions Implemented
ASP.NET Core 8 with Clean Architecture
Designed the POS backend using ASP.NET Core 8 and Clean Architecture. This modular design ensured scalability, easier maintenance, and faster feature rollouts like billing, discounts, and stock updates.
Results:
- • Simplified maintenance and reduced technical debt
- • Faster integration of new POS features
- • Future-proof architecture for business expansion
Cloud Hosting & CI/CD
Deployed the POS on cloud infrastructure to ensure 24/7 availability. Configured CI/CD pipelines for faster releases, auto-scaling, and regional redundancy.
Results:
- • Seamless scalability during high-traffic sales
- • Reduced downtime with load balancing
- • Faster, automated deployment cycles
SQL Server & Real-Time Inventory
Implemented SQL Server for transaction reliability and structured data. Developed real-time inventory management to prevent overselling and maintain accurate stock across multiple retail outlets.
Results:
- • Accurate inventory tracking across branches
- • Reduced losses from stock mismanagement
- • Improved decision-making with real-time data
Real-Time Chat with SignalR
Integrated a SignalR-powered chat system for instant communication between store staff and head office/admins. Used for technical support, approvals, and quick decision-making.
Results:
- • Faster resolution of store-level issues
- • Direct communication between staff & admins
- • Increased efficiency in daily operations
