ISP Management & Billing ERP system

OVERVIEW

🚀 Built and launched **GESN-NET** — an ISP Management & Billing ERP system designed to make internet service operations simpler, smarter, and more organized. Managing an ISP involves much more than just connecting customers. There are subscriptions, billing cycles, payments, expenses, invoices, reports, and countless operational details. So I built a platform that brings everything together in one place. 🛠️ **What I built:** 📌 **Customer Management** * Manage subscriber accounts from a single dashboard * Track packages, monthly fees, connection details, routers, and IP addresses * Handle active, inactive, and disconnected customers 📌 **Automated Billing System** * Generate monthly bills for active subscribers * Track payment status and collection history * Create professional branded PDF invoices instantly 📌 **Business Analytics** * Revenue tracking * Expense monitoring * Outstanding dues overview * Profit & loss insights through interactive dashboards 📌 **Admin & Security** * Secure authentication with Clerk * Role-based access control * Protected ERP modules for authorized users only ⚙️ **Built With:** Next.js 15 + React 19 TypeScript Tailwind CSS MongoDB + Mongoose Clerk Authentication Recharts jsPDF & html2canvas 💡 **Some challenges I enjoyed solving:** → Designing a scalable ERP architecture → Building automated billing workflows → Turning raw business data into meaningful insights → Creating a smooth experience while keeping performance high This project was a great opportunity to combine frontend engineering, backend architecture, database design, and real-world business logic into one complete application. Every project teaches something new. This one definitely did. 🚀 More improvements and features are already on the way. 🔧 #NextJS #React #TypeScript #FullStackDevelopment #MongoDB #ERP #SaaS #WebDevelopment #SoftwareEngineering
