Building a GST Invoice App with Next.js for Indian Businesses

GST Invoice App

I needed a simple GST invoicing tool for my freelance work. Nothing fancy, just something that generates compliant invoices.

Features

• GST Compliant — CGST, SGST, IGST support
• PDF Export — Download invoices as PDF
• Client Management — Save and reuse client details
• Dashboard — Track invoices and payments

Tech Stack

• Next.js 14 — React framework
• TypeScript — Type safety
• Tailwind CSS — Styling
• jsPDF — PDF generation

Why build this?

Every GST tool I found was:

• SaaS with monthly fees
• Overly complex for small businesses
• Not customizable

This is open source, runs locally, and does exactly what's needed.

Quick Start

git clone <repo>
cd gst-invoice-app
npm install
npm run dev
