🚀 Build and try the finished Invoice Generator: https://invoice.titussimplifies.com/ 🌐 More AI tutorials, tools and projects: https://www.titussimplifies.com/ In this video, I build a complete professional Invoice Generator web app from scratch using AI and vibe coding. This is a full step-by-step build — not just a demo. We start with an empty project and build the application together until we have a polished web app that can create real invoices and export them as professional PDFs. By the end of the video, our Invoice Generator can: ✅ Add business/company details ✅ Add customer/client information ✅ Create invoice numbers ✅ Set invoice and due dates ✅ Add multiple products and services ✅ Calculate quantity × price automatically ✅ Calculate subtotal automatically ✅ Add VAT / tax ✅ Apply percentage or fixed discounts ✅ Calculate the final invoice total ✅ Select different currencies ✅ Add payment information ✅ Add invoice notes ✅ Upload a business logo ✅ Preview the invoice live ✅ Save invoice information locally ✅ Download the finished invoice as a PDF ✅ Work on desktop and mobile ✅ Deploy the finished app online We keep the project intentionally simple. There is no authentication, no database, no paid API and no complicated backend. The goal of this tutorial is to show you how much you can build with AI even if you're still learning web development. TECH USED: • React • TypeScript • Vite • CSS • Local Storage • jsPDF • html2canvas • GitHub • Vercel We also deploy the finished application and connect it to a custom domain. 🔗 TRY THE FINISHED APP https://invoice.titussimplifies.com/ 🔗 FIND MORE OF MY AI PROJECTS & TUTORIALS https://www.titussimplifies.com/ If you follow along, try building your own version instead of copying everything exactly. Change the design, add your own features and use the project to understand how modern web applications are put together.
