Designed and developed a Smart Billing Web Application that streamlines the entire billing process for businesses. The system allows staff to generate bills quickly and easily with a simple, clean interface. Once a customer completes payment, an automated WhatsApp message is instantly sent to the customer with their bill details — eliminating manual follow-ups and improving customer experience. The application includes a feature-rich Admin Panel for full customization — managing products, prices, users, and business settings. Built with a modern tech stack and deployed on Vercel for fast, reliable performance.
