Invoice Generator App
Overview
Invoice Generator is a free mobile application designed for freelancers and small business owners who need to create professional invoices on the go. The app works completely offline, allowing users to generate invoices anywhere without depending on internet connectivity.
Challenge
The key challenge was to create a full-featured invoice creation system that could operate entirely offline while generating high-quality PDF documents that look professional. The app needed to balance functionality with ease of use on small screens.
Solution
I developed a React Native application with local storage for data persistence and an integrated PDF generation library. The app was designed with a step-by-step invoice creation flow that's intuitive on mobile screens while still allowing for significant customization of invoice templates.
