reaatech/invoicing-app

This is a desktop invoicing application built with Electron, React, and TypeScript that manages customers, products, and invoices with email delivery and PDF generation. You would use it to handle invoicing for a freelance or contracting business without paying subscription fees or per-invoice charges. The application stores all data locally in SQLite, generates PDFs via Puppeteer with Mustache templates, and sends invoices through SMTP email—all running as a standalone desktop app with no external service dependencies.
