Institutional-grade, zero-backend, privacy-first invoice generator built for Indian financial consultants, freelancers, and small businesses. Generates pixel-perfect, GST-ready PDF invoices entirely in the browser — no servers, no sign-ups, no data leaving your machine. Features 20+ professional templates via a registry-based TemplateEngine, Indian FY numbering (INV/FY25-26/0001), UPI QR code generation, multi-profile sender management, and full client CRM — all stored in localStorage with JSON export/import backup.
