I built Invovanta to help freelancers and small businesses manage clients, create professional invoices, track payments, and keep their business information organized in one place. It also includes features like invoice PDFs, dashboards, client management, and AI-powered receipt extraction. I’d genuinely appreciate feedback from the HN community. What would you improve, remove, or add?
