This is the software we use every day to run Nylabs. It tracks clients and leads with a full activity log and follow-ups. Invoices export to PDF and reports filter down to CSV. A separate admin console handles users and roles with an audit history behind everything.
The demo is the production interface rebuilt to run entirely in your browser. It ships with sample data you can edit and reset. Nothing is stored and nothing leaves the page. In a real engagement the same system runs on a real database with sign-in and audit logging.
