Billing infrastructure shouldn't be a black box. Built in the open for speed, clarity, and control.

Meet QUANTUM BILLING :

QuantumBilling is a Phoenix LiveView application for Indian business billing: clients, GST invoices, document templates, credit/debit notes, e-way bills, recurring billing, payment links, reports, and compliance reminders.

It uses Elixir, Phoenix, PostgreSQL, and Oban. Business data is being separated into PostgreSQL schemas, with shared accounts and business memberships in `public`.

QuantumBilling: Where precision invoicing meets transparent, open-source engineering.
