OpenBRM is an open source billing and revenue management platform for telecom, subscription, and usage-based businesses. It handles the full cycle — customer accounts, products and plans, orders, rating, invoicing, and payments — in one system you can run and extend yourself.

Built on a modern Java stack (Java 17, Grails 6, Spring Batch, PostgreSQL), OpenBRM is a practical alternative to proprietary BRM suites like Oracle BRM. It supports payment gateway integration, batch billing runs, web service APIs, and configurable workflows for provisioning and account management.
