OpenBRM
What it is
OpenBRM is an open source billing and subscription management platform for telecom providers, ISPs, MVNOs, SaaS businesses, and enterprises. It combines recurring subscriptions, one-off charges, prepaid balances, and rated usage on customer-cycle invoices delivered by email or PDF. Subscription operations include plan changes, upgrades, downgrades, cancellations, and activations, with provisioning hooks; inventory tools track SIMs, MSISDNs, modems, and IP pools. An ecommerce storefront supports subscription sales with recurring billing and payment processing. OpenBRM integrates the OpenRate rating engine, which the site says processes around 1,000 CDRs per second and accepts several formats, including delimited, fixed-length, binary, TAP, and ASN.1. Its CRM supports quotes, tickets, bulk SMS and email notifications, and customer reminders. GUI functions are available through SOAP and REST APIs. The self-hosted package, including the rating engine and ecommerce component, has no licence fee. A hosted SaaS trial is also listed as free, with no trial duration stated; the hosted option's price is not published. Saralam Technologies develops and supports the platform and offers implementation, integration, and custom development services.
