Kill Bill vs OpenBRM

Kill Bill is an open-source, programmable billing platform with APIs for pricing models, subscriptions, invoices, and payment gateway integrations. It supports usage-based billing, and plugins connect its payment platform to gateways, issuing banks, and fraud tools. The web-based Kaui back-office interface lets teams configure price books and manage subscriptions and payments. Listed integrations include Stripe, Adyen, PayPal, Braintree, GoCardless, Coinbase, Avalara, and Vertex. Installation options include Docker and Tomcat; Kill Bill can run on Windows, Mac, or Linux computers, or on a Linux cloud server. Described security controls include encryption at rest and in transit, TLS communications, AES-256 stored-data encryption, audit logs, role-based access, and multi-tenant isolation. The self-hosted open-source option includes community support, but customers operate and upgrade it; paid support tiers are purchased separately for customer-managed deployments. The AWS Marketplace option is listed at ~$40/mo, plus AWS infrastructure costs. Hosted-platform pricing follows a separate commercial model. The maker describes the product as serving online businesses, customization-focused teams, startups, and growth-stage companies.

OpenBRM is an open-source billing and subscription management platform for telecom operators, ISPs, MVNOs, SaaS businesses, and enterprises. It combines recurring subscriptions, one-off charges, prepaid balances, and rated usage on customer-cycle invoices sent by email or PDF. Subscription operations cover plan changes, upgrades, downgrades, cancellation, and activation, with provisioning hooks; inventory tracks SIMs, MSISDNs, modems, and IP pools. An ecommerce storefront supports subscription sales with recurring billing and payment processing. OpenBRM incorporates the OpenRate rating engine, which the site says handles around 1,000 CDRs per second and accepts delimited, fixed-length, binary, TAP, and ASN.1 formats. Its CRM supports quotes, service 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. Saralam Technologies develops and supports OpenBRM and offers implementation, integration, and custom development services.
