Billsby vs OpenBRM

Billsby manages subscriptions, recurring billing, invoicing, and customer lifecycle tasks. It groups subscriptions into products, plans, and cycles that define what is offered, its pricing, and billing frequency. Pricing options include flat fee, per unit, volume, tiered, and ranged models. Usage billing supports metered allowances, real-time API updates, and manual adjustments. Checkout and account-management modals can be added to a website with as little as two lines of code. Failed or declined payments enter dunning flows intended to address payment issues and recover customers. Billsby works with payment gateways but is not itself a gateway. Core costs $45 a month, plus 0.4% on revenue exceeding $15,000/mo; Pro costs $135 a month, plus 0.5% on revenue exceeding $30,000/mo. Billsby says it supports usage-based billing, tax automation, multi-currency billing, and a customer billing portal. It is available via API and web, and is headquartered in London, United Kingdom.

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.
