Lemon Squeezy vs OpenBRM

Lemon Squeezy is an all-in-one platform for SaaS businesses selling digital downloads, subscriptions, and software licenses. It says it acts as merchant of record for digital sales taxes and compliance. Merchants can embed no-code checkout forms on an existing site or share checkout links; its no-code and API solutions support 20+ payment methods and global bank payouts. Subscription billing can run weekly, monthly, or yearly, with management for upgrades, downgrades, cancellations, and free trials. The platform can issue software license keys and provides signed, throttled download links. Lemon Squeezy says its fraud protections use machine learning and real-time analytics to identify suspicious transactions. Its REST API documentation states a limit of 300 calls per minute, and documented integrations include ConvertKit, Mailchimp, and Zapier. Ecommerce has no monthly charge and costs 5% + $0.50 per transaction when sales are generated, with sales tax collection and remittance included. Email marketing is free for up to 500 subscribers. Lemon Squeezy was founded in 2019.

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.
