Recurly is a subscription management software known for its user-friendly interface and capabilities in subscription billing and revenue recognition, but it struggles with advanced features like usage-based billing. For businesses seeking alternatives, Lago, an open-source platform, offers flexible billing models such as postpaid and usage-based billing while integrating with various payment processors and CRM systems. Stripe Billing, part of the Stripe ecosystem, provides a straightforward solution with seamless integration for businesses already using Stripe, though it lacks advanced billing flexibility. Metronome caters to small and mid-sized businesses desiring a low-code approach for basic usage-based billing, while Zoho Subscriptions integrates well within the Zoho ecosystem for small enterprises. Paddle provides an end-to-end solution with global tax compliance, while Zuora supports enterprises with complex billing needs through advanced features and integrations. Building a homegrown billing system offers complete customization but involves high development costs and maintenance. Each alternative has its pros and cons, catering to different business sizes and requirements, with Lago being a strong contender for those needing a highly adaptable and transparent billing solution.
