The subscription billing management market is expected to reach $17.95 billion by 2030, fueled by the shift towards customer-centric, recurring revenue models in B2B SaaS and the increasing complexity of pricing models, particularly with the rise of AI and usage-based billing. Effective subscription management now involves more than just payment collection, requiring flexibility, accuracy, and actionable insights at scale. Modern platforms like Lago enable B2B SaaS companies to handle complex billing, hybrid pricing, and global compliance with precision. Key benefits include predictable cash flow, enhanced customer satisfaction, and reduced billing errors. Subscription management platforms should support various pricing strategies, offer advanced invoicing, provide real-time analytics, and be developer-friendly with robust API integrations. The rise of usage-based and hybrid pricing models, driven by AI and infrastructure demands, necessitates platforms that can deliver real-time event ingestion and elastic billing. Lago Cloud exemplifies a comprehensive solution by providing real-time metering, flexible pricing, and global compliance capabilities, helping companies build a scalable and resilient SaaS business.
