Modern technology companies are navigating a complex billing landscape as pricing models evolve from simple subscriptions to more intricate usage-based and hybrid approaches, with over 60% of SaaS and AI firms now employing at least one consumption-based model. Billing platforms play a crucial role in this transition, with advanced systems like Lago Cloud supporting real-time metering, pay-per-use models, and automated invoice generation to enhance efficiency and minimize manual errors. The adoption of usage-based billing is linked to significantly higher net revenue retention, as evidenced by industry benchmarks. Lago Cloud exemplifies a modern solution, offering robust performance at scale, comprehensive integration capabilities, and the flexibility to handle various pricing structures, including prepaid credits and custom contract terms. Additionally, Lago provides an open-source, self-hosted option for companies needing full control over their billing infrastructure due to compliance or data residency needs.
