As the tech industry evolves with AI-powered services and complex SaaS offerings, billing strategies are shifting towards more flexible models to better align with customer usage and value delivery. Usage-based billing, which ties customer costs directly to their consumption, has emerged as a core strategy, enabling faster revenue growth compared to traditional subscription models. Companies are increasingly adopting hybrid billing models that combine subscriptions with usage-based elements to balance predictable revenue with growth potential. Credit-based and pay-as-you-go models offer further flexibility, especially for AI and data-intensive services, by allowing customers to manage costs more effectively based on their specific usage patterns. Successful implementation of these models requires robust metering and billing systems to accurately track and invoice consumption, ensuring transparency and scalability. Companies like Lago provide comprehensive platforms that support various billing strategies, helping businesses adapt to the changing landscape and capitalize on new monetization opportunities.
