The 5 best usage-based billing solutions for developers in 2026
Blog post from Knock
As SaaS companies increasingly adopt usage-based pricing models, having a robust billing infrastructure is essential to manage complex metering, real-time usage tracking, and flexible pricing systems. Knock emphasizes the importance of choosing the right platform to support billing by volume, such as API calls or data processed, to ensure scalability. The evaluation of popular billing solutions, including Orb, Lago, Metronome, Chargebee, and Zuora, considered factors like developer experience, pricing flexibility, integration capabilities, and scalability. While platforms like Stripe offer usage-based billing, they may fall short in handling per-customer adjustments, supporting multiple billing providers, and maintaining a single source of truth for subscription data. Knock also highlights its product's capability to manage efficient customer communication regarding billing through sophisticated, multi-channel notification workflows. This ensures critical updates reach customers, maintaining awareness without overwhelming them, as demonstrated in Vercel's case study.
