Best Usage-Based Billing Platforms for AI Infrastructure

AI infrastructure companies need billing systems that can convert variable activity such as tokens, GPU hours, API requests, and compute usage into accurate charges while supporting hybrid pricing, prepaid credits, enterprise commitments, customer visibility, invoice adjustments, and financial reporting. The comparison reviews Orb, Metronome, Stripe Billing, Lago, Chargebee, m3ter, Maxio, Amberflo, Credyt, and Alguna, noting that their strengths vary among granular metering, subscription management, open-source deployment, AI cost attribution, prepaid wallets, enterprise contracting, and quote-to-cash workflows. Orb is presented as a broad revenue infrastructure platform with retained raw usage events, SQL-based metrics, dimensional pricing, historical pricing simulations, credits, invoicing, and finance integrations, while other platforms offer differing combinations of these capabilities. The billing market has also consolidated, with Stripe acquiring Metronome in January 2026, Salesforce acquiring m3ter in July 2026, and Adyen acquiring Orb in July 2026. Selecting a platform requires assessing usage-data retention, event attribution, pricing flexibility, customer spend controls, total implementation and operational costs, unit economics, and integration with collections, revenue recognition, ERP, and CRM systems.
