Usage-based billing platform designed for complex metered pricing models
Orb is a billing platform built specifically for companies implementing sophisticated usage-based and hybrid pricing models that go beyond what general-purpose billing tools can accommodate without custom engineering. The platform's architecture is designed around the concept of 'billing as code' — pricing models are defined programmatically using Orb's flexible primitives, enabling engineering and finance teams to implement complex metered pricing, hybrid subscription-plus-usage models, and commit-and-overage structures without billing-specific development work. Orb's event ingestion pipeline processes high-frequency usage events from applications and infrastructure, storing them in an immutable event ledger that serves as the authoritative billing record. Retroactive pricing changes, amendment workflows, and credit application are handled without data manipulation — a critical capability for enterprise B2B billing where contract changes require accurate historical recalculation. The invoice generation engine produces itemized invoices with usage detail that gives customers transparency into their charges. Real-time cost estimation APIs enable in-product cost dashboards, helping customers track spending against budget and avoid bill shock. Reporting covers usage trends, revenue by pricing component, and MRR attribution to understand which pricing model elements drive growth. The platform integrates with Stripe, Braintree, and major ERP systems. For infrastructure, AI, and API businesses with complex metered pricing where billing accuracy and flexibility are competitive differentiators, Orb provides an engineering-grade billing foundation built to handle the edge cases that emerge at scale.
