Orb

Orb is a modern billing platform purpose-built for usage-based and hybrid pricing, helping software companies turn raw product usage into accurate invoices and reliable revenue. As pricing models grow more sophisticated — combining subscriptions with consumption, seats, credits and tiers — legacy billing systems and home-grown solutions buckle under the complexity. Orb provides a flexible, developer-friendly engine designed from the ground up for exactly this challenge, so companies can bill correctly no matter how creative their pricing gets.

At its core, Orb ingests usage events from your product, accurately meters and aggregates them, and applies your pricing logic to produce invoices that customers can trust. It supports complex scenarios — tiered and volume pricing, prepaid and postpaid credits, minimums and commitments, proration and mid-cycle changes — without forcing you to hard-code brittle billing logic into your application. Crucially, it emphasizes accuracy and auditability, giving finance and engineering teams confidence that the numbers are right and traceable, which matters enormously when billing errors directly cost revenue and trust.

Orb also bridges the gap between engineering and finance, providing the data, reporting and integrations both sides need: clean revenue recognition data, syncing with tools like accounting and CRM systems, and visibility into usage and revenue trends. Its developer-centric design — robust APIs, reliable event ingestion and flexibility — makes it a favorite for fast-growing, technically sophisticated companies, including many in AI and infrastructure where usage-based billing is essential. For organizations that have outgrown simple subscription billing and need a system that can keep pace with evolving pricing while remaining accurate and scalable, Orb offers a powerful, purpose-built solution that takes one of the hardest parts of running a software business and makes it dependable.
