About Orb

Orb is a commercial billing platform built around usage-based and hybrid pricing. Its pitch is that pricing should be designed and iterated as products, usage and costs change, and that billing infrastructure should not hold that work back. It targets software companies, including cloud infrastructure and AI product teams.

The platform covers three connected areas: billing (metering usage and invoicing for it), pricing (modeling, iterating on and optimizing price plans), and finance (contracts, collections and period close). Specific capabilities named on the site include granular usage tracking, backdating and backfilling of changes, spend alerts and workflow automation, and an experience kit for pricing calculators, dashboards and checkout flows.

Orb describes itself as built for scale and aligned to ASC 606 revenue recognition, with segments for enterprise, cloud infrastructure and agentic AI. It is a hosted product sold through a contact-sales motion, with documentation, a changelog and a pricing page published on the vendor site.
