Blue Onion

It ingests contracts, orders, invoices and usage data from upstream billing and CPQ systems, applies configurable revenue rules, and produces journal entries, waterfalls and audit-ready reports.

Founded by former Asana engineers who were tired of pricing changes taking months, Orb powers billing for companies like Vercel, Replit, Pinecone, and Perplexity.
