What Orb is

Orb is a billing platform for businesses that charge by usage, recurring invoices, or a mix of pricing models. It can combine usage charges, fixed fees, and per-seat charges in one plan, and supports event ingestion through its API and S3 at volumes such as 250K+ events per second. Every plan includes Orb Invoicing for generating and delivering invoices, along with integrations for invoicing, accounting, finance, and tax. The service also supports online payments, reminders, multi-currency invoices, and a client portal. Core includes real-time event ingestion and alerts, automated price changes, and hybrid and usage-based billing. Advanced adds data warehouse sync, Salesforce and NetSuite integrations, customer hierarchy, and premium support; Enterprise adds enterprise-grade SLAs and dedicated support. Orb says its pricing is based on billings and events, with a platform fee for Advanced and Enterprise. It is paid, has no free plan, and lists pricing on request. Orb is made by a company headquartered in San Francisco, California.
