What Orb is
Orb is a web and API platform for usage-based billing, hybrid pricing, and revenue workflows. Hybrid plans can combine usage charges, fixed fees, and per-seat charges. Orb describes event ingestion through API and S3 at scaled volumes such as 250K+ events per second, plus real-time alerting and automated price changes. Every plan includes Orb Invoicing for native invoice creation and delivery, along with finance and tax integrations. The service also supports recurring invoices, online payments, payment reminders, multi-currency invoicing, and a client portal. Core includes usage and hybrid billing, ingestion, alerting, invoicing, and integrations. Advanced adds data warehouse sync, Salesforce and NetSuite connections, customer hierarchy, and premium support. Enterprise adds enterprise-grade SLAs and dedicated support. Orb says pricing is based on billings and events, with a platform fee for Advanced and Enterprise tiers; exact prices are available on request. It has no free plan. Orb lists encryption at rest, TLS in transit, AWS infrastructure, virtual private clouds, and annual SOC 2 Type II audits.
