Best alternatives to Orb in 2026
Charging customers a flat monthly fee is easy; charging them based on how much they actually use — API calls, tokens, seats that fluctuate mid-month — usually turns into a spreadsheet nightmare of custom invoicing code nobody wants to maintain. Orb exists so a team can define "here's how we charge for this" as a query instead of a pile of billing edge-case code, and get correct, auditable invoices out the other end. Orb is a usage-based billing platform aimed at SaaS and AI companies with complex pricing (seat-based, token-based, per-action, or hybrid). It captures usage events in real time, lets teams define pricing metrics with custom SQL, generates invoices with backdating support, and adds finance workflows on top — revenue recognition (ASC 606), accounts receivable, and dunning — plus CRM/ERP sync (Salesforce, NetSuite). The platform is built to process over 1 million billing events per second and is used by companies including Vercel, Replit and LaunchDarkly.
