Automate mixed-logic SaaS invoicing
The Problem
SaaS teams with complex billing rules exceeding ERP defaults still hand-build invoices from reports, creating bottlenecks as customer bases scale 10x-100x. The billing & invoicing software market is $7.4B in 2025, growing to $18.9B by 2034 at 10.9% CAGR, driven by automation needs for accuracy and efficiency. B2B SaaS market at $0.49T in 2026 expands to $1.58T by 2031 (26.24% CAGR), with 59% of vendors shifting to usage-based/hybrid models that amplify mixed-logic invoicing pains. Current spend: enterprises invest $10K-$50K+ annually on partial solutions, yet manual work persists.

Competitive Landscape
Custom enterprise pricing; starts at $25,000+ annually for mid-market based on volume and features (pricing not publicly listed, quote-based)
Zuora excels at enterprise-scale SaaS invoicing with usage-based and hybrid models but requires significant IT involvement for custom mixed-logic rules beyond standard subscription and usage, often piling work on teams for non-default billing scenarios.
Custom pricing; typically $10,000-$50,000+ per year depending on transactions and customization (contact sales)
Focuses on usage-based pricing for SaaS but lacks deep automation for mixed-logic rules that exceed ERP defaults, forcing teams to manually build complex invoices from reports for hybrid scenarios.
Usage-based: $0.25 per active customer per month + metered fees starting at $0.02 per invoice (free tier up to 100 customers)
Provides revenue automation for hybrid pricing but struggles with highly custom mixed-logic invoicing that goes beyond standard recurring and usage, leaving teams to hand-build from reports.
Custom AI-powered plans; enterprise starting at $20,000+ annually (contact for demo)
AI-powered for 95% billing automation but primarily enterprise-focused, missing affordable, flexible tools for mid-market teams handling ad-hoc mixed-logic rules outside ERP capabilities.
Freemium to enterprise; Pro plan $99/month per product, Enterprise custom
Redefines monetization infrastructure for scale but does not directly address invoice generation from reports with complex mixed-logic, acting more as a commerce layer than full invoicing automation.
