About

ChaChing is a Stripe Billing alternative that cuts SaaS subscription billing fees by 50%. At 0.35% of billing volume (vs Stripe Billing's 0.70%), SaaS companies save thousands annually without changing their payment processor. Stripe still processes every payment. ChaChing replaces only the billing management layer — subscriptions, invoicing, dunning, tax compliance, and analytics. Built on Kill Bill, the open-source enterprise billing engine (Apache 2.0) trusted by Fortune 500 companies invoicing billions annually since 2010. Kill Bill's core engineers are actively involved in ChaChing's development. Key features: - 0.35% billing fee (half of Stripe Billing) - Automated subscription management with smart dunning - One-off and recurring invoicing with payment links - Native TaxJar and Anara tax integrations (Avalara coming soon) - Real-time MRR, ARR, LTV, and churn analytics - REST API with OpenAPI spec and testing sandbox - Branded host

About

Solvimon is billing infrastructure for software and AI companies. One system for metering, pricing, quoting, invoicing, payments, and revenue recognition. You send usage events (tokens, API calls, agent actions), Solvimon meters them, applies your pricing model, and generates the invoice. Any model works: seats, usage, prepaid credits, volume commits with overages, outcome-based, or any combination on one contract. Mid-cycle changes, credit rollovers, and multi-year ramps run without custom code. Payments are PSP-agnostic (Stripe, Adyen, Checkout.com) with multi-currency settlement and built-in tax, VAT, and GST. Bi-directional integrations sync your CRM, ERP, and data warehouse. Developers get a full API, SDKs, a CLI, and an MCP server so AI agents can operate billing directly. Built by the team that ran billing at €1T+ volume at Adyen. Used by AI-native startups and large enterprises on the same platform. No event limits on any plan.
