Solvimon
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.
