Best Recurring Billing Software for SendGrid

Solvimon replaces home-built billing code. It is one API-first system for usage metering, pricing, quote-to-cash, invoicing, payments, and revenue recognition. Send raw events (tokens, API calls, agent actions) via API or ingest them from Snowflake, BigQuery, Redshift, S3, GCS, or Azure Blob Storage. Solvimon aggregates them against meters, prices them with whatever model you sell (seats, usage, credits, commits with overages, outcome-based, or all of it on one contract), and produces the invoice. Payments run through Stripe, Adyen, or Checkout.com, so no PSP lock-in. Tooling: REST API, SDKs, frontend components, a CLI, and an MCP server for agent-driven billing operations. Sandbox available without a sales call. The team previously built billing at Adyen (€1T+ processed volume). Pricing changes ship as configuration, not as a rewrite of your invoicing pipeline.
