Description

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.

Description

Stax Bill offers a blend of automated subscription management and personalized payment solutions. Our service allows you to streamline repetitive tasks, freeing your time to concentrate on overarching goals. Enhance your operational efficiency, boost your revenue recovery, and increase your invoice collections. Experience up to an 80% reduction in time spent on monthly billing tasks, and mitigate late or failed payments by as much as 700% through our credit card retry functionalities. With our automated collection features, businesses can recover an additional 2% to 4% of their monthly revenue. Imagine the extra hours you could reclaim if your billing system autonomously generated customer invoices. Many companies report saving as much as 40 hours each month by leveraging automated accounts receivable processes, which can be a game-changer for productivity. 🤯 Need to swiftly introduce a new item to your product range? It's a breeze. Want to conduct a minor pricing test? Absolutely doable. If sales teams request a subscription price adjustment for a specific client, feel empowered to accommodate their needs—the customer is always prioritized. With Stax Bill, flexibility and efficiency go hand in hand.
