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.

flatpass puts a price on Discord roles. Connect a Stripe account, pick a role, set a price. Buyers arrive on a branded invite page at your own vanity URL. A tier can bill monthly, quarterly, every six months or yearly, and members pick at checkout. Charges are Stripe Connect direct charges against the seller's own account. The seller is merchant of record, payouts follow Stripe's normal schedule, and flatpass is never in the money path. Authorization happens through Stripe Connect, so no API key changes hands. Billing is a flat monthly fee rather than a share of revenue. The first 15 paid members cost nothing and plans start at $29/month. One account covers every server an owner runs, with paid members pooled across all of them. Stripe handles renewals and failed payments. When a card fails the role stays active while Stripe retries it and the member gets a link to update it, so nobody is lost to an expired card unnoticed. Free trials and discount codes are both supported at checkout. Already selling access elsewhere? Run flatpass alongside what you have and move members over as they renew. The free tier covers the first 15 paid members, so the transition costs nothing. Every invite link accepts an optional ref tag, breaking visits, joins and conversion rate down by source.
