Commet

Billing and payments made easy for global startups

Visit

The Problem: Let’s be real, building a billing system is a "state machine" nightmare. Between webhook race conditions, handling AI credit burn, and the absolute headache of Global VAT/Sales Tax, you end up spending 30% of your time on plumbing instead of your product.


The Solution: Commet, we built Commet to be the "Source of Truth" for your SaaS. We aren't just a payment layer; we are a Merchant of Record (MoR) with a deterministic billing engine inside.

Features

  • Deterministic Logic: No more manual credit syncing. Your app asks our API: "Can this user run this task?" and gets a real-time boolean.


  • Global Tax on Autopilot: We are the legal seller. We deal with the compliance, invoices, and tax nexus so you don't have to.


  • Built for 2026 Startups: Perfect for credit-based, usage-based, or hybrid models.


  • LLM-Ready: Our logic is so clean that even your AI coding agents won't mess up the integration.

Use Cases

  1. AI Tools with Credit-Based Pricing: You built an AI image generator and want to charge per generation without building complex billing logic.
  2. SaaS with Usage-Based Pricing: You're building a dev tool API and want to charge for API calls with overage pricing.
  3. B2B SaaS with Seat-Based Pricing: You have a team collaboration tool and need to charge per team member with self-service upgrades.
  4. Indie Hacker Wanting Fast Monetization: You built a side project and want to start charging without spending weeks on billing infrastructure.
