Hey OL community! I want to introduce you Commet, The billing engine + MoR built for consumption-based SaaS:

The Problem: "Billing is a state machine nightmare". Most founders start with Stripe and quickly realize they’ve just inherited a second job: building a complex billing engine. Between webhook hell, handling usage-based credits for AI, and the legal nightmare of global VAT/Sales Tax, you spend 30% of your time on "plumbing" instead of your product.

If you use tools like Cursor or Claude Code, you know they struggle with billing because the logic is usually decoupled from the payment gateway.

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.

How it works:

1. You define your pricing: Credits, subscriptions, or hybrid models.

2. We handle the logic: No more manual webhook syncing. Your app just asks our API: "Can this user run this AI task?" and gets a real-time boolean.

3. We handle the taxes: We are the legal seller, so we deal with the compliance, invoices, and global taxes.
   

Key Features:

• Built for AI/Usage: Perfect for credit-based models where margins matter.

• Deterministic State: Forget about race conditions or revenue leakage.

• MoR Model: We take the tax liability off your shoulders from day one.

• Developer-First DX: An API designed by devs who were tired of reading 50 pages of Stripe docs just to add a "pro" plan.

The "Why" behind Commet: We built this because I was tired of building the same billing engine for every SaaS I launched. Billing shouldn't be a hurdle; it should be a simple permission check.

I’d love to hear your thoughts! Check out our logic in action (no account needed) at sandbox.commet.co. I’ll be here all day to answer technical questions!
