Billing and invoicing

One billing engine, every interface

Your engineering team integrates through our SDKs or the full API. Your business team can operate Commet through the dashboard or MCP, alongside your own agents.

Pricing that fits your product

Usage-based, token-based, free tiers, and trials. Model your pricing around your product — not your billing tool.

Dunning that recovers, not annoys

Customize timing, channels, messaging, and save offers to recover failed payments before they become churn.

Model any plan

One plan, any billing model

Build plans around usage, credits, or prepaid balances. Measure and bill every event without hacking your product.

Overage on autopilot

Set and update limits. Commet tracks consumption in real time, applies overage billing automatically, and handles proration when users switch plans.

Coupons and custom offers, zero edge cases

Give sales and growth the tools to launch promo codes, flash sales, and introductory offers, create save offers and win-back promotions, and set custom pricing for specific customers.

Payment agnostic by design

Connect every PSP you need

Plug in Stripe, dLocal, Rebill, and more through one integration. Add providers as you grow without touching your billing logic.

Orchestrate with your rules

Route each transaction to the right PSP based on country, subscription type, or any rule your business needs. Tokenized cards let you switch PSPs without rebuilding your payment stack.

Never lose a payment again

Smart retries adapt to every decline: the right provider, timing, and rail. Turn failed charges into recovered revenue, not lost customers.
