About Polar Sh
What is Polar Sh?
Polar Sh is a billing platform designed for AI-native companies. It combines usage metering, subscription management, and invoicing into a single API, acting as a merchant of record. It helps SaaS and AI startups automate billing for tokens, API calls, compute, and storage.
Problem it solves
Manually tracking usage and billing is error-prone and time-consuming. Polar Sh automates the entire billing cycle, from metering events to generating invoices and collecting payments. It also provides real-time cost insights, so you know your true gross margin per customer.
Who it is for
Ideal for AI startups and infrastructure companies that need to bill for usage-based services. It is not suited for simple flat-rate subscriptions without usage tracking.
Use cases
Meter token usage for LLM APIs, charge per API call, manage seat-based pricing with automatic proration, sell credits, and handle global sales tax and payouts.

- Usage metering — Track tokens, API calls, compute, and storage in real time.
- Subscriptions — Manage recurring plans with trials, upgrades, and proration.
- Seats — Automatically add/remove seats and prorate charges.

- Merchant of record — Polar handles payments, sales tax, fraud, and chargebacks in over 100 markets.
- Payouts — Settle revenue to your bank account on your schedule.
