Who it's for

AI and software startups that charge for usage (tokens, API calls, compute) rather than flat seats, and want billing infrastructure without building it in-house.

What you get

A billing platform that ingests usage events and turns them into invoices, supporting subscriptions, usage-based pricing, seats, credits, trials, and discounts, with Polar acting as merchant of record to handle worldwide tax collection and remittance and payment processing.

How it works

You wrap your product's usage events (e.g. LLM calls via an Ingestion SDK) or standard checkout flows with Polar's SDK and webhooks, and Polar meters the usage, generates charges, and manages payouts, refunds, and chargebacks automatically.
