Stripe: General-purpose payments processor with flexible billing options
Polar
Billing and revenue platform for AI and infrastructure companies
As of 29 August 2026, Polar has a free plan and paid plans start at $20/month. Polar is a comprehensive billing platform designed for AI and infrastructure companies that need to monetize usage-based services. Softwr lists it under Accounting. Polar is available on Web, API.
Overview
What Polar does
Polar is a financial infrastructure platform built specifically for the intelligence era, enabling AI and infrastructure companies to monetize their services with a single API integration. The platform handles all aspects of revenue operations including usage-based billing that meters tokens, API calls, compute, and storage at the event level; subscription management with built-in trials, upgrades, and proration; seat-based billing with automatic add/remove functionality; and prepaid credit systems that deplete as customers consume services. Unlike traditional billing platforms, Polar acts as a merchant of record, assuming legal responsibility for payment processing, sales tax collection, and compliance across 100+ markets. This eliminates the complexity of managing multi-jurisdictional taxation and payment infrastructure. A key differentiator is Polar's ability to reveal true unit economics by collecting every payment, enabling companies to see gross margin calculations per customer and identify unprofitable accounts. The platform offers a flexible pricing structure ranging from a free Starter tier to specialized plans, including a Startup Program that provides the Scale plan free for 12 months to early-stage AI companies.

- Percentage-based fees higher than some specialized processors for high-volume transactions
- Merchant of record model may not suit companies preferring direct payment control
- Free Starter tier limited with 5% fees reducing appeal for production use
- Setup and integration effort required despite API simplicity
