Monetizing developer tools, digital downloads, and open source projects is bogged down by global sales tax compliance (Merchant of Record), recurring billing logic, and software license key management.
Polar serves as your complete Merchant of Record and monetization engine. Collect payments globally, handle EU VAT and US state sales tax automatically, provision digital license keys and file downloads, and reward open-source contributors with automated bounty payouts.
