Paddle is a payments and billing platform built for software and SaaS companies that acts as a merchant of record, handling checkout, subscriptions, sales tax, and compliance so businesses can sell globally without the operational burden. Selling software internationally involves payment processing, fraud prevention, subscription management, invoicing, and a maze of tax obligations across countries — a lot for any company, and overwhelming for smaller ones. Paddle consolidates all of this into a single platform and takes on the role of seller of record, dramatically simplifying the business side of selling software.

As a complete billing solution, Paddle handles the entire payment lifecycle: a checkout that converts across regions and currencies, subscription and recurring billing management, invoicing, dunning for failed payments, refunds, and detailed revenue analytics. Because it's the merchant of record, Paddle is legally responsible for collecting and remitting sales tax and VAT worldwide, removing one of the biggest headaches of international software sales. It also provides fraud protection and the infrastructure to manage pricing, plans, and the financial operations behind a SaaS business, all through one integration rather than many.

Paddle is used by SaaS companies and software businesses — from growing startups to established firms — that want to outsource the complexity of payments, billing, and tax compliance. The value is focus and simplicity: instead of building and maintaining billing infrastructure and worrying about global tax law, companies get a single platform that handles it all and lets them concentrate on their product and customers. By taking on merchant-of-record responsibilities, Paddle gives software businesses the ability to sell worldwide with confidence and compliance. For SaaS teams that want billing and tax handled end to end, Paddle is a trusted, comprehensive solution.
