How one developer unified billing across multiple products using a single Paddle account

A developer who builds multiple small web products — including browser extensions and SaaS tools — found the repeated billing setup for each product time-consuming and frustrating. After studying Paddle's architecture, they discovered that the platform's approved-domain restriction only applies to the browser-based checkout overlay, not to server-side operations like webhook handling or API calls. This insight allowed them to consolidate all billing under one Paddle account, one approved apex domain, and a single webhook endpoint that routes incoming payment events to the appropriate sub-product. The central dispatcher verifies webhook signatures and forwards raw events without needing any knowledge of individual product logic, keeping it simple and maintainable. Satellites hand off checkout flows to the apex domain via short-lived signed tokens, ensuring users always pay on an approved domain without a disruptive experience.
