Payage Pro is a Joomla payment management system designed to simplify the integration of eCommerce applications with multiple payment gateways. Fully maintained for Joomla 5 and Joomla 6, Payage provides an independent payment layer between your application and payment providers, helping developers build cleaner, more flexible, and easier-to-maintain payment integrations. Payage is not a shopping cart or booking system. Instead, it handles the payment integration layer, allowing multiple Joomla extensions and applications to use a common payment infrastructure without implementing separate gateway logic for every application.
