Interchange is the world’s leading open source e-commerce platform. It is a feature-rich development platform, which permits development on a number of levels. In addition to this, it comes bundled with a high-specification shopping cart template, which can easily be customised to suit your needs. In addition to these, Interchange offers an administration web interface for management of most aspects of your shopping cart or other web applications.

Interchange is one of the most powerful tools available to automate and database-enable your website or build online applications.

Interchange is well suited for a variety of purposes, including: sales, order processing, content management, customer service, reporting and analysis, and personalization. Interchange has been implemented for traditional retail sales, digital goods delivery, B2B parts re-ordering, non-commerce content management, auctions, order status checking, supply chain management, project management, online collaboration, and even an MP3 Jukebox.

Interchange can be used as a completely self-contained standalone product or as part of a larger system. It can be integrated with payment processing services, ERP systems, point-of-sale systems, accounting systems, external content management systems, Java-based application servers, sales force automation systems, customer relationship management systems, email campaign management systems, and remote databases on virtually any platform.

Interchange has an inline tag markup language, which is inserted into an HTML page.
Interchange has grown out of two earlier projects, MiniVend and Tallyman.
