Magento is an open source application for webshops, which recently has increased greatly in popularity. In Magento all failures of other shop applications (such as osCommerce, VirtueMart and Zen-Cart) are resolved.
Magento has included support for multiple shops (with the same or some other products) and multiple languages. In addition, you can use Magento to generate various marketing reports.
Magento offers various ready-made solutions for payments and shipping methods. You can integrate UPS Tracking with a few clicks and you can just as easily install PayPal or iDEAL. It also allows you to quickly and easily install other payment and shipping methods.
The builders of Magento also thought about search engine optimization, management tools and so on.
In short, Magento is ready for your future!
