Commerce. Drupal Commerce is used to build eCommerce websites and applications of all sizes. At its core it is lean and mean, enforcing strict development standards and leveraging the greatest features of Drupal 7 and major modules like Views and Rules for maximum flexibility. Whereas eCommerce solutions are often developed with an application mindset, highlighting what you can do with it out of the box, Drupal Commerce was developed with a framework mindset, focusing on what you can build with it. The core Commerce systems make no hard-coded assumptions about your business model, privileging developers and site builders at the core level to build custom eCommerce solutions to suit.
