Drupal Commerce is used to build e-commerce 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 e-commerce 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 e-commerce solutions to suit.
