Drupal Commerce is a professional e-commerce solution for Drupal 7 and beyond. The core modules are lean and mean, enforcing strict development standards, a hard separation of underlying APIs from the default UI, code comments and documentation, and full test coverage.
Core features like Products and Orders take full advantage of D7’s core Entity and Field systems. The modules leverage the popular Views and Rules modules to provide easily customizable user interfaces and order workflow automation.
