Open source (free) commerce for enterprise
Extreme value for (no) money
Drupal Commerce is without doubt the most sophisticated eCommerce platform we know of that is (truly) open source. Pair that with the fact that it's built on Drupal, it is an extremely powerful way to do an awful lot with eCommerce. We work on a number of Drupal Commerce websites, and whilst no high end build is without its challenges, we've achieved an awful lot for our clients on the back of Drupal Commerce's success.
