I have developed, a complete software product, consisting of a Joomla! Extension: VM Mass Update.
VM Mass Update is a complete solution for managing your VirtueMart products, no matter how many. It is designed specifically to come to the rescue of VirtueMart shop administrators that deal with a large number of products. Ever since the dawn of e-commerce, managing a large shop has been a very time-consuming task. For VirtueMart, not anymore.
