Want to keep track of sales so that you'll know when to reorder products? How about limiting sales so that you don't oversell a limited-edition product or one that you don't want to reorder?

Shopsite's inventory tracking module can do that for you, and you can even set Shopsite up to send you an e-mail when stock of a product is low or out. It also can be setup from within the Shopsite backoffice to prevent customers from ordering a product that is out of stock.
