VP-ASP is open-source ASP-based software for online business. It is offered via several distribution packages varying in price and features (in our review we examine the features of the most powerful package).

In comparison with X-Cart, this software is much less cost-effective if we speak about license cost and support costs as well. It has limited upgrade period, more narrow range of services, extension add-ons and ready-made design schemas, less number of guaranteed solution options. Besides, this ecommerce product is based on ASP which is less flexible and easy to use in comparison with PHP which has much more open sourced documentation and hosting options.
