Nexternal is a modern hosted shopping cart, based upon ASP (Application service provider) model, meaning it is hosted, managed and supported on the hoster's servers. A unique pricing model is based on your monthly online sales. Charges varies from $250 to .5% of all sales per month. Distribution package is not available. This solution is equipped with a flexible shipping system and lots of features for product promotion and advertising.

The turn-off for this shopping cart solution is that you get software with a strictly fixed range of features which in itself is quite expensive. The software cannot be extended or customized at all since there is no module system, no access to the source code, free or commercial add-ons or even various packages with different sets of functions.
