SalesCart STD maintains the LinkWise™ CheckOut system first introduced with SalesCart 1.0. The LinkWise CheckOut system divides the checkout process into logical steps and gives SalesCart incredible customization power.

Unlike most checkout systems, which involve only a single step, the LinkWise CheckOut system is more easily customizable to calculate sales tax and shipping costs on the fly. It can also be changed to remove checkout steps. For example, if you sell services instead of tangible products, or want to deliver products directly on the Internet, the web site designer can easily remove the calculation of shipping charges, often without the use of a programmer. Or you may wish to produce a shopping cart system to distribute brochures, literature or other forms of data which may be free. Using LinkWise, it is easy to remove the entire payment step from the checkout phase. The LinkWise CheckOut system makes SalesCart STD one of the most easily customizable shopping cart systems available. Other shopping cart systems providing this level of customizability require the services of a programmer or a highly skilled scripter to make similar modifications.
