If you already have a merchant account to process credit cards, find out what payment gateways are compatible with your account. From there, see which internet shopping carts work with the various payment gateways and then check the different features. Otherwise start by making a list of the features you want now (electronic delivery, coupons and quantity discounts, auto responders, types of credit cards, remote versus locally hosted depending on your programming skills, cross-selling features, and so on). Of course, if you are hosting the internet shopping cart on your own site, make sure your hosting company supports the database and language of the shopping cart software. See if your chosen vendor offers support, forums where you can communicate with other users of the software, and tips and best practices to help you get the most out of the shopping cart software.
