Last, but certainly not least are Affiliate management program solutions which are built right into your shopping cart.

As a Merchant just starting out, this may in fact be your best choice, because you won't have to wonder if the software you buy or lease will actually work with your third-party payment processor and shopping cart - it's built right in!

1ShoppingCart is the first choice among merchants who are looking for the 'full-meal deal' or all-in-one solution with all the tools you will ever need to do business online.

The short list of features includes a shopping cart that connects to your merchant account (with support for 60 different payment gateways, including Paypal) and does shipping calculations for your orders. Got a membership site? 1ShoppingCart comes with and Automated recurring billing system, or you can set up recurring billing for individual customers. You can track and split test your ads, and their service also comes with multiple autoresponders and an ebook delivery system.

1ShoppingCart is the system I have chosen to support my next non-digital project.
