Product & Service Introduction:
===============================
Whois.Cart() is a client/administrator tool that facilitates the many tasks involved in running an efficient
webhosting and domain registration business. The system will surgically undertake every aspect of your client
transactions; first the sale (which is most important and most overlooked), the collection of money, the
registration/transfer/renewal of domains, the provisioning of hosting space, and lastly the maintenance of all
these. A cumulation of countless development hours and thousands of user suggestions, Whois.Cart() is a
full-featured system that has retained the clean and simple ethic that most of its equal-featured competing
products have lost. It will undoubtedly become the most natural and effective resource with which you will
ever complement your business.
