ClientExec is a great billing and support app, which is intended to help the management of small to mid-sized hosting suppliers. It's the link between the front- and the back-end and it allows for a customer to purchase a web hosting plan on the net then to get their account activated. ClientExec will make it very easy for you to generate invoices, to set prices for hosting plans as well as domains or to watch performance statistics. Any time you use the software, you can add a payment processor, a domain name registrar or an SSL service provider with a couple of simple steps. ClientExec also contains a built-in ticketing system, that will allow you to provide support to your customers. If you decide to start your own reseller hosting business and other people to help you in this venture, you can provide them with individual levels of access and each level will be able to access different sections and options in ClientExec.
