ClientExec is a great billing and support application, that's designed to help with the management of small to medium-sized hosting firms. It's the connection between the front- and the back-end and it allows for some client to order a web hosting plan on the Internet then to have their account activated. ClientExec will make it a piece of cake for you to generate invoices, to put prices for hosting packages and domains or to see performance stats. Every time you use the application, you'll be able to include a payment processor, a domain registrar or an SSL supplier 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 web hosting business and other people to help you in this venture, you can give them different levels of access and each level will be able to access different sections and options in ClientExec.
