ClientExec is a great billing and support app, that is designed to help with the control over small to mid-sized website hosting providers. It's the connection between the front- and the back-end and it allows for a client to order a hosting package on the Internet and then to get their account activated. ClientExec will make it really easy for you to generate invoices, to put prices for web hosting packages and domains or to see performance stats. Every time you use the app, you can add a payment processor, a domain registrar or an SSL service provider with a couple of simple actions. ClientExec also includes a built-in ticketing system, which 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 individual levels of access and each level will be able to access different sections and options in ClientExec.
