ClientExec is a great billing and support app, that's designed to help the control over small and mid-sized website hosting companies. It's the link between the front- and the back-end and it allows for some client to acquire a website hosting plan on the Internet and then to have their account activated. ClientExec will make it really easy for you to generate invoices, to put prices for hosting packages as well as domain names or to watch performance stats. Any time you use the app, you can include a payment processor, a domain name registrar or an SSL supplier with a couple of simple actions. ClientExec also includes an inbuilt ticketing system, which will enable you to provide support to your customers. If you decide to start your own reseller website hosting business and other people to help you in this venture, you can provide them with separate levels of access and each level will be able to access different sections and options in ClientExec.
