ClientExec is a great billing and support app, which is made to facilitate the control over small to mid-sized web hosting suppliers. It's the connection between the front- and the back-end and it allows for some client to acquire a hosting plan online and to have their account activated. ClientExec will make it extremely easy for you to generate invoices, to put prices for hosting plans and domains or to check out performance stats. If you use the app, you'll be able to add a payment processor, a domain name registrar or an SSL supplier in several easy 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.
