ClientExec is a great billing and support app, that's intended to help with the control over small to medium-sized web hosting providers. It is the connection between the front- and the back-end and it allows for some client to get a web hosting plan on the net and to get their account activated. ClientExec will make it extremely easy for you to generate invoices, to put prices for web hosting packages as well as domain names or to see performance statistics. If you use the app, you can add a payment processor, a domain name registrar or an SSL provider with a couple of easy steps. ClientExec also features an integrated ticketing system, which will help you 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 provide them with separate levels of access and each level will be able to access different sections and options in ClientExec.
