ClientExec is a great billing and support app, that's intended to help the management of small to mid-sized website hosting companies. It's the connection between the front- and the back-end and it allows for a client to get a web hosting package on the Internet and then to get their account activated. ClientExec will make it super easy for you to generate invoices, to put prices for website hosting packages as well as domains or to check out performance stats. Any time you use the app, you'll be able to include a payment processor, a domain name registrar or an SSL supplier in just a few simple actions. ClientExec also features an integrated ticketing system, which will allow 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 give them separate levels of access and each level will be able to access different sections and options in ClientExec.
