yes he can later get a cpanel for the account. He just need to ask for this to his service provider and that will be added by the provider.

if you are hosting single website as a beginner then you may start exploring unmanaged VPS without control panel to host single website. it is also a good way to start building necessary skills... it will save you lots of money in the long run once you've mastered it as it will cut your dependence in control panel.

if it is just for single site use VPS or just hosting a few website which belongs to the same person, just run it without any panel, do it manually and save the RAM!

Yup..Install Kloxo on your servers. it is very simple.

it has all features like you can add reseller..s make packages etc.

its very efficient also. if you need help in install drop me a pm.

It depends if his upstream offers it. If not, you always have the option of purchasing an external license. Check out cPanelDirect.

Kloxo is good ,)

the answer to oringal question is. no.
you can install the panel later.

Our datacenter provide $10 for cpanel license but only allowed for internal usage.

Control panels licenses can be purchased externally to your hosting company, and installed by the user quite easily.

he can use a free control panel such as ispconfig

it is god option to save some money... but there are free panels like webmin and is good if you know how to use it..

I would always recommend cPanel OR Plesk control panel in a long run. Easy to manage things and install updates. There are license reseller like cPanelDirect which offer licenses at low price.

Unless a person has a need to get a VPS without a control panel such as proxies, etc they should always get a panel. It makes it much easier to run their box, unless they know how to effectively setup the services and processes without the panel.

you could install own kloxo free or if want cpanel its a cost which your provider can do

eventhough kloxo is the better free alternative, it seems to be having some security issues.
