I am just setting up as a webhost (mainly to ppl i know and the like) and am running a vps, but need some way to automaticaly take the customer details from the order and create the account in plesk, anyone know of a system that does that??

I think AWBS supports Plesk. You can try it.

Yeah i have looked at awbs before but at mo i cant afford the license untill i start either working or getting customers, does anyone know of any good opensource/gpl systems

phpCOIN is free and open source software. Also you can use an email form script at beginning.

AWBS is good
Try it
