Hi Till, et All, Please be very clear on this. 1. Will ispconfig3 billing system have a template that will allow users to place orders similar to this? http://www.godaddy.com/hosting/web-hosting.aspx?ci=8971 or http://osc4.template-help.com/wt_30839/index.html 2. Or must an external Ordering Software (ad to cart, etc) first place the Orders as above. Thereafter Ispconfig3 admin finally implements the orders on the server thus generating invoices, etc ? thank you, peter
