Hello Till & all. I know this issue was poped already from time2time; but I wish to know if ANYONE really took the chalange seriously; and is thinking about extending the basic invoice feature in ISPconfig to more detailed (but still simple) billing solution such as in: http://www.controlzx.com.:cool: This, for us, would make the decision as we hope version 3 will include it (BTW: When is the release version planned). Many thanks. Ori.
