Hi Hansjörg, We are the developper for igestis, and we just release today a new module to make commercial invoices. Unfortunately, you cannot generate invoice from calendar for the moment, but it's probably possible to make a script to do that automatically.
I let you have a look on our commercial module on http://www.igestis.org/installer-commercial-pour-igestis/ (sorry page is in french, but we are currently translating the website). You can also have a demo on http://demo.igestis.org If you have a budget to do that, we could also make you an offer to make the script for you. Thanks.
