Hi,

I created a client which is communicating with web servise and that web service is further communicating with tax administration and returning me the number for  invoice (fiscalization). From other side I would like to have a button after I validate the invoice which should send needed data from the invoice. My question is is it possible to do it somehow on the accounting module, or I have to inherit the whole accounting modul and then do it there? 2. question, if I inherit it will I loose all upcoming upgrades, since it is no longer standar accounting module?

Thanks in advance

Bruno
