Hi, Let's divide this up so that it is more comprehensible.
1st: you want to define products (in OFBiz terminology) that can be ordered/requested/subscribed to by users - this functionality is in place. 2nd: you want to invoice these users for the service rendered - this functionality is in place 3nd: you want to retrieve payment for the service rendered - functionality for integration with several payment processing providers is in place. 4th: you want to do other things - this is to vague.
