Hello,
I am in the middle of programming a very powerful and clean billing software, it will be integrated with Ensim, it will support multiple machines etc.. I want to know if anyone is interested in it? I am not sure if i am going to release it but if there is a demand i will license it for a fee... If anyone is interested PM me and maybe i will show you what is done so far, i may even give out a few free licenses for beta testing..
