I have phpmyadmin, but I was hoping for ready solution(module). Unfortuattly person that is responsible for sales, products, stoc etc. don't know anything about databases, so as I was afraid it won't be possible for him to do it as new products will be added.
Anyway, thank you for your help, if I ever do everything I want to do in the shop I'll try to find some time and maybe write module for this
