Licensing my program

Hi, i’m developing a Point Of Sale software and would like to find out possible solutions to manage licensing my program. I have tried a couple of tutorials from YouTube but found little free solutions to my problem. I would like to emphasise that there are two programs i offer: POS and BackOffice. Licensing every POS machine would be problematic (if somebody had 20 registers or so) so i thought that licensing only back office software (which is usually on one pc) would be enough. What do u think?
