Payware Payware is, as a matter of fact, all software in your shop. It means: first you pay, then you get to know what your program is exactly able to do. Sometimes Payware is called commercial software, but properly spoken all software you have to pay for is commercial. The one and only difference between Payware and Shareware is that Payware has to be payed in advance and that Shareware can be tried out first; you only pay if you want to continue the use of it.
