Techincally our software is free/donationware for personal use, but we welcome business customers, and we are happy to issue site-wide business licenses.
For site-wide business licenses, I generally ask for $25, plus $1 to $2 per computer that would be using the program, depending on the number of licenses (figure anything < 100 users would be $2 per license).
(You dont need each user to enter their own license code, a simply file in the program directory will make the program and any future versions licensed forever. We can provide a custom installer for large orders).
We are happy to provide some special support for business licensees, and are happy to discuss adding custom features, etc. and provide a formal contract.
Feel free to email me to discuss further: [email protected]
