If you need to "buy" WinSCP, you can buy it from Microsoft Store:
https://winscp.net/eng/docs/microsoft_store

Though, I really do not understand this. Isn't it rather that you need to have support contract (which comes with the payment and the license)?

Because with license and payments come more responsibilities and bureaucracy. And that's something I want to avoid. I'm not even able to assess the risks to determine the price.

There's no misunderstanding, in the United states heathcare companies can not use freeware. Why you will not charge for a license is beyond me. Is there a similar product like this for purchase?

Sorry, we do not do that. What are those reasons? This looks like some misunderstanding.

My company can't use freeware for compliance reasons. Is there anyway to get a non free copy with a license agreement. The software works fine and has been validated.
