licensing user owned sftware on co PC

I am working helpdesk at a company that provides it’s independent contractor sales agents with a computer. Sometimes these sales people want to install their own software, such as ACT, Goldmine, ect..

Aside from having them bring in their valid software license before being permitted to install, should the company be taking any more steps to ensure that it’s computers are in compliance with software licensing.

For instance, should the company keep the user’s software license for it’s own records? Any info or links to licensing resources would be appreciated. Thanks.
