Hello, and welcome.
If your boss travels both internationally and domestically, Global Entry (GOES) is the best choice, because it it more economical and also includes TSA Pre. The fee is $100.
If your boss travels only domestically, then a GOES card is not needed and an application, then appointment at an enrollment center for TSA Pre, would be the better choice, at $85.
As you can see, even if there is a chance he will travel out of the country, getting a GOES card is much more worth it, since it includes the TSA Pre for only $15 additional.

I hope this helps.
