At a previous job the CEO/owner had the idea that you'd get some percentage of any cost saving your could find as a bonus. Something like 20% of the savings for the first year.

My colleague in the IT department had one idea, replace our commercial certificates with Let's Encrypt and drop the EV requirement. In total he'd stand to get a bonus of a little over €2000. He never got the money, because things like that was part of his job apparently.
