I seriously thought about it. One would have to set up and announce an 'Agency Policy' of sorts, and let that policy be known to all your insured's. In the end I decided it's just not worth the risk of losing/attracting and retaining customers. I'm not into giving anyone a reason to shop as the other Indy down the street that doesn't charge for certs. And in this day of social media and google reviews, slippery slope we work.
Now if it's brokerage business, nothing wrong with adding a set policy fee.
Brokerage as in surplus lines?
