Muddawg,
My .02 would be (and this is informed .02 having had this discussion with several different state/fed wildlife managers not long ago) is
that most of these folks don't understand how/what you do as a bat excluder.
They don't understand that the goal is to move the bats from the structure and if you don't need to touch them or count them to do that
than that is perfect.
I actually fielded a question at a conference recently related to this where I was asked if the average excluder knew how to i.d. bats.
My response is something I've discussed with others including Eric and relates to our need or lack of need to i.d. bats, what it involves
if they desired us to do so as a state/fed agency, etc...
This would be something that upon receiving it I would want to be discussing within my peer group in my state or my national association to address this coming down from a legal authority such as your NC wildlife agency.
If they desire that info, they should be providing the training they would like to see (the state) and furthermore they need to understand that while bat watches can be done and are done by some where possible or needed, they aren't the norm as most folks have to keep moving and identify the locations for one ways and so forth and move on to the next one.

If this is a new request and they are pushing it, it is very likely related to WNS (white-nose syndrome) and they are hoping to gather extra information from those who are seeing more bats than anyone else, the NWCO's.
***
Now don't get me wrong, this is a great opportunity to interact and work collaboratively with your state wildlife agency, but they should be gathering up a training seminar or meeting to visit with you folks in the industry and making sure you can all voice how you do this work, why certain aspects aren't necessary and would cost you money time and handling individual animals (something with inherent risk to you and the bats) and so forth.
***
Okay, more like a nickel than .02 but you see where I'm going, I'd be talking to my colleagues and forming a group if you aren't associated with NWCOA or a state NWCO group and going to visit these folks to have a good and productive meeting.
I had no qualms or fights from 6 states and other interested parties at a conference in Boise a couple of months back about why we don't need to know every bat to exclude them, and why we generally don't handle them unless you are talking a bat loose in the house (living space).
***
Again, it was folks not understanding what we do, ignorance is not malice, but unfortunately can breed anger between folks.
***
Reach out, and get someone on the horn and see about creating a great working relationship that might generate leads for you as well
as a guy who desires to help but needs to explain constraints!
