Hi all, A question came up the other day regarding charges in core facilities. Namely, whether it is appropriate to charge users for time that they booked v. time actually using in instrument. So, for example, a user books 2 hours on a microscope, but logs into the system 15 minutes late (we are using Stratocore and have the real-time usage tracker active), the person left 8 minutes early. So, in that case would the user be charge for the full 2 hours, or would we need to bill for the 97 minutes actually used? I am a little unclear on this, as the scope is unavailable for the full time booked, and the user could have been prepping samples before logging into the system. Our sponsored projects person believes that we should only charge for the time that the microscope is active, but I see it as the user has the instrument for their allotted time and should be billed. Thus, I was hoping to see how others handle this situation. Any advice would be greatly appreciated.
