It depends on the type of file. Are they talking about paper files or digital files. I assume the first since you don't have any digital files. If you are talking digital, then it costs the same for one file as it does for 1,000.
$15,000 is way too much. This is where they get you. Once they get $15,000, they have made their money even if you never update or use their product.
FYI: Bert's opinion ahead: I would go with AC. But, given the fact that there are hundreds of EMRs, all overprices, but all which do great things if you want to pay for them, I am not sure why we are focusing so much on GloStream, other than your boss liked it.
I guess I am, well I know I am a control freak, but I simply don't know why the physician is not looking at these. No offense to you, but he/she will be the ultimate person using the program.
