I would guess a few hours, definitely longer than it did with paper because I am doing more of the stuff that my staff used to do. For instance, I complete and fax back all the refill requests, I convert and name all the incoming faxes and put them in the appropriate "boxes" and I update AC when needed. My staff would have done these kinds of tasks previously. I log in from home most nights and finish waht I did not have time to do during the day. So there are some definite disadvantages.
