Remote access

First thing to do is find if Quickbooks has a remote access option. You may not need another program, just either a direct connection or internet connection. If you do it this way you definitely need Quickbooks installed on your pc. I am not sure how other programs work but GoToMyPC and LogMeIn are the best that I know of and they may connect direct so you don't need to have Quickbooks installed. Even just finding a way to upload and download the file so you are working on a local file that you can trasfer when you are finished. That way especially you have a back up that you can use to check and correct mistakes rather then work on the only copy that can be messed up. The owner of one place I worked at did that. He did the work at home and just transferred the finished files.
