File Transfer Confirmation

I use WinSCP to upload files from our server to our outsourced billing office. I am wondering if there is some sort of file transfer notification report that can be utilized as an audit trail for what has been transferred. Or, can I get a notification alert when files have been transferred? My current audit trail is just doing a print screen of what I have transferred each day, and saving it on our drive. Please advise...

WinSCP supports various forms of logging, if that's what you ask for:

When I submit a file (drag and drop a file from my server to the outbox), I am looking for a confirmation that shows my file has, indeed, been received by the other party. Is any sort of report or confirmation available for this?
