Delivered Sales - Has it been downloaded?

[phpscripts]

I’m in the business of selling PHP scripts that I have written. As such, most of my work is very easy to deliver. I have a .zip file that I send to the Buyer, and just like that I’m done my job. However, if somebody doesn’t complete the order for a day or so, I find myself wondering if they’ve taken my work and are planning on cancelling the order (to scam me out of money).



I wish there were some sort of Log that I, as the Sller, were able to access which would let me know if the Buyer had downloaded the .zip file that I Delivered.



Just a suggestion…



Thanks
