Sell ​​software online with a third party

Duplicate https://stackoverflow.com/questions/409026/software-marketplace

I am interested in selling software (mainly enterprise libraries) on the internet, but I am not interested in handling money / shopping cart / etc, so I am on the lookout for a third party that can handle all my payments / downloads for a fee (a bit like Google Ads, but for software instead of ads).

The ideal scenario would be that I just need to upload a file to their server, set a price for each file, and link to an address from my own site.

Anyone have any experience with these things? Any vendor you can recommend?
