I am in the process of looking for a new platform for my huge customer base and its such a shame to see such a powerful software not support such a simple feature. I see you are allowed to sell digital products but can only send a download file. My products require me to send a download file and needs to be able to use a license key to activate the product, therefore each customer should receive a different license key pulled from a database of license keys and that key shall be deleted after being handed out. If you support such a feature you would surely have more customers yourself on your platform, the digital market is huge.
