I've written a php script that I'd like to take a stab at selling. I've spent a good amount of time looking for software to setup a storefront, but can't seem to find anything that does what I want: take payments (paypal, and possibly others like amazon pay). handle licensing allow multiple software products cost less than $200 I'm not interested in answers like woocommerce, or magneto - I want software that will generate a license key, and allow me to remotely disable software installs. Anyone point me in the right direction?
