I work on a couple of products which are both low-volume desktop software licensed to engineering businesses and city departments.
Both products currently use licensing systems that are somewhat inconvenient, and not integrated with our sales website. I'd like to have something like a turnkey website and subscription-sales system (with an API, so that our software can hit it) intended for this purpose. I would like a package that includes basically everything: design templates, shopping carts, account system for users, payment gateway, license subscription auto-billing, and an API for integration into our software.
Does anyone know of anything like this?
