Maybe have a chat to Drew Wilson who is working on http://spacebox.io. It's a nifty little tool for collecting payments via Stripe.
I believe he's currently working on adding subscription payments (and hopefully invoicing) which I am very keen to get but affiliates/electronic delivery could be another great add-on for him to deliver.
