Need subscription service for non-hosted software - cart, subscription management

Hi All

I’ve been looking around the past few weeks for some eCommerce software that suits my needs. It seems like there’s a lot of choice but you really need to dig around to get to the nitty gritty of what these eCommerce/cart apps do. Anyway I am looking for something and hoping to get some pointers off the members here.

I currently sell software and I am going to be bringing in a subscription based service in the next 3 months. Here’s what I am looking for:

  • Shopping cart where the customer can buy product and/or subscription at the same time
  • Subscriptions will be done via Paypal, subscription payments should be taken automatically until the customer cancels
  • Cancellations can be handled manually if necessary
  • The subscription is to a piece of software that installs on the customer PC, therefore I need an API to ‘phone home’ and see what the customer has access to

Any idea if there’s someone out there that fits my needs?
