I m currently trying to integrate stripe subscription api, for my soon to be launched service. Could you tell me why I should consider you instead of them?

As pointed out by dan_bk we provide a bunch of features above the plan based subscriptions Stripe offer.

If you think you are going to be selling your product with usage based pricing, or want to use tiered pricing then we can add value from what you get with Stripe. Feel free to drop me an e-mail at ian AT billforward . net and can talk through you use-case.

It could be valuable to have a feature grid kind of page where you compare your platform to the built-in subscriptions in Braintree and Stripe, to provide an explicit list of the things you can handle that they can't.

Yeah, for example, see MailChimp's feature table for their Mandrill service that allows prospective customers to compare Mandrill to SendGrid (the market leader?):

I definitely prefer pages like that.
