Issue Summary

Our application requires a payment method by "invoice" or manual payment. This is supported by Stripe using the ACH credit transfer (see https://stripe.com/docs/subscriptions/ach-credit) however we do not charge in USD and also we are not located in the US so we cannot use ACH.

After some discussion with the support channel we found a way to implement this but it requires some features that are currently not supported by pinax-stripe.

I have implemented them in: Paul424@95145cd which is currently in "test" (i.e. not in production yet). Please do not expect a full/complete solution as this is just the part within the pinax-stripe layer, there are additional webhook implementations required for sending invoices, reminders and due-date handling, and most important you need some admin functions to set the invoice to paid/forgiven.

Would these changes be something you are interested in to merge into the master? Since there are some (small) model changes involved it would help a great deal... ;-)
