(Pm on Stripe billing) There's a param in the API that indicates whether you want an invoice to be sent out or charged automatically -- you want `billing` to be `send_invoice`: https://stripe.com/docs/api#invoice_object-billing
For receipts, you can turn them on in your account settings: dashboard.stripe.com/account
> Under invoices there are two new documents "Invoice PDF" and "Receipt PDF" which are different from the standard e-mail receipts. Are these documents emailed to the customer automatically? Is there a way to control this?
