I have customers set up in our credit card processor that automatically pay their monthly or quarterly bill. They currently do not have invoicing set up in Odoo (I presume I need to do that first) but once they do, can I set up Odoo for automatic recurring payments as well as invoices? 

I understand there must be an invoice (subscription) to start with. I don't know how to connect that invoice with automatic payment in Odoo. Does it stay set up in my credit card processor and I just match them in reconciliation or can it be automatically matched? How to set that up?
