It's in theory already possible with iDeal from what I can tell (I've seen companies that use subscriptions set up an initial iDeal payment and then convert it into a regular recurring SEPA Direct Debit), but I'm going to assume that the process is kind of messy since I haven't seen many companies implement the system in that way.

Direct Debit is very nice, largely because your bank manages the subscription; companies have to declare the payment ahead of time and if you get balance mixed up for some reason, then the bank will just do the payment whenever your balance is correct if it happens within a week. I've had credit cards decline on subscriptions before because I didn't have enough loaded up on them. Never had that issue with SEPA.

Either that or "credit cards just work", so very few entities bothered until now.
