We use MultiSafePay, which is a "online checkout" solution (you're routed to their site with your template if you have the most expensive plan). They support credit cards, but that's based on acceptance by their processor, PaySquare. The problem boils down to, just like Canada mentioned above, there are only two or three credit card processors. Even Ogone uses PaySquare or Atos Worldline in the Netherlands (they, like FeeFighters have different relationships in different countries). Ogone is a spinoff of Fortis bank, so is quite "bank minded".

I meant iDeal, which will allow you to reach most Dutch internet users, as opposed to PayPal or credit cards (relatively few Dutch people have credit cards).
