Netherlands: online payment methods [betaalplatformen]

Netherlands: online payment methods [betaalplatformen]

Greetings!

I am located in the Netherlands, where I have several businesses. I am looking into online payment methods [betaalplatformen], mainly in order to be able to receive money on a "subscription basis" (i.e. every month money will be automatically paid to my account), but also for one time transfers (receiving) of (larger) sums.

- Stripe integrates with ZOHO and is now available & operational in the Netherlands, however they charge 1.4% of the amount (in addition to € 0,25 p/transaction) - this becomes expensive! I'd rather have a flat fee per transaction instead of a %. 
- iDeal seems a good platform, but -as far as I understand- not suitable for automatic periodic withdrawals (like subscriptions). Also, it doesn't directly integrate with ZOHO.
- Bunq ... well, I don't know.

There are several options in the Netherlands, and I am a little lost.

Has anyone (from the Netherlands) figured this out (best and least expensive platform)?

Thanks so much for your suggestions!
