What payment processing platform are you using for your business ?

I'm working for a client based in the netherlands, and we've been using a mish-mash of different payment processors. We're going to be selling all kinds of giftcards, and accepting a slew of different payment methods

The brunt of it is going through providers such as stripe:

PAYNL Adyen Mollie Buckaroo Xfers NeoSurf Aircash

If you need a recommendation for what to use, Hyperswitch has piqued my interest as you can connect it to stripe, it's open source and it's possible to host it on-prem

i'm likely going to be using stripe
