Dropshipping financial setup

I am struggling with setting up my financial funnel.
I set up shopify accounts in the US.
I am anItalian citezen residing in Egypt & constantly travel around (mostly Spain & Turkey).
I am struggling to connect my shopify accounts to my Revolut or Bunq accounts which I use.

What can be the best setup considering I am residing in Egypt to avoid taxation in Europe.

Tried setting up paypal which works but I doubt it will be accepted by Revolut.
Tried setting up N26 - Mercury - Wise
