Not sure about OP, but if you're looking to run a EU SaaS company for B2C or B2B, then I can highly recommend Xolo(https://xolo.io). They handle all the heavy lifting from a tax perspective.

They help you get your company set up (with e-residence) and then hook into either Transferwise or LHV for banking (and stripe, etc flows into that).

Very friendly as well, I'm in Estonia currently and I dropped into their office yesterday to say hi.
