I don't think the fees stack like that. The terminal page says 2.7% + $0.05 per transaction. I believe that Stripe Connect doesn't take an extra fee, at least not in my experience.

It does. It takes a percentage of the connected user’s sales AND a $2.00 monthly fee per user AND the normal transaction fee.

If there was a competitor to Connect, I would use it. Fees end up being around 3.4%. That’s pretty hard to sell customers on.

So 3.4% for card present? That will not fly except with the smallest of businesses. (which is not where the profit is).
