Stripe is a good option for developers, but they are very expensive. They lowered their prices two times this year in France (2.9%+30c -> 1.8%+25c -> 1.4%+25c),

Stripe is a good option for developers, but they are very expensive. They lowered their prices two times this year in France (2.9%+30c -> 1.8%+25c -> 1.4%+25c), but that's not enough to compete with local alternatives for medium to large businesses. It's very common to get "Interchange+" pricing in France, where the actual costs of processing are passed onto the merchant, plus a more transparent gateway fee (like a few cents). The fact they lack some critical features for cheap and reliable card payments (3DS, Carte Bancaire network + transparent pricing) is a no-no for more traditional businesses.
