I have a business account and my settings are already set for clients to pay with credit card when they don't have an account. But there is no way this is possible. I created an invoice and also a pay button, and nothing. It always request my client to register with paypal not showing the option to pay with credit card. This is is really unnerving and I need that payment urgently. Do I have to set up something else? I'm in Germany, client is in the USA, my invoice is in USD.
