Submit checkout not displaying

Everything up untill the checkout page works just fine, but after the user enters their payment gateway info there is no button to complete the checkout process.
I reviewed the checkout workflow and removed the shipping method. Can someone tell me what the issue might me.

Hi,

I can see the next button to submit the cart info on your checkout.

Hmm that is weird, I do not see it.

You didn't register yet.

Ohhh I though I configured the option to I user can do a guest checkout, but I also get an error after clicking the next button.

Also is this the correct checkout workflow, I want the user to able to submit the payment right after registering

1. It is indeed a guest checkout as no user account is created. The text of the button is "register" but you can change it to "proceed" if you want with a translation override:

What error do you have after clicking the next button ?

2. In that case you should also put the T&C view on the first step of the checkout.
