Is there a way to show preview of orders before the payment as required by German law?

- will there be a 3 step payment check out (like in shops Overview etc) which is ok with the german law?

This is not done automatically for you, but it is easy to add to your forms by adding the following widget to your jotform: Preview Before Submit

As soon as you do, your submit button will be altered to first show the preview of the selections and only through it to allow the submission.

Once they are redirected to payment processor (like PayPal), they are also shown the amount to pay so this would be 3 step payment checkout, but if you feel that something is missing, or have issues setting it up do let us know.
