How to have products section without integrating payment method?

Hi I don't want to integrate any payment method in my order form. How do I do that while having the products section pictured below?

You can switch payment processor of your form to Purchase Order. It does not process a real payment, but only collects orders. This should help to keep all products shown on your screenshot. 

In order to change payment processor on a form, please delete payment field. Other payment integrations would become active, please choose Purchase Order and add it to your form. Settings and products should be transferred to new payment field automatically. 

We will be glad to assist if you need more help, just let us know.
