I see payment methods under the system tab, other than that no...
I read this in the help section while in the backend:
Payment method : You will see here the name of the payment method selected by the customer during the checkout process. Once you changed it, a popup will open asking you more information about why you are changing it (great for later reference). If you want to notify the customer of the change, a notification email interface will also be displayed in that popup. Note that if you removed the payment view from the workflow of the checkout process, the customer will not be prompted to select a payment method and the dropdown won't be visible.
So what do i do if want let customer place orders but not get sent to the payment gateway during checkout without removing the payment option from the checkout workflow?
