In your online store, you can offer separate payment and shipping methods for resellers which won't be available to consumers.
To make payment and shipping methods available only to resellers:
Your online store now has a payment or shipping method that appears at checkout only if the customer is logged in and belongs to one of the selected customer groups. If you set the payment or shipping method as visible only in the reseller version, it won't be visible at checkout in other versions.
If you use a payment service, you should know that the credentials of many payment services can be used in multiple payment methods.
