In Store Ordering with Deferred Payment Option

We would like to allow our showroom customers to place orders on our website using Snipcart. The thought would be to allow them to use the Deferred Payment Option. We would then take care of the credit card transaction through our own payment terminal.
Is there a way to limit who has access to the Deferred Payment Option?
Currently we send orders to NetSuite via Celigo via Webhook.
Does this scenario seem feasible?
