payment terms

[sodapup]

We sell to wholesalers using Wholesale Gorilla in our shopify store.  I understand how to create payment terms in an order that already exists, however, I want to set up some of my customers with payment terms so that THEY can enter their order and have it automatically be assigned the agreed upon payment term.  This will allow their order to processed for fulfillment without our team having to manually enter their order and manually assign the terms.  Is there a way to do this...  To create default settings for certain customers so that they can enter their orders and have them automatically get the terms?  We are trying to push all order entry onto the customer so that we don't have to pay someone on our team to manually create the orders and assign terms.

Thank you in advance for any suggestions.
