Shipping Question

Let’s say you have a customer that has 100 ShipTo’s. And all shipping charges are paid by the customer and sent on the customers carrier discount number. If all you had listed was the shipping info under Customer Maintenance–>Billing–>Detail–>Shipping terms filled in, would everything on that account ship on that number? Or does it have to be on every shipto?

I am wondering if the logic is If ther is no ShipTo Manifest info, then ship according to what on the Billing–>Detail tab.
