Step-by-step explanation:
When a referral order is honored and credit is given to the shipping base, a type of business transaction occurs commonly known as a referral credit or referral reward. This practice is a part of a referral program where existing customers, affiliates, or partners are rewarded for bringing new customers to a business. The shipping base, in this context, is likely the location or the entity that initiated the referral. As a result, this entity receives credit which can often be in the form of discounts on future purchases, cash rewards, or other incentives.
