In most cases they are a customer.
But there may be instances where this is not the case:
- They order Items where there is no stock available, and we cannot fill the order. The client may not want to create them as a customer (yet)
- This may be repeat business, and we do not want to create another Customer record where one exists already. The client does not have a log-in for existing customers (yet).
- Until they approve the Order, we do not want to create the Customer. (There has been a few attempts at fraud in the past.)
