You are the manager of the Accounts Receivable Department for a merchandising business. Your billing clerk sent a bill for $ 2 to a customer who had charged $ 100 in goods (including sales tax) with terms 2/10, n/30. The customer called and indicated his displeasure; he can’t understand an error like this because he paid on time. Explain to your billing clerk why Accounts Receivable is credited for $ 100 and not $ 98. How was permission given to send less than the full amount?
