how do managers resolve problems related to transactions including cash, checks, debit cards, credit cards, discounts, layaway, Cash on Delivery, returns, gift certificates, and automatic fee withdrawals?

Explanation:

In order to solve such problems the managers analyze the financial transactions in their systems. They first obtain the transaction number that the client received upon making the purchase. Then they find this transaction number in their system and analyze the numbers. If the transaction was a mistake or had an error they can reverse the transaction which would return the money to the client and move that transaction off of the confirmed transactions in the system.
