QuickBooks offers two ways to manage your bills and bill payments: Write Checks and Enter Bills. Write Checks is the quickest way to record payments. It should be used when no bill is received or to pay bills as soon as you receive them. Enter Bills is the recommended way to enter bills in QuickBooks. It should be used for purchases that you receive and pay at a later time. You should never use Write Checks to pay a bill that was entered using Enter Bills. Any bills recorded using Enter Bills must be paid using Pay Bills.
