How to fix a bill if by mistake you added two times the same amount of money as payment?

Whenever you by mistake entered twice or incorrect amount of money extra as payment, you will get the amount of extra money in red numbers and you will see the same amount of money as negative value under “Insert transaction” in the “Sum ($$$ including tax):”.

 To fix this you will need to:

• In the system go to the bill of the booking you want to fix
• in the  “Sum ($$$ including tax):” should be in negative the amount to be registered in order to fix the bill
• Select the same payment method that where you registered extra money on
• Add the transaction
• Close the bill if no more payment is going to be registered.
