The Finalization is the process by which the actual purchase amount is funded from the credit card. At the same time, any tips that the customer wishes to give to the employee are added to the final amount.
IMPORTANT! Do not skip the finalization process. Otherwise, the transaction will not be funded. The merchant will lose the value of the sale and the employee will lose on the tips.
IMPORTANT! It is not strictly necessary to have the customer sign this last copy of the transaction record. However, it is strongly recommended to do so if the customer made mistakes while filling the tip and total lines on the original copy. This could protect the merchant against chargebacks.
