If you're already using a credit card at the beginning of whooing, setup is a bit difficult. You have to deal with the following things.
-At the beginning, the estimated billing amount in real time is investigated and registered as the basic balance. -Investigate the remaining installments at the beginning, and register the remaining installments by entering monthly installments (Description of monthly installments note)
And even if you register and start with the basic balance of your credit card, some of the above may be misaligned. This is because some things that have been paid but have not yet been approved by the credit card company are applied after a day or two.
