It is very important to pay an online credit card bill. By paying an online credit card bill on time every month, a person will always make sure that his or her credit score remains high. If a person forgets to pay this sort of bill, then it may be likely that he or she has to pay some sort of late fee. A credit card company may also report one to a local credit bureau, which would mean that a person's credit score would then be knocked a lot of points for failing to make a minimum payment in a month.
