Petruccelli says;
Find out when your balance is reported
Credit card companies have a “balance date,”
or the date they report your balance to the credit bureaus. Not surprisingly,
that date is rarely the same day as the date your payment is due. Thus you can
pay your balance off in full every month, but your credit report could still
reflect a balance. Contact your creditors, ask them when the balance date is,
and pay your bill before it.
