If you made up the missed payment before the end of the month, the payment will not be reported as late to the credit bureaus. If a previous missed/late payment was made up, we will report to the credit bureau that you've now made up your late payments so they can update your credit report to show that it is back in good standing.
Please note that the credit score impacts of a late payment can't be reversed. The credit bureau tracks your payment history and because you were in fact late in making your original payment, your credit score will be impacted even once you've made up a payment. However, by making up a missed payment, you will stop your credit score from further decreasing.
