Technically yes, it would show in CCRIS that you paid; i.e. reflected in the payment history string.
However a point to note; most banks also evaluate the balance of one's credit balance against the credit limit granted.
If it's highly geared i.e. with high balance almost to the max of the line given, there are possibility that banks might also reject one's application for credit.

u have to pay on or b4 the due date,thats for sure,no grace period unless the due date has been extended by agreement between u and the financial institution

for safety,do pay your outstanding or minimum payment(agree by both party) on or b4 due date.then it should be show up 0 on your credit report.
above statement may be vary depend on the financial institution on their own credit rating,do check with the respective financial institution

for credit card make sure you don't pay late by up to 3 months, your card will be suspend under legal, after that it is very hard to reverse the status. if you default payment longer, some banks even freeze your savings, FD, current accounts, unable to withdraw. if ur having problems with your debt sort the help of akpk for credit cards. for loans, nego with the bank to lower the interest rate.

Added on January 3, 2009, 4:41 pmfor CC, it is okay to pay late about a month, but higher interest of Finance charge and Late charge will eat you up in the long run, so it is not a wise choice. plus if you pay late by a month the latest statement will add up ur min payment amount and full amount under past due, so u'll hav to pay more. just make sure you guys oay on time, if your dude date is before your pay day, call up the customer service to change your due date to 2,3 days after your pay day.

Let's say you just got the facilities today.
Next month 27th is the first time for you to serve the payment, but your salary are only credited on 28th.
Thus u only pay on 28th and repeat the same thing every month.

Your CCRIS will show that you are late for every month, but this is actually fine. Although you are late, but you are actually constantly serving the payment.
