This could be for a few reasons.
First, please double-check the date on the late notice versus the date your payment cleared. Very often late notices and payments cross each other in the mail.
Second, please review the statement attachment to the late notice, and log into the Resident Center and click Payments if you need to see more of your account history. It’s possible you have an outstanding balance from previously and your payment didn’t sufficiently cover it.
Third, if you paid via online banking, please be advised these are not true electronic transactions. A check is sent on your behalf from your bank, which does make it subject to the same potential issues with USPS had you mailed a paper check yourself. Please also be advised, some banks will show the payment as “cleared” on your end either as soon as they send the check or when they believe the check will arrive. The only way to pay from truly electronic means is through the Resident Center, and payments made using a bank account’s routing and account number carry no convenience fees and are instantly credited to the account.
