I am writing to address the late payment of the invoice issued on [Invoice Date] for the amount of [Invoice Amount]. Despite our initial agreement for prompt payment within [Payment Terms, e.g., 30 days], we are disappointed to inform you that the payment for the aforementioned invoice was received after the agreed-upon due date. Regrettably, late payment repercussions necessitate the enforcement of financial protocols. While your late payment has been acknowledged, our financial records require a return of the payment made for the invoice, as timely payment is essential to the smooth functioning of our business operations. Therefore, we kindly request you to process the return payment of [Late Payment Amount] to the following account: [Bank Account Details]. Moreover, I regret to inform you that based on the late payment, we are unable to honor the discount previously extended to you. As we strive to maintain fair and consistent practices with all our clients, late payments are not eligible for any discounts granted.
