Dear Sir/Madam or {{contact_person_name}},

We are writing in urgent response to your invoice, Invoice Number {{invoice_number}}, dated {{invoice_date}}, for the amount of {{invoice_amount}}, which we received on {{date_invoice_received}}. This invoice indicates an outstanding balance for goods/services that we believe have already been duly paid for.

Our records clearly indicate that payment for the aforementioned goods/services was successfully processed on {{payment_date}} via {{payment_method}} (e.g., EFT, bank transfer, cheque). The payment reference number associated with this transaction is {{payment_reference_number}}.

The amount paid was {{paid_amount}}, which settled the full balance due at the time. A copy of the proof of payment (e.g., bank statement excerpt, EFT confirmation, cheque copy) is attached to this letter for your immediate reference.

Request for Investigation and Correction

We kindly request that you conduct a thorough investigation into this matter within your accounting department. We believe there may be an administrative error on your part, as our records confirm that no outstanding balance remains for Invoice Number {{invoice_number}}.

Please reconcile your accounts to reflect the payment received and promptly furnish us with a corrected statement or confirmation that the matter has been resolved and no further action is required from our side regarding this specific invoice.
