Invoice Correction Letter

An invoice correction letter is used to identify an error in an invoice and request or confirm the appropriate correction. It may be sent by a customer who received an incorrect invoice or by a business that discovered an error after issuing one.

Common corrections include incorrect quantities, prices, totals, invoice dates or numbers, billing details, tax information, payment terms, or descriptions of goods and services. The letter should identify the affected invoice, explain what is incorrect, state the correct information, and indicate the action required, such as issuing a revised invoice or making an appropriate billing adjustment.

When a business has issued the incorrect invoice, the letter can also acknowledge the error and explain that a corrected document has been provided. When the recipient identifies the problem, the letter should clearly describe the discrepancy and provide supporting information where necessary.

Keep the original invoice and relevant supporting records with the correction correspondence. Depending on the transaction, these may include a purchase order, delivery record, payment receipt, contract, or other document that helps verify the requested change.
