No, you cannot reuse the same invoice number for security reasons. Once an invoice is voided, the next invoice will automatically be assigned the next sequential number. In cases where voiding is not an option, we recommend the following: ● If the entire invoice is incorrect (ex: invoiced the wrong customer), you should create an auto credit to cancel the invoice. ● If only the amount on the invoice is incorrect, you should create a credit note for the adjustment. By issuing credit notes, you maintain the integrity of your invoicing sequence and ensure compliance with accounting standards.
