The Debit Note is a rectifying document that allows you to correct the value of an invoice when VAT has not been applied, or when the goods sold have been invoiced with a lower VAT rate than required.

For example, if an invoice is issued without applying the 23% VAT on certain goods, a Debit Note can be used to correct this mistake.

To issue a Debit Note, select the Invoice or Invoice-Receipt from the list of issued invoices and click on the "Add Debit Note" button. For the selected goods or services, indicate the difference between the VAT previously applied on the invoice and the correct VAT value and rate.

Important — this process can be simplified by issuing a Credit Note for the full value of the invoice, followed by issuing a new invoice with the corrected values.
