Sometimes an error occurs on an invoice and your customer asks you to send a corrected invoice.
An invoice cannot be completely deleted, but the error can be corrected by creating a credit note and then issuing a completely new invoice with the correct information.
The invoice cannot be deleted because invoices must have a sequential numbering. This requirement for sequential numbering in invoicing is determined by the Accounting Act.
You can create a credit note by navigating in the UKKO system to “Incomes”, opening the invoice by clicking the three dots at the end of the invoice row, and then selecting “Issue credit note” from the menu.
Please note that before creating a credit note, any payment event on the invoice must be removed. The payment event can be removed in the transaction preview by clicking the trash bin icon next to the payment details.
If the invoice has already been approved for accounting, you must contact customer service to have the payment event removed.
If the original invoice was sent as an e‑invoice, email invoice, or letter, the credit note will be sent using the same delivery method.
