How do I remove an invoice from Ukko Pro?
Old invoice lines cannot be deleted because the invoices have to have consecutive numbering. Consecutive numbering is determined by the accounting act so the only option is to make a credit note.
A credit note can be made by opening the invoice and clicking the ”Actions button", or the 3 dots shown on the right. After that you should see "Reimburse” on the list. If the original invoice has been sent as an e-invoice, email-invoice or as a standard letter, the credit note will be sent using the same method.
