The changes affect the details and numbering of columns, the preparation of documents for financial leasing, as well as the deadlines for issuing corrected and restored electronic invoic --- From 13 October 2026, updated issuance rules and a new electronic invoice form will apply. The changes affect the details and numbering of columns, the preparation of documents for financial leasing, as well as the deadlines for issuing corrected and restored electronic invoices. What Has Changed in Electronic Invoices Accountants should take several changes into account. Certain details and column numbering have been revised in the new form. Therefore, the previous document template or an outdated version of the accounting software may not comply with the form effective from 13 October 2026. The procedure for completing electronic invoices for financial leasing transactions has also been changed. Organisations that process such transactions should check not only the appearance of the document but also the rules for transferring information from the accounting system to the relevant electronic invoice fields. The updates also concern the deadlines for preparing corrected and restored electronic invoices. The specific deadline should be determined under the applicable rules, taking into account the type of document and the circumstances of its issuance. Using previous settings or the customary procedure without verification is risky: the document may be generated incorrectly or fail to be sent. Why an Electronic Invoice May Fail to Send Following the form change, one likely reason for rejection is that the accounting software settings do not meet the new requirements. If an electronic invoice is not being sent, first check whether the latest update has been installed and whether the revised details are being completed correctly. Other reasons also occur in practice: - the system reports that the identification number and date are not unique because an electronic invoice with these details has already been registered; - the withdrawn electronic invoice has not yet been confirmed by the recipient, and the system continues to recognise the previously registered document; - the FEACN code has not been completed, or the old NCG code is being used instead of the new one; - the document remains in the “Queued for Sending” status because of stuck tasks in the data exchange queue. If a message about non-unique details appears, check the document history and the status of the previously issued electronic invoice. In the practical case described, the invoice was sent successfully after its number was changed; however, before taking such action, it is important to ensure that the new number follows the actual sequence of documents and does not create a duplicate. What the Accountant Should Check Before sending new documents and correcting previously prepared ones, it is advisable to carry out the following checks in sequence: - Make sure that the accounting software has been updated to reflect the form effective from 13 October 2026. - Compare the details and column numbering with the updated electronic invoice form. - Check the document completion requirements if the transaction involves financial leasing. - Confirm the applicable deadline if a corrected or restored electronic invoice is being prepared. - Check the mandatory product information, including the FEACN code, and replace the old NCG code with the new one where necessary. - If a non-uniqueness error occurs, locate the previously registered electronic invoice and check whether its withdrawal has been completed. - If the document remains in the queue for a long time, open the sending queue, remove the stuck electronic invoices from it, and resend the documents to the server. Before resending, it is useful to save the error message and check the document status in the electronic invoice system. Do not create identical documents repeatedly: this makes it harder to identify the cause and may result in multiple versions of the same transaction. If the error persists after the software update, compare the completion of the problematic electronic invoice with a document that was successfully sent using the new form. Pay particular attention to the revised fields, product codes, number, date, and the status of the data exchange queue. Frequently Asked Questions From what date does the updated electronic invoice form apply? — The updated form and issuance rules apply from 13 October 2026. Why does the system state that the electronic invoice number and date are not unique? — A document with these details may already have been registered, or the recipient may not yet have confirmed the withdrawal of the previous electronic invoice. Check the document history and status before changing the number. What should be checked if a product-related error occurs? — Make sure that the FEACN code has been completed and that the old NCG code has been replaced with the new one where necessary. What should be done if the electronic invoice has the “Queued for Sending” status? — Check the data exchange queue, remove the stuck documents, and resend them to the server. Does the accounting software need to be updated? — Yes, the settings and templates should be checked for compliance with the new form. An outdated configuration may prevent electronic invoices from being generated and sent correctly.
