As of the 1st of January 2015 in Slovenia it will be mandatory to receive e-invoices for Public Administration. All domestic suppliers of government and public administration will have to submit only electronic invoices. Therefore, payments based on paper invoices will not be executed. Slovenian government, national chamber of commerce, tax administration and banks have agreed about the national e-invoice standard (eSlog XML), which is based on international GS1 standard with PDF visualization.
Delivery of e-invoices for Public Administration will be possible only through the government EDI network hosted by Public Payments Administration (UJPnet) or eInvoice UJP portal. Mail, fax, local upload or other similar routes of delivery will not be permitted.
More than 40% of companies in Slovenia have already integrated EDI and e-invoices in their ERP systems. ZZI is most widely used EDI provider in Slovenia connected to UJPnet.
