Croatia has joined the European countries that mandated the use of e-invoicing in public procurement processes as outlined in Directive 2014/55/EU.
From 1 December 2018 all contracting parties must accept and process e-invoices if received from their suppliers in public procurement procedures. From 1 July 2019 e-invoicing will be mandatory in public procurement procedures.
All invoices issued in public procurement must meet the European standard EN 16931-1:2017, issued by the European Committee for Standardization (CEN) on 28 June 2017. The Croatian government recommends the use of the OASIS UBL 2.1 standard for B2G public procurement, however, the Cross-Industry Invoice (CII) is an accepted alternative.
