This change aligns with Government Resolution No. 405 and Directive 2014/55/EU on e-invoicing in public procurement. The aim is to streamline public procurement, reduce bureaucracy, and ensure accuracy and confidentiality.
Both systems will not undergo a transition period, and you can submit invoices to SABIS through the SABIS portal, direct integration via API, or Peppol. The accepted invoice formats are Peppol BIS Billing 3.0 (Invoice and Credit Note) and Peppol BIS Billing CII Invoice. The SABIS TEST environment will soon be available to developers, with technical specifications provided on the official website.
Companies dealing with state institutions should prepare for this change and choose from three submission methods: manual entry, API integration, or using the Peppol network for cross-border e-invoicing compliance.
Businesses with direct integration into the Register Center must reconfigure their systems for SABIS, and the invoice format will change to European standard UBL XML, streamlining VAT calculation. Utilizing the Peppol network can automate processes, reduce errors, and improve efficiency. Adaptation to SABIS and considering the Peppol network are recommended before the deadline.
