< Back to E-Invoicing Overview
Croatia has fully integrated e-invoicing into its public administration system, making it a requirement for all government suppliers. The country’s efforts to digitize financial processes align with broader European Union directives, ensuring transparency, efficiency, and compliance with tax regulations.
While e-invoicing is not yet mandatory for B2B transactions, Croatia has actively encouraged private sector adoption. Businesses that integrate e-invoicing into their financial operations benefit from reduced administrative costs, faster processing times, and improved accuracy in VAT reporting. Peppol has been widely adopted to facilitate both domestic and cross-border transactions.
