In Serbia, e-Invoicing implementation began in May 2022 with B2G and G2G transactions and is still ongoing with G2B and B2B transactions. Sistem E-Faktura, Serbia’s national e-Invoicing platform, is a prime illustration of the global clearance model.
- The digital signature on invoices is optional. The API key is sufficient for authentication when sending invoices.
- As of May 2022, private sector entities must issue and process e-Invoices to public entities for B2G transactions; as of July 2022, they must receive and store e-Invoices issued by public entities for G2B transactions; and as of January 2023, they must issue and store e-Invoices between private sector entities for B2B transactions.
- VAT-registered persons are required to report to the system in cross-border transactions, however, they are excused from reporting if the invoice is issued by a VAT-exempt entity.
- The purchaser has 20 days to accept or reject the portal’s electronic invoice.
- For test and production systems, taxpayers must submit separate applications and generate unique API keys. The duration of an e-Faktura API key is unlimited after it has been generated.
