B2B e-invoicing in Serbia
In Serbia, it has been mandatory to issue and receive electronic invoices for B2B transactions since 1 January 2023.
On the same date, select taxpayers became obliged to report their VAT to the Serbian tax authorities via the national e-invoicing system, Sistem eFaktura (SEF).
E-invoices must be in the UBL 2.1 format and securely stored for 10 years.
