Reporting & CTC model
clearance
Serbia has no Peppol Authority; the domestic mandate runs on the central SEF platform (Serbian UBL profile). Providers bridge SEF and Peppol for companies trading in both worlds.
Penalties
Fines from RSD 200,000 to 2 million for legal entities issuing or receiving invoices outside SEF where it is mandatory.

Frequently asked questions
Is SEF the same as Peppol?
No. SEF is Serbia's central national platform for domestic invoices. Peppol is the international network — Serbian companies use it for EU customers alongside SEF.
