Slovenia has required suppliers to send invoices to public sector budget users as e-invoices through the UJP single entry and exit point since 1 January 2015. B2B e-invoicing becomes mandatory on 1 January 2028 under the Act on the Exchange of Electronic Invoices and Other Electronic Documents (ZIERDED), published in Uradni list RS no. 85/2025, which transposes ViDA Directive (EU) 2025/516. Exchange is decentralised through registered e-route providers, the Peppol network, direct system-to-system links or a free tax authority application, with no reporting of invoice data to FURS. VAT-registered businesses file electronic VAT ledgers for periods from 1 July 2025.

Decentralised (Peppol)
Decentralised exchange with no government pre-clearance and no reporting of invoice data to the tax authority, a model settled when the earlier proposal to report invoices to FURS within eight days was dropped.

Supervision is split under Article 23: UJP oversees e-route providers, the tax authority oversees the e-invoicing obligation itself, and the Market Inspectorate oversees the consumer rules. Public sector exchange continues to pass through the UJP single entry and exit point .
