Slovenia — UJP B2G & Peppol BIS

UJP B2G universal since 2015 · No B2B mandate yet — regulator: Finančna uprava Republike Slovenije (FURS). Facts last refreshed: 2026-05-05.

Coverage model

Flowie operates a registered Peppol Access Point in this jurisdiction directly where we hold national accreditation, or via a vetted local partner registered with the in-country regulator where on-the-ground presence is required (KSeF, SDI intermediario, ZATCA service-provider, etc.). Either way, you call the same POST /v1/documents/send.

TL;DR

UJP (Uprava Republike Slovenije za javna plačila) is Slovenia's central B2G hub — mandatory since 2015.
No B2B mandate; FURS consultation underway with target 2027.
Format: e-SLOG 2.0 for legacy B2G; Peppol BIS 3.0 increasingly preferred.
Slovenia is also a launch user of the EU's ViDA pilot.

Background

Slovenia's UJP is a payments-and-invoicing hub: public buyers pay through UJP and receive invoices through it. The platform pre-dates Peppol but now bridges to it; Flowie's AP routes to UJP automatically when the recipient is registered.

Format profile

e-SLOG 2.0 for legacy UJP routes.
Peppol BIS 3.0 for new B2G and cross-border.
Slovenian VAT: SI + 8 digits.
