E-invoicing via UJP

Entexia sends e-invoices via UJP directly from the Finance module — no separate software, no manual XML.

e-SLOG 2.0 is built in. You click send — the system submits to UJP and saves the confirmation. For Croatian companies: eSEF is in the same module.

How UJP e-invoice submission works

  1. 1

    Create an invoice in the Finance module as usual — the customer is a public body (ministry, municipality, public institution).

  2. 2

    Entexia recognises the public body and suggests UJP submission.

  3. 3

    You click 'Send via UJP' — the system automatically generates e-SLOG 2.0 XML and submits it to the UJP API.

  4. 4

    UJP returns a confirmation (submission ID) — the system saves it with the invoice. The audit trail is complete.

Frequently asked questions about UJP e-invoicing

What are e-invoices via UJP and who must send them?

UJP (Uprava za javna plačila — Public Payments Administration) is the Slovenian government portal for e-invoice exchange between companies and the public sector. Any company invoicing ministries, municipalities, public institutions or state-owned enterprises must submit the invoice in e-SLOG XML format via the UJP portal. This has been mandatory since 2015 — paper invoices are not accepted by public buyers.

Which e-invoice format does UJP require?

UJP requires e-SLOG format — an XML standard defined by the Slovenian Chamber of Commerce (GZS). Entexia generates e-SLOG 2.0 XML directly from the Finance module. No manual download, editing or upload to the UJP portal is needed — the system does it automatically.

Does Entexia send directly to the UJP portal?

Yes. Entexia connects to UJP via API and sends the e-SLOG XML directly when you click 'Send'. No XML file downloads or manual uploads required. The system stores a delivery confirmation for every sent invoice.

What about e-SLOG for private-sector customers?

e-SLOG and UJP submission are only mandatory for the public sector (B2G). For private customers (B2B), Entexia sends PDF invoices by email or generates e-SLOG for system-to-system exchange — depending on the agreement with the customer.

Do e-invoices via UJP work for Croatian companies?

UJP is specific to Slovenia. For Croatia, Entexia has built-in eSEF (electronic exchange of structured e-invoices) — the Croatian equivalent system for B2G e-invoicing. Both systems are in the same Finance module.

Do I need to buy an additional module for UJP e-invoicing?

No. e-SLOG generation and UJP submission are part of the standard Finance module — no extra fees, no separate subscriptions. Everything you need is included in the Finance module.
