How to invoice in Slovenia
A compliant Slovenian invoice (račun) must show the supplier's and customer's names, addresses and VAT/tax numbers, a sequential invoice number, the issue date and the date of supply, a description and quantity of the goods or services, the net amount, the VAT rate and amount, and the total payable. If VAT is not charged, state the legal basis for the exemption or reverse charge. Amounts are shown in euro (EUR), and invoices to public bodies (B2G) must already be sent electronically in the e-SLOG format.

- The client's name and address (and their VAT ID (ID za DDV) for reverse-charge or intra-EU supplies)
- A clear description and quantity for each line
- The net amount per VAT rate, the rate(s) applied and the VAT amount
- The total payable, in EUR

VAT & reverse charge
For cross-border work, the right wording matters. Invoice Forever offers ready-made Slovenian VAT notes such as:
- Invoice issued under the Slovenian VAT Act (ZDDV-1); DDV (VAT) charged at 22% unless a reduced rate or exemption applies.
- Intra-Community supply — exempt from Slovenian VAT under Article 46 of ZDDV-1 (Article 138 of EU VAT Directive 2006/112/EC); the recipient accounts for VAT in the country of arrival.
- Reverse charge — VAT to be accounted for by the recipient under Article 196 of EU VAT Directive 2006/112/EC (obrnjena davčna obveznost).
E-invoicing in Slovenia
Slovenia enacted the Act on the Exchange of Electronic Invoices and Other Electronic Documents (ZIERDED), which entered into force on 30 November 2025 and transposes the EU 'VAT in the Digital Age' (ViDA) directive. Mandatory B2B e-invoicing for domestic transactions begins on 1 January 2028 using a decentralised model (registered e-route service providers, the Peppol network, direct system-to-system exchange, or a free miniCheckout app for smaller businesses); B2G e-invoicing has been mandatory since 2015 in the e-SLOG format. The final law drops the earlier proposal for real-time reporting to the tax authority (FURS), and the 2028 start date is itself a postponement from the previously proposed 2027.
Invoice Forever can export a structured EN 16931 / Peppol BIS (UBL) e-invoice alongside the PDF (beta) — the format most of these mandates are built on. You still send it via your own access point, and some countries require their own national format.

Payment terms in Slovenia
Payment is normally made by SEPA bank transfer to an IBAN, quoting the invoice number as the payment reference. B2B terms of 30 days are the norm; the statutory maximum is 60 days for B2B and 30 days for public authorities, and statutory default interest applies to late payment.
Questions about invoicing in Slovenia
The standard VAT (DDV) rate is 22%. Reduced rates of 9.5% and 5% apply to certain goods and services such as food, books and medicines.
Yes. VAT-registered businesses must show their Slovenian VAT ID (ID za DDV) — the letters SI followed by 8 digits — and, for B2B supplies, the customer's VAT ID as well.
For B2G (public-sector) invoices, yes — since 2015 in the e-SLOG format. Mandatory B2B e-invoicing for domestic transactions is confirmed to begin on 1 January 2028 under the ZIERDED law; until then, e-invoicing between businesses is optional.
