Everything You Need to Know About Fiscal Cash Registers in Slovenia

If you have just opened your s.p. (sole proprietorship), you will likely soon encounter the system of fiscal cash registers (davčna blagajna). This is a system where your cash register (a program on a computer, phone, or tablet) is directly connected to the Financial Administration of the Republic of Slovenia (FURS) via the internet. When you issue an invoice for a payment made in cash or by card, the data for that invoice is sent to FURS in real-time, where it is verified and stored.

When is Fiscal Verification Mandatory?

You must fiscally verify an invoice if you sell goods or services and the customer pays with cash. Under "cash payments," FURS includes not only banknotes and coins but also all payment cards, checks, and vouchers. Conversely, you do not need to fiscally verify an invoice if the customer pays via a direct transfer from their transaction account to your s.p. account (e.g., via online banking or a UPN slip). Therefore, if you operate exclusively through bank transfers (B2B business), you do not need a fiscal cash register.

Steps to Successfully Set Up your Fiscal Cash Register

Setting up a fiscal cash register might sound technically complex, but the process is actually quite logical and structured. Follow these key steps:

• Obtain a Dedicated Digital Certificate: This is the first and most important step. It is a special certificate intended exclusively for the fiscal verification of invoices. You submit the request for free via the e-Davki portal. Once approved, you will receive a reference number and a password to install the certificate on your device.
• Choosing Software or a Provider: You must decide how you will actually issue invoices. Options include mobile apps (ideal for field work, e.g., contractors or mobile hairdressers), computer programs for office work, or the  FURS "Mini blagajna" app for those with a small number of invoices.
• Preparation of Internal Acts: As an entrepreneur, you must adopt an Internal Act on the census of business premises, the assignment of business premises codes, and the rules for assigning sequential invoice numbers. You do not need to send this document to FURS, but you must keep it at your place of business for potential inspections.
• Registering Business Premises with FURS: Before issuing your first invoice, you must report your business premises data to FURS. This is usually done directly through your chosen software. If you do not have a fixed office, you list the premises as type "C" (movable object).
• Posting the Mandatory Notice: In the area where invoices are issued (or in a visible spot in the field), you must post the official "Take the Invoice" (Vzemite račun) notice, which can be found and printed from the FURS website.
• Testing and the First Invoice: Once you upload the certificate and set the parameters (tax ID, VAT rates, internal act), issue a test invoice. Check that the ZOI, EOR, and QR codes are visible at the bottom—these are proof of successful verification.
