Fiscal verification of invoices in Slovenia
Fiscal verification in Slovenia applies to invoices settled by cash payment, a term that covers payment cards and cheques as well as banknotes. The invoice must be sent to the tax authority as it is issued, receive a unique identifier, and print that identifier together with a QR code on the receipt. Bank transfers are exempt.
Fiscal verification of invoices is a common source of uncertainty for service businesses in Slovenia. A hair salon that takes card payments and a consultant who invoices for a bank transfer have completely different obligations, even though both issue an invoice for a service.
This article explains the logic that determines the obligation and what it means day to day. It is not legal advice: for your specific situation, consult your accountant or check directly with the Slovenian tax authority (FURS).
What fiscal verification means
The procedure requires that every invoice you issue against a cash payment is transmitted electronically to the tax authority at the moment it is issued. FURS confirms it and returns a unique identifier, which you print on the receipt alongside the issuer's protective mark.
The purpose is not to tax the individual service but to make it impossible to delete or alter an issued invoice without leaving a trace. A customer can scan the QR code with an app and confirm the invoice was genuinely reported.
When the obligation applies
What matters is how the invoice was paid, not what it was for. The legislation interprets "cash payment" more broadly than most business owners expect.
| Payment method | Fiscal verification |
|---|---|
| Banknotes and coins | Required |
| Debit or credit card on site | Required |
| Cheque | Required |
| Other similar payment instrument | Required |
| Bank transfer against an issued invoice | Not required |
This has an important consequence. A salon that accepts cards needs fiscal verification. A consultant who invoices every engagement and is paid by transfer does not. A business that does both needs verification for the portion of revenue settled in cash.
What you need in practice
Electronic fiscal verification requires three things:
- A dedicated digital certificate, obtained through the eDavki portal. It is not the same certificate you use to log in to eDavki.
- Software that transmits the invoice to FURS on issue and writes the returned identifier onto the receipt.
- An internal act describing your business premises and how invoices are numbered.
Alongside the electronic route there is also the bound invoice book, a pre-certified book of printed invoices. It is useful as a fallback during connectivity outages and for businesses with very low cash volume, but it requires reporting the issued invoices afterwards.
What happens when the connection drops
Losing internet access does not stop you issuing an invoice. You issue it with the issuer's protective mark but without the FURS identifier, then report it within the prescribed window once connectivity returns. This is exactly why keeping a bound invoice book in a drawer is sensible, even if you never open it.
How this connects to booking
In a service business, the invoice almost always follows a completed appointment. If the calendar and the invoicing tool are separate systems, you enter the same service twice, which is the single most common source of errors in pricing and customer data.
In Calendra, a completed appointment becomes an invoice with the service, price and client details carried over, and fiscal verification is available as an add-on for businesses that take cash payments. There is more detail on the Invoicing and payments page.
Common misconceptions
"If I invoice zero, verification is not required." A free service is not a cash payment, but the record-keeping rules differ. Check with your accountant how to treat gift vouchers and their redemption.
"A card payment is not cash." Not in everyday language, but under this law it is treated as a cash payment. This is the mistake salons make most often.
"An online deposit is a transfer." It depends on the payment route and on when you issue the invoice. This is worth settling with your accountant before you start collecting deposits.
What to do this week
Write down what share of your revenue is settled on site and what share arrives by transfer. If the on-site share is above zero, you need a fiscal verification solution. If it is zero, your obligation is considerably simpler than you may think.
Then check whether your current system creates the invoice from the appointment or whether you enter it separately. If you enter it separately, that is where you will save the most time. Look at the pricing, or read how client management keeps issued invoices visible in the customer's profile.
