An honest comparison

Tezga or a traditional fiscal cash register?

Both are legal. The difference is where the receipt is fiscalized, what you buy and what happens when the internet goes down. Here we describe both sides as they are, including the cases where a fiscal device is a better choice than us.

Online register

A phone, tablet or computer, and the receipt is fiscalized by the Tax Administration's V-PFR over the internet. This is how Tezga works.

Traditional register

A fiscal device on the premises, with its own processor (L-PFR) and a smart card. It issues receipts even without a connection.

Row by row

Question	Online register (Tezga)	Traditional register with a device
What you buy at the start	No equipment. It runs on the phone, tablet or computer you already have, with no installation and no onboarding cost.	A fiscal device, from a supplier approved by the Tax Administration. The price depends on the model and the supplier.
Monthly cost	From 990 RSD a month, paid in advance for 3, 6 or 12 months, with no fixed-term contract. Up to 3,000 fiscal receipts a month are included.	Depends on the supplier: maintenance, service and the software with the device are set by its terms.
Where the receipt is fiscalized	On V-PFR, the Tax Administration's virtual processor, over the internet. Tezga can also work with an approved supplier's L-PFR.	On the processor in the device itself (L-PFR), with a smart card for those premises.
When the internet goes down	Through V-PFR a receipt cannot be issued and sales stop until the connection returns. With an L-PFR, receipts are issued even without a connection.	A device with an L-PFR issues receipts even when there is no connection.
A shop, salon or venue	V-PFR alone is enough for sales exclusively over the internet. For turnover on business premises the law requires, alongside V-PFR, at least one L-PFR in each premises.	A device with its own processor (L-PFR) on the premises meets that obligation.
What it runs on	A phone, tablet and computer. The same account works on several devices at once, in the field and in the shop.	On the device itself, where it stands.
Printing receipts	A PDF on an 80 mm roll or on A4, sent to the printer through a driver or a printer app. The customer can also get the receipt by link and by QR code.	The printer is usually part of the device.
The security element	Your Tax Administration certificate as a .pfx file, with a password and a PAK. It is stored encrypted and never shown back.	A smart card in the device.
E-invoices, statements, reports, web shop	In the same account, by plan: e-invoices on SEF, bank statements, reports that reach your accountant on their own and a web shop that fiscalizes itself.	Depends on the supplier. The device issues fiscal receipts; for the rest, check what you get with it.

Online register (Tezga)

In the same account, by plan: e-invoices on SEF, bank statements, reports that reach your accountant on their own and a web shop that fiscalizes itself.

Traditional register

Depends on the supplier. The device issues fiscal receipts; for the rest, check what you get with it.

Business premises change the maths

The Law on Fiscalization, Article 6, paragraph 4: anyone who chooses V-PFR but does not carry out turnover exclusively over the internet must have, in each business premises, at least one device with its own fiscal-receipt processor, that is, an L-PFR.

For a shop, salon or venue this means that not even an online register works without an L-PFR on the premises. So the question is not only "a device or a phone", but also who will give you an L-PFR.

A third way: Tezga with an L-PFR. Tezga already works with an L-PFR from any supplier approved by the Tax Administration, together with the smart card for those premises. You set it up in Settings, Fiscalization, and receipts are then issued even without the internet.

Check your case in the fiscal guide

An online register makes sense when…

You sell over the internet: then V-PFR alone is enough, and an order from your site becomes a receipt without retyping.
You work in the field, on delivery or at the customer's, so a register in your phone is more practical than a device.
Alongside receipts you also need e-invoices, bank statements and reports for your accountant, in one account.
You do not want to buy a device before you see how the business goes: the subscription starts from three months, with no fixed-term contract.

A traditional register is the better choice when…

You work in a shop or venue and need only a register. The law requires an L-PFR on the premises anyway, so a single device that does everything can be simpler than two parts.
The internet on the premises often drops, and every minute without a receipt is a queue at the till. A device with an L-PFR issues receipts even without a connection.
At the counter you want a single unit with a built-in printer, without a phone, a tablet and print settings.
You have only an iPhone or an iPad, and you need a paper receipt and a scanner: in Safari, camera scanning does not work, and printing needs an AirPrint printer.

If you recognise yourself here, get a device. When you later need e-invoices, reports for your accountant or a web shop, Tezga works with an approved supplier's L-PFR too.

The fastest way to decide is to see the register in action, with the real screens.

Frequently asked questions

Is an online fiscal register as legal as a traditional one?

Yes, if its ESIR is approved by the Tax Administration. Tezga is an approved ESIR under number IB 1597, by decision of the Tax Administration no. 000-092-00-00123/2026-0000 of 3 July 2026.

Does a shop need a fiscal device alongside an online register?

For turnover on business premises the Law on Fiscalization (Article 6, paragraph 4) requires, alongside V-PFR, at least one device with its own processor (L-PFR) in each premises. Tezga works with an approved supplier's L-PFR, so you do not change your software. Check your case with your accountant.

Which is cheaper, an online register or a fiscal device?

An online register has no upfront equipment cost: Tezga starts from 990 RSD a month, paid in advance for 3, 6 or 12 months. The price of a device and its maintenance comes from the supplier, so compare the total cost over a year, not just the first month.

Does an online register work without the internet?

Through V-PFR, no, because the receipt is fiscalized on the Tax Administration's side at the moment of issue. With an approved supplier's L-PFR and a smart card for the premises, Tezga issues receipts even without a connection. Mobile internet on the phone is enough for V-PFR.
