What is PRRO and How to Set It Up: A Simple Guide
PRRO is a term that intimidates a lot of business owners, yet the idea behind it is genuinely simple. In this guide we explain in plain language what a software fiscal receipt registrar is, who has to use it, how it works and what it costs — no legal fluff.
What PRRO means in plain language
PRRO (software fiscal receipt registrar, Ukraine) is a program that replaces the traditional cash register. It issues fiscal receipts and automatically sends the details of every sale to the State Tax Service over the internet. Put simply: instead of a pricey physical cash register, you run an app on a smartphone, tablet or computer that does the same job — legally fiscalizing your sales.
Who is required to use PRRO
The requirement applies to almost anyone who takes payment from customers. In particular:
- Sole proprietors on the general tax system and most single-tax groups 2–4.
- Hospitality venues — cafes, restaurants, bars and coffee shops.
- Retail — shops, supermarkets and kiosks.
- Service businesses that take cash or cards from customers.
- Online stores and delivery services with cash-on-delivery payment.
How PRRO works
When you sell a product or service, a POS with PRRO generates a fiscal receipt with a unique number and a QR code. That receipt is registered on the tax authority's server right away. The customer gets a paper or electronic receipt (by phone, email or QR). At the end of the shift a Z-report with the totals is produced. It all happens automatically — you don't have to send anything by hand as long as you have internet.
How to set up PRRO
The general steps are: obtain a qualified electronic signature (QES), register the till and cashier in the taxpayer's online office, and connect PRRO inside your POS. The easiest route is to pick a POS with PRRO already built in: a setup wizard handles most of the steps and support helps with registration. You don't need to buy a separate cash register.
Free PRRO in Skyservice POS
In Skyservice POS, PRRO is built in and free on every plan — you don't pay separately per till or hand over a percentage of receipts, the way many competitors charge. Fiscalization, Z-reports, sending data to the State Tax Service, receipts by SMS or QR — it all works out of the box. That noticeably lowers the real cost of automation, since standalone PRRO in other systems can run 100–200 ₴/mo per till (~€2–5).
Penalties for operating without PRRO
Trading without fiscalization when it's mandatory risks fines:
- For a sale not run through PRRO — a sizable fine based on the transaction amount.
- Repeat violations are punished more harshly — up to multiples of the amount.
- Systematic breaches can trigger inspections and a shutdown of operations.
- Reputational risk and complaints from customers who never got a receipt.
- The exact fine amounts change — check them against the current State Tax Service legislation.

Frequently asked questions
Can I operate without PRRO?
No, not if your activity falls under the fiscalization requirement (most sole proprietors and businesses that take payment from customers). Operating without PRRO when it's mandatory risks substantial fines. Exemptions and reliefs are worth confirming against the current State Tax Service legislation for your group and type of activity.
How much does PRRO cost?
The PRRO software from the tax authority itself is free, but most POS systems charge for integrating it — often 100–200 ₴/mo per till (~€2–5) or a percentage of receipts. In Skyservice POS, PRRO is built in and free on every plan, which lowers the real cost of automation.
How is PRRO different from a regular cash register?
A classic cash register is a physical device you have to buy and maintain. PRRO (the software kind) is an app on a smartphone, tablet or computer that performs the same fiscalization function but without the expensive hardware. PRRO is cheaper, more portable and easier to set up.
