🚀 Switching from RRO to PRRO: step-by-step guide for entrepreneurs in 2026

⏳ Until 2022, entrepreneurs used traditional cash registers (RRO). Today, more and more businesses are switching to software-based RRO (PRRO) — it's convenient, cheaper, and modern.

🔴 ❗️ From August 1, 2026 — new rules. The Ministry of Finance updates reporting requirements for individual entrepreneurs, clarifies simplified system criteria, and expands the list of transactions requiring RRO/PRRO. If you haven't switched yet — now is the best time.

🧠 What is PRRO?

PRRO (Programmable RRO) is an app on your POS terminal, smartphone, or tablet that performs the functions of a cash register:

• 📄 Records sales
• 🧾 Prints receipts
• ☁️ Transmits data to the tax service online

🎯 In one word: it's your cash register that lives inside an ordinary device.

📋 Step-by-Step Guide: Switching from RRO to PRRO

🗝️ EDP is your electronic signature. Registration is impossible without it.

Contact your bank or certification center:

• 🏦 PrivatBank
• 🏦 Oschadbank
• 🏦 ACC "Ukrzaliznytsia"

⏱️ Time: 15–30 minutes

Step 2️⃣: Register PRRO through the Tax Office Cabinet

1. Log in to the Taxpayer's Electronic Cabinet
2. Select "PRRO Registration"
3. Fill out form No. 1-PRRO
4. Sign with your electronic signature
5. 👉 After registration, you'll receive a fiscal number

⚠️ Important: make sure your EDP is valid. Validity is usually 1–2 years.

Step 3️⃣: Install PRRO on Your Equipment

Two options:

🔹 On your own:

💡 Tip: make a few test receipts on your first day to ensure everything works correctly.

🚦 How to Switch Without Stopping Trade

The most common mistake is removing the old RRO on day one and then rushing to set up the PRRO. Here's the safe approach:

1️⃣ Prepare your business unit

Check 20-OPP: object name, address, identifier — must match the actual payment location. Submit 1-PRRO and add cashiers via 5-PRRO.

2️⃣ Transfer nomenclature and sales logic

Not just products, but also tax groups, VAT, payment forms, discounts, returns. Check receipt printing, POS terminal operation, electronic receipts.

3️⃣ Run a pilot on one point or one cashier

The old RRO remains operational. You're just testing the PRRO in a real shift: opening, sale, return, Z-report.

4️⃣ Switch the main flow

Once the pilot is successful — switch sales to PRRO. Keep the old RRO as backup for a few more days.

5️⃣ Cancel RRO registration

Submit 4-RRO, have the device unsealed through a service center. Final step — only when the new system is stable.

💡 Key rule: a safe transition starts not with removing the old cash register, but with preparing the new one.

📌 What to Do with the Old RRO?

Cancel the old RRO registration:

1. Submit an application to cancel RRO registration (form 4-RRO)
2. Return the RRO to the supplier (or dispose of it)
3. Keep the documents — they may be needed during inspections

🏠 Note: some entrepreneurs keep the old RRO as a backup — that's also an option, but remember about annual maintenance.

⏳ Important: the service life of an RRO is 7 years from the date of manufacture. After that, the device must be written off.

🆕 What's Changing in 2026?

From August 1, 2026, updated rules take effect:

• New reporting forms for individual entrepreneurs — clarified simplified system criteria
• Expanded list of operations requiring RRO/PRRO
• Nova Poshta cash on delivery — income date = date of funds crediting, and the fiscal receipt must be issued before the customer receives the goods
• RRO exemption for mountainous settlements (turnover up to 500,000 UAH per year)

❓ FAQ

🔹 Is PRRO legal?

Yes. PRRO has been officially recognized by the Ukrainian Tax Service since 2020.

🔹 Can I have both RRO and PRRO simultaneously?

✅ RRO-to-PRRO transition checklist

To switch without stopping trade, follow these 7 steps:

• 1. Get a QES for the sole trader and for each cashier
• 2. Register the PRRO (form 1-PRRO) in the Tax Service cabinet
• 3. Add cashiers with form 5-PRRO
• 4. Set up the item list and tax groups
• 5. Connect the receipt printer and POS terminal
• 6. Run a pilot shift at one location or with one cashier
• 7. Deregister the old RRO (form 4-RRO) — only once the new setup is stable

💡 Golden rule: do not remove the old RRO until the PRRO has run in real mode for at least a few days.

🧠 Typical questions about moving from RRO to PRRO

— Can I keep using the old RRO after registering a PRRO? Yes. For a while both can run in parallel — that is exactly what a safe transition looks like.

— What about the old RRO's Z-reports? Print a final Z-report before deregistration and keep it — it may be needed during an inspection.

— Do cashiers need retraining? Yes, basic training takes 15–30 minutes. The Checkbox interface is simple and similar to a regular register.

— How much does the transition cost? PRRO registration itself is free. The main costs are the Checkbox plan (from UAH 0/month) and equipment (terminal + receipt printer).

— What about my item list, discounts and VAT? Migrate not only products but also tax groups, payment methods, discounts and return rules — otherwise receipts will be incorrect.

⚠️ Fines if you delay the transition

Selling without a fiscal receipt is fined by the Tax Service (Art. 163-15 of the Code of Ukraine on Administrative Offences):

💡 Switching to PRRO costs many times less than a single fine. And from 1 August 2026 there will be even more inspections.
