SEF means Electronic Fiscal Software. It records sales, creates the fiscal receipt and reports data to the Information System of the Tax Administration of Kosovo. ATK uses Fiscal Registers as a public category, while official documents distinguish Electronic Fiscal Equipment (PEF), Fiscal Systems and Electronic Fiscal Software (SEF).
How fiscal registers, PEF and SEF relate
“Fiscal register” is the familiar umbrella expression. In ATK’s technical terminology, the implemented solution may be Electronic Fiscal Equipment, a Fiscal System or Electronic Fiscal Software.
easyPos is SEF and can be checked by company, software name, unique number, version and platform in ATK’s public register.
The role of SEF at the point of sale
SEF connects the cashier’s daily work with fiscal requirements. A sale is recorded, the document receives its identifiers and data is transmitted securely to ATK.
- Records goods and services.
- Creates a receipt with QR and NUIKF.
- Tracks delivery status and transaction history.
More than a till application
A business also needs items, prices, tax rates, operators, locations, stock and reports. A modern POS makes fiscalization part of the sale instead of a second task after it.
What to verify before starting
Ask how devices and operators are configured, what happens without internet, how corrections work and where pending receipts are monitored. Training and support should be part of the implementation.
The current 2026 legal and technical baseline
Administrative Instruction (MF) No. 01/2026 was published on 27 April 2026, entered into force on publication and repealed the 2018 instruction. It should be read with the specific requirements approved on 29 May and their amendment signed on 22 June 2026.
The June amendment replaces the corresponding baseline wording, including the supported-device requirement and treatment of untransmitted data.
Fiscal receipt or tax invoice?
Supplies to a final consumer require a fiscal receipt regardless of payment method. Supplies to persons engaged in economic activity use a tax invoice under applicable law, except where the buyer falls within the Instruction’s final-consumer definition.
The receipt is issued at payment, including prepayment. If supply occurs now and payment is contractually deferred, it is issued when the supply occurs.
What happens technically during fiscalization
SEF records the transaction electronically, signs the receipt with a private key and communicates securely with ATK’s Information System. A normal receipt is reported in real time and carries QR and NUIKF data for verification.
During an internet interruption, SEF continues issuing receipts, stores them chronologically and transmits them automatically after reconnection. A printed offline receipt is marked “OFFLINE”.
The 60-day clause is not a newly open deadline
Article 50 gave taxpayers without PEF/SF on the entry-into-force date 60 days from 27 April 2026 to install and use SEF. It is a historical transitional window, not a fresh period for each new reader.
Migration of existing PEF/SF users is set separately by ministerial decision, so a concrete business should check the latest official decision and ATK notice.
Turn the requirement into an operating procedure
Technical requirements need to become steps that staff can follow: who opens the shift, how connectivity is checked, when a sale is complete and who handles an unclear receipt status. Keep the procedure short, written and tested on the real device.
Define escalation as well. An operator should never improvise through deletion or duplicate entry; they should know when to stop and contact a supervisor or support.
What to request in a SEF demonstration
Do not watch only one successful sale. Ask to see communication status, receipt history, offline work, retry, correction and operator trace. Those scenarios show whether the solution is designed for a real working day.
- A clear status for each receipt.
- A distinction between local errors and an ATK response.
- History without silent deletion.
- A defined maintenance and support process.
Pre-launch check
Use this guide as a basis for discussion with your team and software provider. The actual setup depends on your activity, locations and internal procedures.
- Define items, tax rates, prices and payment methods.
- Set operator roles and shift responsibilities.
- Test sales, corrections, offline work and reports.
- Document the workflow and train staff before activation.
Practical questions
Is SEF simply a fiscal register on a computer? +
Not exactly. A Fiscal Register has a specific equipment-based definition, while SEF is software that records, signs and reports transactions electronically.
Is a receipt required for card payment? +
Yes for final-consumer supplies. In eligible cashless cases it may be delivered electronically with the buyer’s consent.
Where is SEF certification checked? +
Use ATK’s live public list and match company, SEF name and number, version, platform type and certification date.
Is generating a receipt enough? +
No. The workflow also needs identification, reporting, status, storage, corrections and an action trail under the applicable requirements and procedures.
Where should current SEF information be checked? +
Use official Tax Administration of Kosovo notices, guidance and channels because requirements and procedures may be updated.
How can I verify that a SEF is certified? +
Use the current register in ATK’s official portal and match the company, SEF name, unique number, version and platform to the proposed installation.
