“Fiscal register” is the familiar business term and the name of ATK’s public information category. Current official documents distinguish Electronic Fiscal Equipment (PEF), Fiscal Systems and Electronic Fiscal Software (SEF). They serve the same broad goal of recording and fiscalizing sales, but they do not necessarily describe the same technical form.
The official terms used by ATK
Official materials refer to portable and non-portable fiscal registers, Electronic Fiscal Equipment, Fiscal Systems and Electronic Fiscal Software. Each has a specific meaning, so ask the provider for the exact category, certification or authorization status and installed version.
- Fiscal Register: equipment with fiscal memory and a fiscal seal.
- PEF/SF: the wider fiscal equipment or system category.
- SEF: electronic fiscal software certified and maintained under the applicable requirements.
- “Digital cash register”: common search language, not a separate formal category.
Equipment-led and software-led workflows
A PEF places the fiscal function in dedicated equipment or a tightly connected configuration. SEF implements the fiscal workflow in software and can connect the sale with items, inventory, operators, locations and reports.
A software solution can still require appropriate hardware, such as a thermal printer or scanner.
How to compare options
Compare the official category and status, equipment, offline behavior, maintenance, reporting and support—not only the initial price. Verify current requirements through ATK’s official material.
- Official category and status.
- Total equipment, installation and service cost.
- Training, maintenance and updates.
- Offline work and receipt traceability.
- Inventory, reporting and multiple locations.
Fiscal Register has a specific official meaning
Under Instruction 01/2026, a Fiscal Register is an electronic recorder equipped with fiscal memory and a fiscal seal. It is not the legal name for every POS app, even though businesses often use it as an umbrella search term.
PEF/SF is the wider equipment or computerized-system category and includes fiscal registers, fiscal printers and systems for specific activities.
SEF is certified software
SEF records and reports transactions automatically, creates the fiscal receipt and exchanges data with ATK. Its official identity includes developer, name, unique number, version and platform type.
The 22 June 2026 amendment requires installation and use on at least one suitable device or environment; it does not require one solution to be certified for every platform.
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 “digital cash register” an official ATK category? +
Not as a separate category in Instruction 01/2026. It is common language for digitization; the formal terms are Fiscal Register, PEF/SF and SEF.
Can any POS be used as SEF? +
No. The solution, version and platform used for fiscalization should match the relevant ATK registration and certification.
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.
