Fiscalization and POS,term by term.

The ATK-certified program that fiscalizes the sale inside the system itself.

A SEF records the sale, signs it digitally and sends it to ATK straight from the program, with no extra fiscal device. For a program to be called a SEF, ATK’s commission evaluates and certifies it and lists it in the public register. Kendrix POS is a certified SEF (no. 812113983327).

Registering every sale with ATK at the moment it happens.

In online fiscalization the receipt gets its fiscal numbers from ATK and the verification QR code in real time. Without internet, the receipt prints marked OFFLINE and is sent automatically once the connection returns.

The receipt issued by a SEF, carrying ATK’s numbers and a QR code.

Besides items, quantities, prices and VAT by rate, a fiscal receipt carries the business details (NUI), the fiscal number NIVF, the verification number NUIKF and the QR code with which the customer verifies the receipt on ATK’s site.

The fiscal number ATK returns for every registered receipt.

At the moment of sale the SEF sends the receipt to ATK and receives the NIVF, which is printed on the receipt. It proves the receipt was registered in ATK’s system.

The verification number of the fiscal receipt, printed alongside the NIVF.

The NUIKF uniquely identifies the receipt and is used, together with the QR code, to verify it. In the Kendrix POS mobile app every receipt carries a NUIKF and a QR.

The code the customer scans to verify the receipt on ATK’s site.

The QR code links the printed receipt to its registration at ATK. Scanning it opens ATK’s verification page showing the receipt’s data — full transparency for the customer and for inspections.

The interim summary of a shift, without closing it.

The X report shows sales totals, payments by method, VAT by rate and the cash position up to that moment. It can be produced any number of times during the day; it does not reset the figures.

The Z report closes the period: final totals, payments, VAT by rate and the cash position. In Kendrix POS the X and Z reports meet ATK’s requirements and are produced in one click.

The three rates a fiscal receipt in Kosovo works with.

Every item or service carries its own VAT rate and the receipt splits the total by rate. Which rate applies to which goods is set by VAT legislation — ATK keeps the current list. In Kendrix POS the rates come preset according to ATK’s rules.

The classic fiscal device with its own memory, the predecessor of the SEF.

A fiscal cash register is hardware: a till or printer with a fiscal module. A SEF is certified software that does the same job inside the point-of-sale program, on an ordinary computer with a receipt printer, and adds the verification QR code.

Where receipts wait when there is no internet, until they are sent to ATK.

When the connection drops, the receipt prints marked OFFLINE and joins a secure queue. As soon as the internet returns, Kendrix POS sends the queue to ATK by itself, within the legal deadlines, with no action from the cashier.

The business registration number, printed on every fiscal receipt.

The NUI identifies the business with ATK and the business registry and appears on receipts, invoices and in the SEF register. Kendrix Tech L.L.C.’s NUI is 812307975.

The program (and devices) with which a sale is made at the till.

A POS program records items, payments, discounts and returns, prints the receipt and produces reports. When the POS is a certified SEF, the receipt is fiscal. Kendrix POS has restaurant, market, clinic and quick-sale modes.

Corrections to a fiscal receipt, linked to the original receipt.

A return gives back specific items with a quantity and refund method; a cancellation voids the receipt with a mandatory reason. Both are linked to the original receipt and reported to ATK automatically.
