The invoice does not become valid the moment it is printed. It only becomes a tax document once it is sent to the e-invoicing platform and receives the unique NIVF number. Until then, it is an unfinished document, regardless of whether it has been signed, printed, or sent by email.
This page shows what a fiscalized invoice contains, how NIVF and NSLF work, how to obtain and renew an electronic certificate, within what timeframe each type of invoice must be sent, how much an unfiscalized invoice costs, and how to correct an incorrectly issued invoice.

Fiscalization is the system that sends the invoice to the tax administration in real time and returns the unique number that makes it valid. Without fiscalization, the business buyer cannot deduct the expense, and the seller is left with a sale without acceptable proof.
The obligation to issue a fiscalized invoice includes income tax payers, taxpayers of personal income tax from business, VAT-registered entities including non-profit organizations, public bodies, their suppliers, and non-residents with a tax representative. Exemptions are few and defined, namely agricultural producers, public urban transport tickets sold by the driver, and street vending activities.
The fiscalized invoice is also the primary document for recognizing the expense in income tax. This is the link that often goes unnoticed, because a completely real expense without a fiscalized invoice is not deductible.

The invoice must include 14 mandatory elements. Among them are the unique invoice identification number, called NIVF, the issuance system number, called NSLF, and the QR code that allows anyone to verify the invoice.
| Element | What does it show? |
|---|---|
| Not in the Federal Vacations Act | The unique invoice number returned by the platform after fiscalization. |
| National Sports and Leisure Federation | The release system number, i.e., the software solution that issued the invoice. |
| Kodi QR | Allows anyone to verify the invoice without system access. |
| Buyer's information | Mandatory when the individual invoice value exceeds 500,000 lek. |
The buyer's data is always recorded when the buyer is a business, and in any case when the value of an individual invoice exceeds 500,000 lek. In exports to an individual, his identification number and address are recorded.
The invoice is only valid once it's been fiscally registered and assigned an NIVF. If the program you're using prints an invoice without sending it to the platform, you haven't invoiced; you've only printed.

Fiscalization is carried out using an electronic certificate that links the business to the central invoice platform. The certificate is installed in the software solution you use, and without it the invoice cannot be fiscalized.

Note. The procedure for obtaining the electronic certificate, its validity period, and its renewal must be verified. UNVERIFIED, must be confirmed before publication. The applicable framework is Decree No. 431/2020 for the central platform, Decree No. 239/2020, Decree No. 220/2020, and UMF No. 16/2020.
As a practical recommendation, schedule the certificate renewal on your calendar two weeks before it expires. The certificate's expiration date triggers billing suspension, and billing suspension halts sales, so this is the most expensive date to forget all year.

| Case | Deadline |
|---|---|
| Supply of goods or services | The invoice is issued at the time of supply. |
| Received prepayment | Invoicing within 72 hours |
| Monthly billing | By the 10th of the following month |
| Self-billing for services received from abroad | By the 10th of the following month |
| Taxation of import invoices | Within 7 days |
| The sales book and the purchase book | By the 11th of the following month |
| VAT declaration | By the 14th of the following month |
The 7-day deadline for imports and the 11th deadline for books stem from changes to the fiscal package, which take effect on January 30, 2026. Previously, imports were fiscalized within 3 days.

The first consequence isn't the fine; it's the unrecognized expense. The business buyer is left without a valid document, so they lose the VAT deduction and the expense recognition for income tax purposes.
A VAT-registered business records a 600,000-lekë expense excluding VAT based on an unfiscalized invoice. The expense is not recognized, so taxable profit increases by 600,000 lekë and the 15% tax results in an additional 90,000-lekë liability. Together with the deductible VAT that is lost, 600,000 lek at 20% yields 120,000 lek, bringing the total cost of a single invoice to 210,000 lek.
| Violation | Fine |
|---|---|
| Non-issuance of invoice | 25,000 / 50,000 / 75,000 lek according to the category |
| Failure to issue the invoice, second time | Fine of 50,000 / 100,000 / 500,000 lek and a 30-day business suspension. |
| Failure to issue the invoice, third time | Criminal prosecution and publication of the name |
| Failure to submit the invoice for fiscalization | 25,000 / 50,000 / 75,000 lek |
| Violations of electronic invoicing rules | 50,000 / 100,000 / 150,000 lek |
| Incorrect invoice | 50% of the tax effect, or 10,000 lek when there is no effect. |
| Failure to record data in the system | 25,000 / 50,000 / 75,000 lek |
| Buyer's failure to pick up the invoice | 50,000 / 25,000 / 1,000 lek according to the entity |
The fine for an obligation does not exceed 100% of the obligation's value. This is the limit under Article 111(5), which applies even when multiple violations concerning the same obligation are aggregated.
Attention. The exact breakdown of taxpayer categories for the amounts of 25,000, 50,000, and 75,000 lek should be verified. UNVERIFIED, must be confirmed before publication. The amounts have been verified in Articles 122, 123, 124, 124/2, and 125 of Law No. 9920/2008.

A fiscalized invoice is neither deleted nor rewritten. It has been assigned an NIVF and is on the central platform, so the error is closed with a second document that refers to the first one and is fiscalized in the same way.
The procedure we follow with clients is as follows. The incorrect invoice is identified along with its NIVF, a corrective document referencing that NIVF is issued, it is sent for fiscalization, and finally the sales book for the period is checked to ensure the correction is reflected before the 11th.
Attention. The exact type of correction document, the reference field to the original invoice's NIVF, and the deadline by which the correction must be submitted for fiscalization must be verified. UNVERIFIED, must be confirmed before publication. No figures or deadlines for this section will be published without confirmation.
When a correction changes the VAT amount for a closed period, the effect doesn't end with the invoice. It carries through to the books and the period's return, so corrections are made before the 11th and not left until the end of the quarter.

The invoice is printed by a program that doesn't send it for fiscalization, and the business thinks it has issued an invoice.
The electronic certificate expires and billing stops at the most inconvenient time because the renewal wasn't planned.
Payment is collected in advance and the invoice is held until the service is completed, with a 72-hour turnaround.
Import invoices are fiscally processed under the old 3-day deadline, while the current deadline is 7 days.
The buyer's information is not included on an invoice exceeding 500,000 lek, and the buyer is left without a complete document for the expense.
The incorrect invoice is being attempted to be deleted from the program, while it resides on the central platform and requires a correction document.
The monthly periodic billing is sent after the 10th because the deadline conflicts with the bookkeeping date.
The expense is recorded on an invoice without VAT, and the discount is applied during inspection.
It is not. The invoice is only valid after it has been fiscally registered and the NIVF has been obtained, so an expense based on an invoice without an NIVF is not recognized.
NIVF is the unique invoice number returned by the platform after fiscalization. NSLF is the issuing system number, i.e., the software solution that issued the invoice. Both are mandatory elements.
For an expense of 600,000 lekë excluding VAT, the cost amounts to 210,000 lekë—namely 90,000 lekë in additional profit tax and 120,000 lekë in deductible VAT that is lost. On top of that comes the fine for failure to submit to fiscalization.
Within 72 hours of receiving the prepayment. The invoice is not issued until the service is completed.
Whenever the buyer is a business, and in any case when the value of an individual invoice exceeds 500,000 lek.
The invoice is not canceled. A corrective document is issued referencing the original invoice's NIVF, it is fiscalized, and the sales book is adjusted before the 11th. For the exact type of document and the deadline, write to us, as this is a point we verify with the official source.
Self-billing for the service received is performed by the 10th of the following month, and VAT treatment follows the rules of the place of supply.
Billing is stopped because without a certificate the invoice cannot be fiscally registered. The renewal is scheduled on the calendar two weeks before the expiration date.
Yes, without exception. The 0% rate eliminates the income tax payment on business income and only that, while the invoicing obligation remains fully in effect.
