Serbia: Is the new fiscalization system adopted in Serbia a modern E-Invoicing model?

The Serbia tax authority adopted a new fiscalization system in May 2021, which means that almost 250,000 traditional FCR (Fiscal Cash Register) users have to replace or adjust their existing billing system to comply with the new regulation.  Can all the taxpayers complete the transition before the deadline of November 1, 2021? Are the fiscal service providers ready for the new model?

Don’t worry too much about that! The good news is that The Minister of Finance of the Republic of Serbia, Siniša Mali, announced that the transitional period for adjusting to the new fiscalization model, which will last until April 30, 2022, begins on November 1, 2021. While the Ministry of Finance has allocated 6 billion dinars from the budget for the subvention program intended to cover the costs of implementing the new fiscalization model.

Besides the above deadline and budget from the Ministry of Finance, let take a look at the new fiscalizaiton system in detail.  Is it a modern E-invoicing model that can greatly reduce the costs of billing fiscal receipts and improve auditing efficiency?

Two critical concepts of modern e-invoicing mode are Clearance and Post-audit.

The post-audit model is also called “e-reporting” which is widely used in Euro, Africa and Asia.  In the post-audit model, the seller can issue an invoice to a client directly without any online audit process, but the tax authority enforces the use of fiscal modules to register the transaction data for tax amount auditing, invoice ID assignment, and data integrity verification in case of tax fraud behaviors. There are many fiscal modules used in the market such as the fiscal cash register, electronic signature device and fiscal printers.

Although the network is not necessary for the post-audit model, it is mandatory to upload the fiscalized receipts data in the fiscal module to the tax authority when the network is accessible. In one word, post-audit model means “Invoicing first, Uploading later”

The post-audit model

The clearance model is becoming popular in recent years with the development of information and communication technology. In the clearance model, the seller needs to upload his transaction data to the tax authority first for online auditing before billing operations. while buyers can’t receive any type of invoices (electrical or paper) unless the tax authority responds with a successful auditing response to the seller.  which means that the tax authority replaces all these fiscal modules by online invoice signing API through the high-speed internet connection.

The clearance means “Uploading first, Invoicing later”.  the clearance model was also called e-invoicing in LAC (Latin America and the Caribbean) for B2B scenarios had been adopted since 2004 and is extended in B2C scenarios now.

The Clearance Model of E-Invoicing

The Clearance Model

The new fiscalizaiton system in Serbia is such a modern E-invoicing model that contains both the clearance and post-audit models. we can see from the technical guidance that there are two types fiscal solutions exist in the new system: V-PFR(clearance) and L-PFR(post-audit)

V-PFR is an online invoice signing platform provided by Serbia tax authority to support the clearance e-invoicing model.

L-PFR are hardware/software modules that use their own fiscal invoice processor and which enables the issuance of fiscal invoices even in the event of temporary or permanent interruption of the Internet connection; all the signed invoices will be uploaded to the tax authority near real-time basis

Which should I choose?V-PFR or L-PFR?

It is hard to say which one is better for different users. Maybe you are considering the business interruption by the network failure in V-PFR solution, or the costs of new devices that comply with L-PFR solutions, even both of the two solutions can’t meet your requirements (supermarket with centralized backend Office system).  Let’s make a simple comparison of V-PFR and L-PFR from different aspects

comparison between V-PFR & L-PFR

For different end-users, there are many recommend scenarios lists as follows

Although the V-PFR is free, the government still recommends every premise to have at least one L-PFR in case of non-compliance tax fraud caused by internet issue in V-PFR scenarios

What is the most cost-effective fiscal solution for my business?

Maybe you are a traditional ECR user that doesn’t want to spend too much on the POS terminal cost and license fee of POS software, Or a supermarket owner that wants to find a “server to server” fiscal solutions that can be integrated with your BOS system for centralized high volume invoicing. please skip to our official website: for more information. we will give you the best solutions that can easily help you manage the fiscalizaiton transition in Serbia
