Mandatory invoicing is becoming a hot topic for everyone who issues or receives invoices. The major invoicing change is part of the digitalization of the tax agenda and a step towards Europe-wide mandatory e-invoicing planned for 2023.
Change is a law, not a choice – and that is why it pays to deal with it early and in a way that interferes with the daily functioning of your business as little as possible. Whether you are an accountant, a self-employed person, or a large or small company, with GRiT you will not have to worry about any extra agenda. We will solve everything for you and you will not even notice it.
What is mandatory e-invoicing and why is it being created?
Mandatory e-invoicing comes as a response to a long-term problem - tax evasion, different rules in individual countries, and the fact that in the digital age, we still work with inconsistent PDF files that someone has to manually check.
The principle is simple: an invoice will no longer be just a document for the customer, but a structured set of data that accounting systems and the state will be able to work with automatically. Thanks to this, financial administration will have an overview of transactions faster and companies will gradually get rid of manual work, rewriting and errors.
What legislation is mandatory e-invoicing based on?
The basis for the entire change is the European initiative ViDA (VAT in the Digital Age) . It expects VAT and invoicing data to be handled digitally, uniformly and to the same standard throughout the European Union.
By 2030, electronic invoicing and digital transaction reporting should be standard across the EU . But individual countries don’t have to wait until that date – and most of them don’t. That’s why we see today that some countries are already using e-invoicing routinely, while others are in the preparation phase.
What does the situation currently look like in Slovakia, the Czech Republic and the EU?
Slovakia: clear deadline and specific rules
Slovakia is among the countries that have decided to go the route of a national e-invoicing system . From January 1, 2027 , electronic invoicing will be mandatory for domestic transactions.
In practice, this means that companies and self-employed persons in Slovakia will have to issue and receive invoices in the prescribed electronic form. The system will cover both invoicing between companies (B2B) and communication with the state (B2G). The solution will also include the mandatory transfer of selected data to the financial administration.
It is important to note that these are not foreign invoices . The obligation applies only to transactions within Slovakia. Nevertheless, it makes sense to prepare today so that the solution will stand the test of time in the future.
Czech Republic: a matter of time, not a decision
There is no specific date yet for mandatory e-invoicing in the Czech Republic. However, the direction is the same as elsewhere in Europe. Czech legislation will have to adapt to the European framework and it is very likely that the obligation will appear before 2030.
For businesses, this means one thing: waiting until the last minute may not pay off. Being prepared today means less work and uncertainty tomorrow.
Europe: Italy, Poland and more
Some countries are ahead of the curve with e-invoicing. Italy has been operating its own system for several years. Poland is implementing the KSeF system. Other countries are in various stages of testing and legislative preparations.
Peppol: the basis of future European e-invoicing
The common denominator of all these solutions is the drive for data unification and automation . And this is where the European Peppol standard comes into play. (Pan-European Public Procurement Online). This is a standardized and secure network for the electronic exchange of business documents , thanks to which various invoicing systems, ERP solutions and government platforms can communicate with each other - regardless of the country in which they are located.
That is why Peppol is now being mentioned as a likely basis for future pan-European e-invoicing after 2030. However, there is no regulation that would specifically require member states to use this network. Peppol is rather the most realistic and widespread option today. For companies, this means only one thing: a solution that makes sense today must be compatible with Peppol. Otherwise, it risks having to be completely redesigned.
Why is e-invoicing a sensitive topic for companies, self-employed people and accountants?
Mandatory e-invoicing affects everyday practice. It is not just about issuing invoices, but also about continuity with accounting, ERP systems, control mechanisms and communication with the state.
Accounting firms will handle the change for dozens of clients. Self-employed people will not want to delve into technical details. Companies do not want to risk mistakes, fines, or extensive system modifications.
That's why it makes sense to have a partner who will take care of both the technical and legislative side of things.
