Companies have two months to start using only e-invoice system

The deadline for the full implementation of e-invoice system in companies is getting closer, with only two months left. As of January 1, 2023, companies will have to both send and receive invoices via the electronic invoicing system (EIS/SEF).

The Law on Electronic Invoicing came into force on May 1 and it applies to both public and private sector companies and legal entities.

Companies that do business with the public sector have had to issue invoices via the EIS since the beginning of May, and start receiving them from July 1st, be it invoices issued by public sector companies or individuals who choose to have their invoices delivered via the electronic system. From January 1 next year, issuing and storing electronic invoices will be mandatory in all transactions between private sector entities.

Tax advisor and member of the Board of Directors of the Tax Advisors Association of Serbia, Aleksandar Vasić, says that the law prescribes a phased implementation from the beginning of May this year, which is a good way to adapt to new way of sending and receiving invoices. However, he states that there were a lot of problems that were fixed on the fly.

“The technical instructions and the functionalities of the electronic system/website are still being adapted to the needs of its users, which is one of the biggest shortcomings of this system at the moment,” says Vasić in an interview with

The advantages, he says, are numerous and will be fully visible once the system’s initial weaknesses are eliminated and users completely adapt to it. “The electronic invoicing system will ensure faster communication and provide greater legal certainty, but will also provide opportunities for greater automation in data processing”, he adds.
